5) The process of calculating the area of a single stroke from the cadastral map original map data.
It becomes more.

  As described above, in a one-stroke survey, a rough survey survey is performed before conducting a precise survey, but when creating a survey map, etc., unique identification information is used to identify the site, the survey map, and numerical cadastral data. In order to link with, the number etc. (identification information) is attached to the writing boundary point. By linking in such a way, even when corrections are made, it is easy to check the survey results by specifying the writing point with identification information, and it is generally done from before and after the start of numerical cadastral registration .

  Conventionally, in order to match the brush border pile with the position information or measurement information (hereinafter collectively referred to as survey information) for the brush border pile, the identification information of the brush border pile is read out during the surveying work. Since the work is performed one by one, the work is not simply complicated, and there is a problem that the identification code is misidentified and miswritten.

  In order to solve such a problem, a GPS device built in the pole using a driving head with a built-in information storage unit and a pole that is detachably attached to the driving head and reads / writes to / from the information storage unit Japanese Patent Application Laid-Open Publication No. 2004-228688 discloses a method of performing surveying by writing position information of a writing boundary point measured through the receiving antenna to the storage unit and reading the position information with an input / output device. In addition, in order to improve the measurement accuracy of the GPS survey, in order to accurately obtain the position information of the reference point, which is a requirement for accurately performing the one-stroke survey, the reference point is accurately determined from the known reference point. The following patent document 2 is disclosed as a technique for coordinating with the above.

Japanese Patent Laid-Open No. 7-19079 JP 2004-301598 A

  The patent document 1 uses the system disclosed in the document to obtain the placement position of the brush border pile by surveying, and records the obtained position in a field book or a recording device. It is said that it is not necessary to collate the brush border pile recorded on the field book or recording device and its placement position with the local brush border pile for every surveying work. Further, Patent Document 2 describes that the degree of freedom of the surveying method is increased by enabling the accuracy evaluation of the reference point surveying.

  However, even if only the placement position of each brush border pile is clarified by the method disclosed in Patent Document 1, since the land shape is various, the connection between the brush border points is not clear. The correct boundary line according to the shape of the land cannot be determined, and it is undeniable that the land may be surveyed as a land with a shape far from reality. Further, even when the accuracy of reference point surveying can be evaluated by the method described in Patent Document 2 and surveying can be performed at a site where satellite reception is not possible, at the time of pen point surveying performed for many writing point points by the method. It cannot be expected to contribute to improvement of workability and work efficiency.

  In other words, in order to realize highly applicable surveying for various lands, it is still necessary to verify the need for the above-mentioned brush graphic information and the identification information of the survey map and the identification information attached to the brush border pile. There is no change in the complexity of the collation work.

  The present invention has been made in view of the above circumstances, and reduces the complexity of surveying work, eliminates misunderstandings of misprinting points, and performs highly applicable surveying on various forms of land. The purpose is to provide a surveying system that can be realized.

  The surveying system according to the present invention, which has been made to solve the above-mentioned problems, includes a writing circle pile in which identification information that is readable electromagnetically or optically is recorded, and identification from the writing circle pile on the writing circle pile. Survey poles with pile discriminating means for reading and recording information electromagnetically or optically, and the placement position of the brush pile where the identification information is read by aligning with the survey pole on the brush pole for reading the identification information Identification information for measuring the relative positional relationship with respect to a point (polygonal point) and forming measurement information, and identification information for the brush border pile output from the survey pole (including that of the reference pile discrimination means) And an input means, a measurement information input means for inputting the measurement information output from the total station, and a data collector having a storage means for holding them. To.

  Depending on the case, a pile boundary in which identification information that can be read electromagnetically or optically is recorded, and a pile identification that reads and records the identification information electromagnetically or optically from the brush boundary pile on the brush boundary pile And a surveying pole equipped with a GPS receiving means for receiving the signal from the artificial satellite on the writing circle pile for reading the identification information and reading the writing point position information of the writing circle pile, and on the writing circle pile for reading the identification information The total station that measures the relative positional relationship with the reference point and forms the measurement information with respect to the placement position of the writing pile where the identification information is read by aligning the direction with the surveying pole, and the identification of the writing pile output from the surveying pole Identification information input means for inputting information, position information input means for inputting the writing point position information output from the surveying pole, and the measurement information output from the total station Force measuring information input means, and may be a surveying system comprising the data collector comprises a storage means for holding them.

