Description

The present invention relates to a writing boundary specifying support computer device and a program thereof capable of scientifically and mechanically determining a writing boundary point when specifying a writing boundary of a land.
In the description of the present invention, when the term “tolerance” is used in a numerical sense, it means an absolute value of an allowable error that is added to or subtracted from a reference value. Similarly, the term “maximum tolerance” in “maximum tolerance point distance”, “maximum tolerance ground area”, etc. means a value obtained by adding the tolerance of that value to the reference value, and “minimum tolerance point”. The term “minimum tolerance” in “distance between” and “minimum tolerance area” means a value obtained by subtracting the tolerance of the value from a reference value. The term “accuracy category” means the accuracy category stipulated in Schedule 5 of the National Land Survey Law Enforcement Ordinance, and the term “predetermined accuracy category” means the accuracy required when creating various drawings to be used. Means a division.

  It is said that the border of land is based on public law and is not formed by the agreement of the parties, so when there is a dispute between the parties and it becomes necessary to specify the border, Maps that represent unknown brushstrokes (points), drawings that conform to the maps, and area survey maps that can be used to verify the boundaries (hereinafter collectively referred to as “reference maps”) Based on this, the brush boundary point will be restored to the site. However, the length of the land that is bounded by the reference map and the land that is bound by the border point claimed by the person concerned at the site (hereinafter referred to as the “point-to-point distance”). In addition, it is extremely difficult to restore while taking into account the land area, and if a border confirmation lawsuit is filed to solve the problem, not only will it require around five years and a large amount of money, but In many cases, it became a personality dispute among owners.

  On the other hand, the revised Real Estate Registration Law came into effect on January 20, 2006, and a system (Article 123 of the Law) for quickly identifying the writing circle was established. However, in reality, no systematic scientific method has been established for identifying brush boundaries. For this reason, in order to identify this difficult writing boundary point, the brush boundary specifying operator copies a reference map with a different scale on the tracing paper to the actual survey map actually surveyed in the field, Information that has been enlarged or reduced by a copier or rasterized by a scanner is transformed by a conversion means such as affine conversion, tin affine conversion, or Helmart conversion (hereinafter simply referred to as “graphic conversion”) and superimposed. While matching, the points within the tolerance (range) distance of the tolerance according to the accuracy classification of the reference data, which is the original data, were calculated several times, and after adjusting the area, it was considered appropriate. I have been working on identifying the brush world. However, such work has a lot of work loss, requires special experience and ability, and is unstable depending on the experience. It was difficult.

On the other hand, a system has been proposed that enables correction of polygon data of a reference map by using a positioning system at an witnessing site for determining a boundary line of a land (see, for example, Patent Document 1). . This system selects the desired writing point while displaying the polygon data figure of the reference map on the display of the notebook personal computer at the witnessing site to determine the writing field, and uses the real-time kinematic-global positioning system. The position of the place corresponding to the agreed brush boundary point is measured, and the position information is sent and confirmed as reference map data. However, even in this system, no solution has been proposed for the task of identifying where the writing world is set.

  The present invention is capable of scientifically and mechanically determining the brush cut point when specifying the brush border of the land, and providing the legal owner with a specific range of brush cut points that are legally possible. An object of the present invention is to provide a writing boundary specifying support computer device and a program thereof that can be visually presented and can perform the writing boundary specifying work more efficiently.

  According to the present invention, a writing boundary specifying support computer device includes an input means for inputting current state survey map data, reference map data, register area data, and other data of a land that needs to be specified, and an input current state survey Storage means for storing figure data, reference chart data, registry area data and other data, arithmetic processing means for performing various arithmetic processes, and output display means for displaying various information Prepare.

  The arithmetic processing means creates a reference map by polygonizing the reference map data of the storage means, creates a current survey map by polygonizing the current survey map data of the storage means, and presents the base writing point on the reference map layer Create a corrected reference map by transforming the reference figure by matching it to the corresponding base point of the survey map layer, and each maximum from the selected base point to the specified point The tolerance arc region is defined by a circle whose radius is the distance between the tolerance points, and the tolerance polygon region is defined by lines indicating the maximum and minimum tolerance areas of each land based on the register area data. Are stored in the storage means, and each figure and each region are processed as individual layers, and the required layers are individually or superposed on each other and displayed on the output display means.

