Description

Digital map editing system {Surveying system}

The present invention relates to a digital map editing system, and more particularly, to a digital map editing system for editing a digital map in order to ensure the accuracy of the digital map created earlier.

The digital map means that digital maps are produced by digitally analyzing various topographical data obtained by surveying maps, aerial photographs, satellite images, etc. from existing analog paper maps. In general, the process of constructing a digital map is as follows.

When the paper map is digitized or scanned to form a digital map, the paper map is converted into an actual coordinate system according to the user's purpose through coordinate transformation.

After that, the terrain data is input to the digital map that establishes the topological structure to grasp the inter-location and the relationship between the spatial objects.

The digital maps produced in this way enable faster and more accurate map retrieval than paper maps, and are superior in information management and usability to support various planning and decision making.

However, since the topographical data input to the digital map is input through the reading of aerial photographs and satellite images, the digital map which symbolizes and simplifies the topographical information obtained from the orthogonal photographs has a lot of difference from the shape of the real thing, and thus the variation of the topography and facilities. It is difficult to guarantee the accuracy of the terrain data 100% because it does not reflect the fact as it is.

In particular, recently, the development of building technology, such as the form of the building has been limited in expression, such as the form of the roof can not be identified in the orthogonal picture, the building is limited in expression.

As a result, digital map makers perform field surveys to ensure the accuracy of digital maps, and there is a need for an operation to effectively and accurately edit digital maps and topographical data of digital maps while performing field surveys.

In Korean Patent Registration No. 10-0929892, the route information of the editing system is measured and compared with the route information on the previously stored digital map, and then merged, divided, or modified specific areas of the digital map according to the comparison result. A method of editing and editing of mismatched attribute information is disclosed. However, since this is only editing the digital map for the field survey area, there is a problem that the accuracy of the digital map is still not 100% guaranteed in the case where the field survey is not performed.

On the other hand, as the importance of GIS increases, the digital map information used in public institutions and specific institutions is produced and sold commercially for the general public. However, there are cases where illegally produced GIS information is illegally distributed or stolen, and efforts are being made to prevent it when producing digital maps.

In detail, the communication interface 11 of the editing terminal 10 may be a transceiver or a modem that mediates a connection to the communication network 20. Therefore, the editing terminal 10 may transmit / receive various information with the GIS server 30 through the communication network 20.

The measuring unit 12 of the editing terminal 10 measures the position coordinates of the editing terminal 10 and transmits the measured coordinates to the GIS server 30.

A conventional microprocessor may be used. The edit mode determination unit 15 determines, by the input of the input unit 14, the numerical map editing mode as at least one of merging / dividing / modifying, or the movement route measured by the measuring unit 12 and route information included in the numerical map. The digital map editing mode can be determined by comparing the two values. That is, the editing mode determination unit 15 compares the route information on the numerical map with the movement route of the editing terminal, and selects the merge editing mode when there is a route not being routed through the editing terminal among the route information on the numerical map. If there is a route that is not included in the route information on the numerical map among the movement routes passed through the editing terminal, select the segmentation editing mode, or if the accuracy of the movement route accuracy of the editing terminal is less than the threshold, then select the edit mode, and then Is transmitted to the editing unit 16.

The editing unit 16 of the editing terminal 10 edits route information by merging, dividing, or modifying polygons on the numerical map according to the determination result of the editing mode determination unit 15, and receives the attribute change signal from the input unit 16.

Inserts a watermark code into the polygon on the digital map. For example, the edit mode determination unit 15 checks whether the watermark code is inserted into the polygon on the digital map received from the GIS server 30, and if the watermark code is not inserted, the water for the polygon is inserted. A confirmation message indicating whether or not to insert a mark is output to the display unit, and when an approval signal is input through the input unit, a watermark code is inserted into the corresponding polygon.

The communication network 20 connects the editing terminal 10 and the GIS server 3 by wireless communication to transmit / receive various information between the editing terminal 10 and the GIS server 30. In this case, the communication network 20 is preferably a communication network capable of performing both wired and wireless communication, and may be changed by a user's selection.