  In surveying work, it is necessary to generate information that triggers acquisition of various information used for calculation of surveying information from appropriate elements that constitute the system according to the surveying form. Trigger generating means for transmitting trigger information during processing, communication means for receiving trigger information transmitted by the total station on the surveying pole, operating in response to the trigger information, and outputting identification information of the brush border pile A pile discriminating means, and a communication means for transmitting the identification information. The data collector includes a communication means for receiving the identification information output from the surveying pole. Provided with information request means for transmitting request information when reading the writing point position information of the pile, the surveying pole, A communication means for receiving the request information transmitted by the data collector, a pile discriminating means which operates in response to the request information and outputs the identification information of the brush border pile, and operates in response to the request information to obtain the writing boundary point position information. A GPS receiving means for outputting and a communication means for transmitting the identification information and the writing point position information; and a communication means for receiving the identification information and the writing point position information output from the surveying pole in the data collector. The structure provided, the surveying pole is provided with starting means for operating the pile discriminating means and the GPS receiving means, and the identification information of the brush border pile read by the pile discriminating means and read by the GPS receiving means Communication means for outputting the writing point position information, the identification information and writing point position information output from the surveying pole in the data collector. Configuration having a communication means for receiving and the like.

  The data collector includes brush graphic information input means for registering the positional relationship of the brush boundary points with the identification information as brush graphic information, and further includes the measurement information or position information held by the data collector, and the brush boundary Based on the pile identification information and the brush figure information of the brush boundary point, it is desirable to have a configuration including calculation means for calculating survey information with the placement position of the brush boundary pile as the brush boundary point. As a method of linking the collected measurement information with the reference point that is the base point of the measurement, the identification information attached to the reference pile placed at the reference point that is the set position of the total station is automatically read and converted into data In order to provide a function to perform, the total station is provided with an under vibration that hangs on the reference pile from its measurement base point, and the under vibration is electromagnetically applied to the surface of the reference pile. Comprises reference pile discriminating means for reading and recording identification information recorded by an optical method by electromagnetic or optical means, and holds the recorded identification information together with measurement information obtained by the total station (see FIG. 1 or FIG. 10). ) It can also be configured as a surveying system.

  As a means for recording identification information in a brush border pile, a recording method that can be read in contact or non-contact, such as a bar code, an IC tag, or a magnetic seal, may be used. Means can be used.

  In addition, measuring the relative positional relationship with the reference point for the placement position of the writing pile where the identification information is read by aligning the direction with the surveying pole on the writing pile that reads the identification information This means that the reading and measurement of the surveying pole by the total station are performed as a set of processes, such as being performed simultaneously or sequentially. Similarly, receiving a signal from an artificial satellite on the writing stake that reads the identification information and reading the writing point position information of the writing stake are the reading of the identification information by the surveying pole and the writing by the GPS receiving means. It means that the derivation of the border point position information of the border pile is performed as a set of strokes.

  The measurement base point is a base point as a measuring instrument when the relative position of the total station with a survey pole as a target is measured. The reference point is also a point called a polygon point determined by a cadastral map root polygon survey (reference point survey) or the like, and is a point where the measurement base points of the total station are matched in the case of a polygon survey or a one-stroke land survey.

  The surveying system according to the present invention is a surveying system used for surveying methods and surveying methods that involve verification of the writing boundary point position information of the brush border pile and the local brush border pile as before. Reading and measurement of the survey pole by the total station, or derivation of the writing point position information of the brush border pile by the GPS receiver means that the survey pole is erected on each brush border pile. Since it is constructed as a system that can be performed in a pair of processes, the complexity of reading out the identification information of the brush border pile at the time of surveying work in order to match the brush border pile with the survey information, and the identification code Misunderstandings can be eliminated. If the measurement processing by the total station is incorporated into the system as described above, it is not possible to make surveying impossible at a site where satellite reception is not possible, unlike surveying that relies on GPS alone.

  Moreover, even if a land having a complicated shape is a survey target, there is provided a brush graphic information input means for registering the brush graphic information of the brush boundary point as the brush graphic information of the brush boundary pile having the identification information. This makes clear the connection of the brush boundaries that make up the outer edge of the survey topography. As a result, a correct boundary line in accordance with the shape of the land at the site is determined, and accurate cadastral map original map data as a surface having a shape in accordance with the reality can be obtained.