  Further, the arithmetic processing means in the brush boundary specification support computer device according to the present invention defines step tolerance circles that define each accuracy range indicating the maximum tolerance position of the position of the brush boundary point to be determined determined by the predetermined accuracy classification. Then, it may be stored in the storage means.

  The writing boundary identification support program according to the present invention includes a procedure for inputting the current surveying map data, reference map data, and registry area data of the land requiring the boundary specification from the input means and storing them in the storage means, and the arithmetic processing means. The current survey map data and the reference map data stored in the storage means are created as polygons, and the current survey map layer and the reference map are created on each layer. Overlay the layers and display them on the output display means, and select the base writing point and the writing point to be specified, and the calculation processing means to match the base writing point on the reference map layer to the current survey map layer Selected by the calculation processing means and the procedure for creating a correction reference map on the correction reference map layer, which is formed by converting the reference figure into a figure that matches the base point Calculate the distance tolerance between the points on the reference map from each base point to the specified point based on the base point and the specified point. Each land based on the register area data by the procedure to create a tolerance arc area on the tolerance arc layer defined by a circle whose radius is the distance between each maximum tolerance point centered on the boundary point, and calculation processing means The area tolerance of the land is calculated, and the tolerance polygon area defined on the correction reference map by the lines indicating the maximum and minimum tolerance ground areas of each land is created on the tolerance polygon layer and specified by the output display means. In order to search for an appropriate position of the power stroke point, a computer is caused to execute a procedure for displaying a necessary layer in a superimposed manner.

  In addition, the writing boundary specification support program according to the present invention provides a reference from each base point writing point to the writing point to be specified based on the selected base point writing point and the writing point to be specified by the arithmetic processing means. Calculate the tolerance according to the default accuracy classification of the average value of the distance between points on the figure, and use the step tolerance circle with the tolerance of the average distance between the points as the radius around the selected base point You may further include the procedure created on a circle layer.

  According to the present invention, in the conventional method, every time a temporary writing boundary point is set, the work of examining and comparing the distance between the points, the land area, and the features of the current survey map, etc. has to be repeated. On the other hand, since the position where the writing point can exist is within the tolerance range defined by the tolerance arc region and the tolerance polygon region, and it can be considered by drawing a temporary writing point on the graphic with the mouse, In addition to being able to find a reasonable writing boundary point mechanically and quickly, in the unlikely event that a possible position is not defined by the tolerance arc area and tolerance polygon area, the level of available accuracy classification is estimated. On the contrary, by narrowing down the range that can be determined by the higher-order accuracy classification, it can be estimated that the accuracy of the reference diagram is created with higher accuracy. In addition, according to the present invention, it is possible to categorize the work process and generalize the work, and even in the work based on the same material, the dispute caused by each specific worker specifying a different writing point. Etc. can be avoided. In addition, since the maximum tolerance position of the position of the writing point to be specified can be indicated using the step tolerance circle, it is visually confirmed whether the position of the writing point to be specified is within the tolerance of the predetermined accuracy category. It can be easily confirmed.

  In the present invention, the writing point to be specified must be within the tolerance of the predetermined accuracy class of the distance between points of the reference map and within the tolerance of the default accuracy class of the land area. Furthermore, the brush point to be identified was conceived mainly in view of the fact that it must be within the tolerance range defined by the tolerance arc region and tolerance polygon region drawn in the current survey map. Is. The writing point to be specified satisfies the above three conditions, in addition to the above two conditions, which is within the maximum tolerance distance according to the accuracy classification of the average value of the distance between points on the reference diagram. preferable.