It may include, it is preferably linked to or include coordinate information 322, polygon attribute information 323, route information 324, terrain attribute information 325 and field survey information 326. The coordinate information 322 includes coordinate values for polygons that classify the regions constituting the digital map according to attributes. In this case, the coordinate information 322 may be stored by mapping the map information of the region corresponding to the region name or region name stored in the numerical map 321. The coordinate value of the polygon refers to the coordinate value of a plurality of nodes constituting the polygon, and the interval of the plurality of nodes may be preset by the digital map maker when generating map information and attribute information by analyzing and reading image data. have. The polygon attribute information 323 may be stored by mapping to a polyline included in the polygon, and represent boundary attribute information. The route information 324 is a movement route that is read from a digital map generated by a survey map, aerial photographs, satellite images, etc., and maps the map information of the region corresponding to the region name or region name stored in the digital map 321. It may be stored, and is preferably made of a combination of coordinate values, the movement path means a path that can be moved by a person and a moving means including a bicycle, a motorcycle and a vehicle.

The terrain attribute information 325 may be stored by mapping the map information of the region corresponding to the region name or region name stored in the numerical map 321, and the residential area, agricultural area, factory area, commercial area, forest area, and wild land And information about a specific region including a wetland region and the like, and can be typically analyzed and read from image data such as survey maps, aerial photographs, and satellite images. In addition, the terrain attribute information 325 may be classified for each terrain attribute by a polygon generated by a connection of a plurality of nodes, and the terrain attribute information 325 may be an area constituting a digital map.

Next, a method of editing a numerical map according to the present invention will be described with reference to FIGS. 2 to 7. 2 is a flowchart illustrating a numerical map editing method according to an exemplary embodiment of the present invention, and FIGS. 3 to 7 are screen views illustrating a numerical map editing method according to an exemplary embodiment of the present invention.

First, the site survey area selection unit 19 compares the route information on the digital map with the actual site survey information of the corresponding area, determines whether the path is matched, and calculates the location information (coordinate value) of the area with the mismatched path. Guide through the display (S200).

The site survey area selecting unit 19 outputs the actual survey information of the area stored in the site survey information 326 of the GIS server 30 to the display unit, and compares it with the numerical map. Therefore, the site survey area selecting unit 19 first determines a region where the numerical map created does not match the actual survey information, selects it as a site survey area, and guides it.

Then, in performing the site survey in the guided area, the measurement unit 12 measures the position coordinate value of the editing terminal 10, and transmits it to the GIS server 30 (S201). At this time, the measurement unit 12 is a GPS device, it is possible to accurately measure the coordinate value of the location where the editing terminal 10 is located, and can measure the coordinate value for the movement path in real time when the editing terminal 10 is moved. .

Next, the GIS server 30 edits the numerical map including coordinate information, polygon attribute information, route information, and terrain attribute information of the region in which the editing terminal 10 transmitted from the measuring unit 12 is located. The display unit 13 transmits the output to the display unit 13 (S202).

More specifically, the numerical map extracted in step S202 and output to the display unit 13 of the editing terminal 10 may be displayed as shown in FIG. 3.

In FIG. 3, A1 to A6, B1, C1, C1-1 to C1-3, and C4 to C6 each represent terrain attribute information and an area having respective terrain attribute information. In addition, the boundary of each terrain attribute information is a polygon, and each polygon is composed of a plurality of nodes. Although not shown, the coordinate values of each node may also be displayed in FIG. 3. At this time, the interval of each node may be an interval stored in the coordinate information 322, it is preferably set by the input of the input unit 14 in the editing terminal 10. In addition, it is preferable that the polygon becomes curved as the interval between nodes forming each polygon becomes narrower.

In this case, the editing unit 16 may delete some of the terrain attribute information on the numerical map output to the display unit 13 for easier editing of the numerical map. That is, the editing unit 16 may delete the area corresponding to the terrain property information input from the input unit 14 and the area and coordinate values corresponding to other terrain property information except for the coordinate values corresponding to the area from the display unit 13. Can be. More specifically, as shown in FIG. 3, if the selection signal for the specific terrain property received from the input unit 14 is A, B1, C1, C1-1, C1-1 to C1-3 except for A1 to A6 having the A terrain property. And C4 to C6. Reference numeral 301 denotes the position of the editing terminal.

Next, the editing mode determination unit 15 of the editing terminal 10 compares the route information on the numerical map with the movement route of the site (S203). To this end, it is preferable that the measurement unit 12 of the editing terminal 10 continuously measures the movement path of the editing terminal 10 being moved, and the measured movement path of the editing terminal 10 is displayed on the numerical map. . In addition, when the route information is displayed on the display unit 13, the movement route may be displayed by overlapping the route information.