  The data collector is attached to or connected to the total station of the surveying system, and the total station and the surveying pole are communicated with the communication means of the data collector. Or, if the surveying system is provided with wireless communication means for transmitting and receiving the identification information and the writing point position information, the various information can be collected in the data collector simultaneously with the measurement work by the surveying pole and the total station. The work efficiency and work accuracy can be improved.

  Furthermore, the total station is provided with an under vibration that hangs down on the reference pile from its measurement base point, and the identification information recorded on the surface of the reference pile by an electromagnetic or optical method is electromagnetically or optically recorded on the under vibration. By using a surveying system with reference pile discriminating means that reads and records more appropriately, it is possible to automatically link and record measurement information collected by the total station, a reference point that is the base point of the measurement, and its position. It will be possible.

Hereinafter, embodiments of a surveying system and a total station according to the present invention will be described with reference to the drawings.
The surveying system illustrated in FIG. 1 includes a plurality of brushwork piles 1 that are placed at the boundary of a brushstroke that is a surveying site, and a surveying pole 3 that stands on the brushwork pile 1 during surveying. And a total station 4 that measures the distance to the object using the surveying pole 3 as an object and measures the relative angle with respect to the direction when the other surveying pole 3 is aimed.

  The total station 4 measures the positional relationship with the object using the light wave measuring means 19 and records it as measurement information in the memory as the storage means 20 and also appropriately sends it out via the communication means 21 using various interfaces. It can be output. The total station 4 sets a reflector called a prism on the object to be surveyed, receives trigger information, emits light toward the prism by the light wave measuring means 19, and returns after being reflected by the prism. Measurement process that measures the distance using the phase difference of the measured light, for calculating coordinates based on the relative positional relationship (distance and angle) with a known point, and trigger information A non-prism type total station that measures the distance using the time it takes for the object to receive and irradiate the target with infrared laser light and returns, and then calculates the azimuth using a magnetic compass. Therefore, a total station that performs measurement processing that does not require a known point is introduced.

  The example shown below is an example of a surveying system using a total station that uses reflected light of a prism and is equipped with a communication means 21 for exchanging information with the outside of the apparatus.

  The brush border pile 1 incorporates IC tags 22 in which different identification information is recorded. The IC tag 22 in the example includes a power supply circuit (self-excited power supply circuit) 44, a CPU 38, a memory 39, a modulation circuit 40, a demodulation circuit 41, a radio frequency (RF) circuit 42, and a tag antenna 43 (see FIG. 6).

  The surveying pole 3 performs non-contact communication with the IC tag 22 to read the identification information unique to each brush pile, and the GPS that receives the signal from the artificial satellite and reads the position information of the surveying pole 3 A receiving means 16 and a communication means 23 for exchanging the identification information and the writing point position information (only the identification information may be used when the GPS receiving means 16 is not used) externally. On its side surface, a reflector called a prism is provided.

  The pile discriminating means 2 includes a power supply circuit (separate excitation type power supply circuit) 31 including a storage battery and the like, like the IC tag 22, a CPU 32, a memory 33, a modulation circuit 34, a demodulation circuit 35, a radio frequency (RF). The circuit 36 and the search antenna 37 are configured, and the search antenna 37 is set at the lowest part of the surveying pole 3 (see FIG. 6). The CPU 32 and the memory 33 constituting the pile discriminating means 2 also serve as the control means for the GPS receiving means 16 and the communication means 23 provided in the surveying pole 3.

  The GPS receiving means 16 receives time triggers and continuously receives time data and position data (hereinafter referred to as position data, etc.) from a plurality of satellites orbiting around the earth (at least three for calculating altitude at least three). To acquire position data continuously (RTK-GPS method) by communicating with a surveying pole or the like installed at a reference point (fixed point) where the position coordinates are fixed, or Communicates with position correction information distributors that continuously acquire position data, etc. from multiple satellites, communicate with existing electronic reference points with fixed position coordinates, acquire position data, etc., and provide position correction information Then, position correction information is acquired (VRS-GPS method), the current position is calculated, and position information consisting of latitude, longitude, altitude, and direction is read. The GPS receiving means 16 in the example acquires position data or the like via the GPS antenna 24 set on the head of the surveying pole 3, and guides the position information of the position where the surveying pole 3 is set and records it in the memory. .