That is, the editing mode determination unit 15 compares the route information on the numerical map with the moving path of the editing terminal 10 measured in real time by the measuring unit 12 (S203), and checks whether there is a match (S204). If there is a difference between the two paths, the editing mode to be executed is determined and this is displayed on the display unit. If there is no difference between the two paths, the editing process is terminated without editing the path information.

If there is a difference between the route information on the digital map and the movement route of the editing terminal, the editing unit 16 edits the digital map according to the determination result of the editing mode determining unit 15 (S205). That is, the editing unit 16 merges, divides, or modifies the polygons on the numerical map according to the determination of the editing mode determination unit 15 to edit the route information.

Specifically, the editing unit 16 compares the route information on the digital map with the movement route of the editing terminal, and if the route that is not via the editing terminal 10 is moved among the route information on the digital map, the route area is not routed. After extracting and outputting the extracted path region on the display unit (S206), the polygon attribute information processing unit 17 deletes boundary attribute information of the polyline of the polygon including the extracted path region (S207), and the editing unit 16 Merging each polygon (S208).

More specifically, in step S207, the polygon attribute information processing unit 17 may delete the polyline of the polygon selected by the input unit 14, and outputs a boundary attribute information deletion confirmation message to the display unit 13 for this purpose. The polyline is automatically deleted when a signal is received from the device confirming the deletion.

In addition, in operation S208, the editing unit 16 may merge the area selected by the input unit 14, output a merge confirmation message to the display unit 13, and automatically input a signal to approve the merge from the input unit 14. Can be merged. This can be represented as shown in FIG. 4. If the editing terminal 10 does not pass through the C1-1 path, the editing unit 16 extracts and displays the areas A1 and A2, which are areas including C1-1, to be prominently displayed. (Eg color changes, highlights, etc.). Thereafter, the editing unit 16 receives a selection signal for A1 and A2 from the input unit 14, and when receiving a signal for merging, merges the areas A1 and A2 to be represented as A1 (2). In addition, when the merge confirmation message "Are you merging A1 and A2?" Is displayed on the display unit 13 and the "confirmation", that is, the merge approval signal is transmitted from the input unit 14, the edit unit 16 is displayed. ) May be represented as A1 (2) on the display unit 13 by merging A1 and A2.

In addition, when the editing unit 16 compares the route information on the digital map with the movement route of the editing terminal 10 (S203), if there is a new route that is not included in the route information on the digital map among the movement routes via the editing terminal. After extracting the new diesel oil region, and displaying the extracted new diesel oil region on the display unit 13 (S209), the polygon attribute information processing unit 17 adds and attaches boundary attribute information to the polygon including the extracted new path. In operation S210, the editing unit 16 divides the polygon based on the movement path in operation S211.

More specifically, in operation S210, the polygon attribute information processing unit 17 may add new boundary attribute information to the area selected by the input unit 14, and outputs the attribute information addition confirmation message to the display unit 13, thereby inputting the input unit 14. When a signal to approve the addition is inputted from the parentheses, attribute information can be automatically added to the polygon and attached.

In addition, in operation S211, the editing unit 16 may divide the area selected by the input unit 14, output a division confirmation message to the display unit 13, and automatically input a signal for approving the division from the input unit 14. Can be divided This can be represented as shown in FIG. 5. If the editing terminal 10 has passed a new path across A4, the editing unit 16 markedly displays A4 where a new path has been created.

Thereafter, the editing unit 16 receives the selection signal for A4 from the input unit 14 and, when receiving the division signal, divides A4 into A4-1 and A4-2 based on the new movement path (reference number 302). Can be. In addition, the division confirmation message "Do you want to divide A4 into A4-1 and A4-2?" Is displayed on the display unit 13, and the confirmation confirmation, i.e., the division approval signal is inputted from the input unit 14 to the displayed division confirmation message. When transmitted, the editing unit 16 may divide A4 into A4-1 and A4-2 and display it on the display unit 13. In this case, the editing unit 16 may name the reference number 302 C1-3-1. In the embodiment of the present invention, the reference numeral 302 is named C1-3-1, and the area where A4 is divided is named A4-1, A4-2, but various modifications are possible according to the user's preference. .