  In particular, when the VRS-GPS method is employed, a terminal device 25 for communicating with a position correction information distribution company (hereinafter referred to as a distribution company 26) is attached to the GPS receiving means 16. The terminal device 25 transmits the position information (hereinafter referred to as observation position information) to the distributor 26 and receives position correction information returned in response thereto. The GPS receiving means 16 immediately performs a baseline analysis using the position correction information by the information correction means 48, and derives and records the writing point position information with the observation position information corrected in the memory.

  The identification information and the writing point position information obtained as described above are transmitted to the data collector 9 by the communication means 23 of the surveying pole 3. Note that the data collector 9 is built in either the surveying pole 3 or the total station 4 (see FIG. 11), and is connected separately to the surveying pole 3 or the total station 4 so that it can be wired. Any of the above-described configurations and a configuration that exists as a separate body and exchanges information by wireless communication (see FIG. 1, FIG. 12, or FIG. 13) may be employed. Accordingly, the communication means used for communication performed between the data collector 9, the surveying pole 3, or the total station 4 includes not only communication between devices but also communication between devices and communication performed between IC chips. Those that perform on-board communication are also included.

  In the following example, as shown in FIG. 1, the total station 4 and the data collector 9, the total station 4 and the survey pole 3, and the survey pole 3 and the data collector 9 are wirelessly connected together to exchange information. However, it goes without saying that such a connection mode can be changed as appropriate, for example, by replacing it with a wired connection.

  The data collector 9 includes a wireless communication means for exchanging identification information and writing point position information with the surveying pole 3, a wireless communication means for transferring measurement information with the total station 4, and a writing point (writing point 1 Rough placement position information, the pile material information, or the branch point information, etc.), and brush graphic information such as connection information indicating the connection between the brush boundary points is registered with the identification information. The brush graphic information input means 5, the identification information input means 6 for reading the identification information of the brush border pile 1 from the surveying pole 3 via the wireless communication means, and the brush boundary from the survey pole 3 via the wireless communication means The position information input means 11 for reading point position information, the measurement information input means 7 for reading the measurement information from the total station 4 via the wireless communication means, and various pieces of information are held. Are provided with a 憶 means 8.

  The brush graphic information input means 5 may be the brush graphic information input means 5 that records the brush graphic information in the storage means 8 through manual input means using, for example, a tablet or a keyboard. 3 may be used as the brush graphic information input means 5 that records the brush graphic information that can be obtained in 3 in the storage means 8 of the data collector 9 via the communication means 23 of the surveying pole 3 and the wireless communication means of the data collector 9. .

  The brush figure information input means 5 in this example is a pen computer (a so-called tablet computer) that is a data collector 9 and directly inputs data to a display unit 27 such as an LCD using a pen (stylus) as an input device. To the background registration means 28 for taking in topographical map (topographical information) data from various recording media or the Internet as a background, and to the display unit 27 on which the topographical map is displayed. Survey information such as identification information written by an input device, or survey information registration means 29 for capturing survey information received via the wireless communication means, and a brush graphic for storing brush graphic information composed of the topographic information and the survey information And information storage means 30.

  When obtaining the survey information, for example, the identification information is collected from the brush pile 1 where the surveying pole 3 is set up, for example, by the pile discriminating means 2 in a manner described later (see FIG. 12), and the position data is collected. When necessary, for example, rough position data from the satellite is sequentially acquired in the D-GPS format or the like (see FIG. 13), and these are linked and stored. In addition, when only the identification information is to be confirmed during the survey, the survey pole 3 is provided with a display means for displaying the detection result of the identification information by the pile discrimination means 2 (see FIG. 14). Thus, based on the identification information, the positional relationship of each brush border pile 1 can be collated with a brush figure.

  The trigger for collecting the position data and the like by the surveying pole 3 may employ any of the methods described later that relate to the surveying pole 3, but will be described later when using the tablet computer. The third system form is adopted, and the writing boundary points (A, B, C, D, E, F, G, and so on in FIG. 4) are measured objects of the topographic map captured as the background in the display unit 27 of the data collector 9. Alternatively, a method of issuing request information by applying pressure to the portion H) with the input device seems to be preferable.

  Various information stored in the data collector 9 as described above is calculated according to the type of information after the collection of information at the site is completed by the computing means 10 that is separately connected or integrally configured. Is called. For example, with respect to the coordinate data which is the stroke boundary position information read by the position information input means 11, the brush figure and the area of the surveying site are calculated while referring to the previously registered brush figure information. On the other hand, for distance data and angle data as measurement information read by the measurement information input means 7, based on the information, the brush figure and area of the surveying site are calculated with reference to pre-registered brush figure information. .

  As described above, by adopting the RTK-GPS method or the VRS-GPS method for the GPS receiving means 16, the survey using the GPS receiving means 16 (hereinafter referred to as GPS surveying) and the total station 4 are used. Therefore, most of the usage modes of the surveying system having both the GPS receiving means 16 and the total station 4 are only GPS surveying or mountainous remote areas. Or any of the normal surveys that would be required in an area surrounded by high-rise buildings, but if necessary, after performing the GPS survey, the normal survey will be performed to verify the accuracy of the survey Can also be used.

  In the surveying system in this example, the operation from the start of the surveying process to the surveying pole 3 or the total station 4 by the operator at the site to the recording of various information in the memory included in each is performed as a series of processing steps. If necessary, the information is recorded from the surveying pole 3 or the total station 4 to the data collector 9, and the information is also supplied to the calculation means 10 to give information about all the brushstroke piles. A series of processes can be expanded as appropriate until a brush figure derivation process and an area calculation process are performed on the condition of the above.

  Moreover, the optimal transmission source of the operation triggers of the constituent elements of the system should be different depending on whether the survey to be performed is the normal survey or the GPS survey, or the wide-area survey or the survey of the narrow land. That is, in the case of performing GPS surveying, it is desirable to generate an operation trigger by looking at the state where the surveying pole 3 stands vertically on the brushwork pile. Or a starting means 17 for operating the GPS receiving means 16 may be provided. When performing measurement using the total station 4, it is desirable to generate an operation trigger by looking at a state where the aim of the total station 4 is aligned with the prism of the survey pole 3. Should be provided. Furthermore, information requesting means 15 for generating request information for operating each functional means from the data collector 9 to the total station 4 or the surveying pole 3 may be provided.

  Incidentally, in the example, the total station 4, the surveying pole 3, and the data collector 9 are all provided with the switch for generating an operation trigger for each component of the surveying system.

  Hereinafter, a mode of a series of processes up to acquisition of identification information and writing point position information or measurement information will be exemplified.

  For example, in the case of the first system configuration in which only GPS surveying is performed (see FIG. 2), the operator stands the surveying pole 3 vertically on the brushwork pile 1 to be measured, and at an appropriate timing. The starting means (switch, etc.) 17 of the surveying pole 3 is turned on. The CPU 32 of the surveying pole 3 that has detected the trigger information by the starting means 17 operates the respective components of the surveying pole 3, and the pile discriminating means 2 (see FIG. 6) is controlled by the CPU 32. 34 and the search antenna 37, a specific frequency at which the RF circuit 42 of the IC tag 22 resonates is emitted, and the GPS receiving means 16 receives a signal from the artificial satellite via the GPS antenna 24 and obtains position information of the survey pole 3 Read (see FIG. 2A).

  The IC tag 22 with a built-in brushstroke pile that has received the specific frequency by the RF circuit 42 rectifies the mutual induction power of the RF circuit 42 by the power supply circuit 44 and activates the circuit constituting the IC tag 22. Based on the request from the pile discriminating means 2 taken out by the demodulation circuit 41, the individual identification information recorded in the memory 39 is read out, and the specific frequency on which the identification information is put by the modulation circuit 40 and the RF circuit 42 Is transmitted from the tag antenna 43.

  The pile discriminating means 2 of the surveying pole 3 receives the reply radio wave, detects the identification information read from the IC tag 22 of the brushwork pile 1 by the demodulation circuit 35 and records it in the memory 33.

  On the other hand, the CPU 32 of the survey pole 3 that has detected the reading of the position information from the artificial satellite further operates the terminal device 25, and the position coordinates of the observation position information are determined via the communication means of the terminal device 25. Survey pole (or a communication facility that distributes the position coordinates of the reference point correspondingly) 3 established at the reference point (fixed point) being sent to the distribution provider 26 or returned to it Position correction information is received via the communication means of the terminal device 25. The information correction means 48 of the GPS receiving means 16 immediately performs a baseline analysis using the position correction information, and derives and records in the memory 33 the writing boundary point position information obtained by correcting the observation position information.