In addition, the editing unit 16 compares the route information on the digital map with the movement route of the editing terminal (S203), and if the accuracy of the movement route of the editing terminal 10 is less than the threshold, the polygon of the area including the route information on the numeric map is selected. Output to the display unit 13 (S212), the polygon attribute information processing unit 17 maintains the boundary attribute information of the polylines included in the polygon (S213), the editing unit 16 includes the movement path of the editing terminal 10 The polygon is corrected to the polygon of the region (S214). Here, the threshold value can be arbitrarily adjusted by the setter, but is preferably set to 0.8 to 0.9.

The accuracy of the movement path may be calculated by comparing the storage path with the movement path and substituting the comparison result into Equation 1 below. That is, the total number of polygons (N) of the storage path and the moving path, the number of polygons whose paths match among the storage paths and the moving path (a), and the number of polygons whose paths do not coincide between the storage path and the moving path (d) The accuracy C can be calculated.

More specifically, in operation S214, the editing unit 16 may receive the coordinate values of specific nodes from the overlapping movement paths from the input unit 14 and connect the coordinate values of the input nodes to generate a polygon, and then modify the storage path. have.

In addition, the editing unit 16 may display coordinate values corresponding to specific nodes of the movement path, receive an error value from the input unit 14, and modify the storage path by adding the coordinate value and the error value to the displayed coordinate value. . The reason for receiving the error value is, for example, when the editing terminal 10 is mounted on the vehicle, since the coordinate value of the moving path of the vehicle movement and the coordinate value of the polygon classifying the real area may be different.

In addition, the editing unit 16 may output a correction confirmation message to the display unit 13, and when a signal for approving the correction is input from the input unit 14, the editing unit 16 may automatically correct the storage path with the coordinate value corresponding to the movement path. In the case of automatic modification, the storage path may be modified by generating polygons according to the interval of nodes preset by the user, and the storage path may be modified by generating polygons according to the interval of nodes input from the input unit 14. This may be represented as shown in FIG. 6, in which the A4 and C6 areas are markedly displayed when the editing terminal 10 passes through C6 and the accuracy of the movement path and the storage path is less than the threshold value.

Thereafter, the editing unit 16 may receive coordinate values of specific nodes from the input unit 14, generate polygons by connecting each node, and modify the storage path as shown by reference numeral 303. In addition, when the editing unit 16 receives the coordinate value of the movement path from the measuring unit 12 and displays it on the display unit 13, the editing unit 16 inputs a constant error value based on the coordinate value provided from the input unit 14. The storage path can be modified by generating coordinate values of nodes that can generate polygons by adding coordinate values and error values. Finally, on the display unit 13, a correction confirmation message " Do you want to modify A4 or C6? &Quot; is displayed, and when the confirmation confirmation message “OK”, that is, the correction approval signal is transmitted from the input unit 14, the editing unit ( 16 may be modified as A4 or C6 and displayed on the display unit as shown by reference numeral 303.

The editing unit 16 may repeatedly perform the editing process until the digital map editing completion signal is input from the input unit 14 (S215).

Then, when the edit completion signal is input, the editing unit 16 receives a selection signal for the specific region for changing the terrain attribute information from the numerical map from the input unit 14 (S216).

Then, when the terrain attribute information change signal is received from the input unit 14, the editing unit 16 changes the terrain attribute information of the specific region on the selected numerical map. In this case, the change of the terrain property information outputs a list of the terrain property information stored in the terrain property information 325 of the GIS server 30 to the display unit, and then receives an arbitrary terrain property information selection signal from the input unit 14. The terrain property information of the specific region may be changed by the selected terrain property information (S217). For example, in order to modify the terrain property information corresponding to the reference number 303 in the numerical map modified in FIG. 6, select the change of the terrain property information by selecting the reference number 303, and select D from the list of the displayed terrain property information. The editing unit 16 changes the reference numeral 303 to the D attribute. Subsequently, when the digital map editing is completed, the editing unit 16 transmits the edited digital map to the GIS server 30, and the GIS server 30 transmits the information included in the transmitted digital map to the digital map 321 and the coordinates, respectively. The information 322, the polygon attribute information 323, and the route information 324 are updated and stored, respectively (S218).