  The CPU 32 of the surveying pole 3 detects the completion of the information acquisition process of the pile discriminating means 2 and the GPS receiving means 16 by reading the writing boundary point position information in the memory 33 and reads it from the brush border pile 1. The identification information and the writing point position information derived by the GPS receiving means 16 are read from the memory 33 and transmitted to the data collector 9 by the communication means 23.

  The data collector 9 reads the identification information of the brush border pile 1 by the identification information input means 6 through the communication means 45 and records it in the storage means 8, and also stores the brush information by the position information input means 11 through the communication means 45. The writing point position information of the boundary pile 1 is read and recorded in the storage means 8 (see FIG. 2B). When the data is written in the storage means 8, the collation means 46 of the data collector 9 receives from the surveying pole 3 the identification information attached to the brush graphic information previously taken in by the brush graphic information input means 5. The identified identification information is collated, and a process of linking with the writing point position information of each writing point 1 whose identification information matches is performed.

  For example, in the case of the second system configuration in which the normal survey using the total station 4 is performed (see FIG. 3), one of the workers stands vertically on the brushwork pile 1 as the measurement target. Then, the other operator performs an operation of turning on the measurement start switch as the trigger generating means 12 of the total station 4 at an appropriate timing by aligning the aim of the total station 4 with the prism of the surveying pole 3 (FIG. 3A). reference). The communication means 21 of the total station 4 receives the ON information, generates trigger information synchronized therewith, and transmits it to the surveying pole 3.

  The light wave measuring means 19 of the total station 4 receives the trigger information and hits the prism of the surveying pole 3 as described above to emit light and detect the reflected light to measure the distance. When measuring the distance, the relative angle of the light emission direction with respect to the reference azimuth is detected and recorded in the storage unit 20 as measurement information together with the measured distance data.

  The relative positional relationship with the surveying pole 3 aimed by the total station 4 is performed in a state in which the measurement base point of the total station 4 is aligned with the reference point using a centripetal device. The centripetal device in this example is a downward swing 13 that is suspended from the measurement base point, and on the reference pile 18 that receives trigger information and is placed at the reference point and has an IC tag built-in. The identification information from the reference pile 18 is read out electromagnetically or optically, for example, using the same structure or method as the pile discriminating means 2 and stored in the storage means 20 as measurement information together with the relative angle and distance data. Reference pile discriminating means 14 for recording is provided.

  By recording the measurement information in the storage means 20, the CPU of the total station 4 detects the completion of the information acquisition process in the total station 4, reads the measurement information from the storage means 20, and operates the communication means 21. The data is transmitted to the data collector 9 (see FIG. 3A).

  On the other hand, the CPU 32 of the surveying pole 3 that has detected the trigger information operates the pile discriminating means 2 and the GPS receiving means 16 of the surveying pole 3 as appropriate, and the pile discriminating means 2 controls the modulation circuit under the control of the CPU 32. A specific frequency at which the RF circuit 42 of the IC tag 22 resonates through 34 and the search antenna 37 is emitted. In the case of the normal survey, the GPS receiving means 16 is selectively operated by the measurement start switch (trigger generating means 12) according to the operator's request, and when the GPS receiving means 16 is operated, The writing point position information of the surveying pole 3 is read in the same manner as the GPS surveying in synchronization with the emission of the specific frequency (see FIG. 3B).

  The IC tag 22 built in the brush border pile 1 having received the specific frequency by the RF circuit 42 rectifies the mutual induction power of the RF circuit 42 by a power supply circuit, and activates the circuit constituting the IC tag 22. Based on the request from the pile discriminating means 2 taken out by the demodulation circuit 41, the individual identification information recorded in the memory 39 is read out, and the specific frequency on which the identification information is put by the modulation circuit 40 and the RF circuit 42 Is transmitted from the tag antenna 43.

  The pile discriminating means 2 of the surveying pole 3 receives the reply radio wave, detects the identification information read from the IC tag 22 of the brushwork pile 1 by the demodulation circuit 35 and records it in the memory 33.

  On the other hand, the CPU 32 of the survey pole 3 that has detected the reading of the position information from the artificial satellite further operates the terminal device 25, and the position coordinates of the observation position information are determined via the communication means of the terminal device 25. Survey pole (or a communication facility that distributes the position coordinates of the reference point correspondingly) 3 established at the reference point (fixed point) being sent to the distribution provider 26 or returned to it Position correction information is received via the communication means of the terminal device 25. The information correction means 48 of the GPS receiving means 16 immediately performs a baseline analysis using the position correction information, and derives and records in the memory 33 the writing boundary point position information obtained by correcting the observation position information.

  The CPU 32 of the surveying pole 3 detects the completion of the information acquisition process of the pile discriminating means 2 and the GPS receiving means 16 by reading the writing boundary point position information in the memory 33 and reads it from the brush border pile 1. The identification information and the writing point position information derived by the GPS receiving means 16 are read from the memory 33 and transmitted to the data collector 9 by the communication means 23.

  The data collector 9 reads the identification information of the brush border pile 1 by the identification information input means 6 through the communication means 45 and records it in the storage means 8, and also stores the brush information by the position information input means 11 through the communication means 45. The writing point position information of the boundary pile 1 is read and recorded in the storage means 8 (see FIG. 3C). When the data is written in the storage means 8, the collation means 46 of the data collector 9 receives the identification information attached to the brush graphic information previously taken in by the brush graphic information input means 5 and the survey pole 3. The identified identification information is collated, and a process of linking with the writing point position information of each writing point 1 whose identification information matches is performed.

  For example, in the case of the third system configuration in which the data collector 9 gives an operation trigger for prompting the surveying process to the total station 4 or the surveying pole 3 and the data collector 9 mainly performs the surveying process, the data collector 9 9 includes information requesting means 15 for transmitting request information through the communication means 45 when reading the writing boundary point position information of the writing boundary pile 1, and request information transmitted by the data collector 9 to the surveying pole 3. Communication means 23 that receives the request information, pile determination means 2 that operates upon receiving the request information and outputs identification information of the brush border pile 1, and GPS that operates upon receipt of the request information and outputs the writing boundary point position information What is necessary is just to set it as the structure provided with the communication means 23 which transmits the receiving means 16 and the said identification information and writing boundary point position information.

  The information request means 15 is a functional means of the brush graphic information storage means, and is a writing boundary point that is a measurement target of a topographic map (terrain information) captured as a background in the display unit 27 of the data collector 9. There is a technique in which request information is issued by applying pressure to the part (A, B, C, D, E, F, G, or H in FIG. 4) with the input device.

  Further, the process of acquiring the identification information and the writing point position information or the measurement information is the same as the other series of processing modes described above, and the data collector 9 is transmitted by the identification information input means 6 via the communication means 45. The identification information of the brush border pile 1 is read and recorded in the storage means 8, and the position information input means 11 or the measurement information input means 7 through the communication means 45 is used to determine the brush border point position information or measurement of the brush border pile 1. Information is read and recorded in the storage means 8 (see FIG. 3C). When the information is written in the storage means 8, it is attached to the brush graphic information previously taken in by the brush graphic information input means 5 by the collating means 46 of the data collector 9, and by the input device of the information requesting means 15. The specified identification information and the identification information received from the surveying pole 3 are collated and linked with the writing point position information of each writing point where the identification information matches, and the measurement information and the identification taken together with the writing point position information. Performs processing to link information.

  The computing means 10 includes the identification information registered by the brush graphic information input means 5 of the data collector 9, the brush graphic information, and the survey information, and the identification obtained by the first system form to the third system form. The information, the writing point position information, and the measurement information are linked and analyzed based on the identification information. At that time, the connecting point 47 is connected to the writing points constituting the one stroke according to the brush figure information to create the original map data, and the checker map data and the survey map are checked by the checking unit. Are quickly collated with the data that constitutes the data, area calculation processing, and the like, and information derived by these processes is output as one-stroke survey information.

  The surveying system according to the present invention can automatically create the cadastral map original map data. Therefore, in the case of one-stroke ground survey (brush point survey), real-time processing including calculation means is possible, and verification after surveying is possible. Since the process can be performed automatically, the work efficiency is greatly improved, and the work time and the man-hours can be reduced. Moreover, the same effect can be acquired even if it exists in cadastral map root polygon survey (reference point survey).