《Brush boundary identification support computer device》
As shown in FIG. 1, the brush boundary specification support computer device 10 according to the embodiment of the present invention includes a current state survey map data D1, basic map data D2, registry area data D3, and various other types of land that require a brush boundary specification. A storage device 11 for storing the data, an arithmetic processing device 12 for performing various arithmetic processes, an input device 13 such as a keyboard, a mouse, and a scanner, and an output display device 14 such as a display and a printer. ing.

  The current survey map data D1 and the reference map data D2 are usually preferably stored in the storage device 11 as vector data because of the applicability of the polygonized data, particularly the ease of deformation. However, it is possible to store the raster data in the storage device 11 by providing a Lasbeck conversion means (not shown) for converting the raster data into vector data.

  The arithmetic processing unit 12 polygonizes the current survey map data D1 and the reference map data D2 to create a current survey map G (see FIG. 2) and a reference map K (see FIG. 3), respectively, and the current survey map layer L1 and Each is displayed on the reference diagram layer L2 and stored in the storage device 11. As shown in FIGS. 4 and 5, the arithmetic processing unit 12 also converts a plurality of base point stroke points (in the case of illustration, Pk 1, Pk 2, Pk 3) on the reference map K to a plurality of corresponding base points on the current surveying chart G. The reference diagram K is converted into a figure by matching with the writing boundary points (Pg1, Pg2, Pg3) to create a correction reference diagram H, which is displayed on the correction reference diagram layer L3 and stored in the storage device 11. Here, the base writing point (Pg1, Pg2, Pg3) on the current surveying chart G and the base writing point (Pk1, Pk2, Pk3) on the reference chart K are between the current surveying chart G and the reference chart K. Thus, the points are determined to be in positions corresponding to each other. The point indicated by the reference sign Qg is a writing boundary point that should be specified to specify the writing boundary on the current survey map G, and the reference sign Qk is a writing boundary point that should be specified on the reference chart K. The reference symbol Qh is a necessary writing point to be specified on the correction reference diagram H.

  The arithmetic processing unit 12 processes various data as will be described later, thereby defining a tolerance arc region A1, a tolerance polygon region A2, and step tolerance circles E1, E2,..., And a tolerance arc layer L4, tolerances The information is displayed on the polygon layer L5 and the step tolerance circle layer L6, and stored in the storage device 11.

  The method of defining the tolerance arc region A1 should first be specified as each reference writing boundary point Pk1, Pk2, Pk3 in the reference map K by the arithmetic processing unit 12 based on the reference map data D2 stored in the storage device 11. The distances between the maximum and minimum tolerance points R1max and R1min; R2max and R2min; R3max and R3min are calculated. Next, as shown in FIG. 6, the distance between the maximum and minimum tolerance points R1max and R1min; R2max and R2min; R3max centered on each reference writing boundary point (Ph1, Ph2, Ph3 in the case of illustration) in the correction reference diagram H; And R3min are drawn with maximum and minimum tolerance circles C1max and C1min; C2max and C2min; C3max and C3min, respectively. A region where the regions located between the respective maximum and minimum tolerance circles overlap each other is a tolerance arc region A1.

  As shown in FIG. 7, the method for defining the tolerance polygonal area A2 is based on the reference map data D2 stored in the storage device 11, and each of the two adjacent to the stroke point Qh to be specified in the correction reference map H. While calculating the distance between the reference brush boundary points Ph1 and Ph2; Ph2 and Ph3 (line segments B1 and B2) by the arithmetic processing unit 12, the land area tolerance of each land is calculated based on the register area data D3 of the storage unit 11. calculate. Next, based on the calculated land area tolerance of each land, the maximum and minimum tolerance heights H1max and H1min; H2max and H2min from the line segments B1 and B2 to the border point Qh satisfying the land area of each land are calculated. A region surrounded by lines S1max and S1min; S2max and S2min indicating the positions of the maximum and minimum tolerance heights H1max and H1min; H2max and H2min, respectively, is a tolerance polygon region A2.

  The method of defining the step tolerance circles (E1 and E2 in the case of illustration) is based on the reference map data D2 stored in the storage device 11, and is calculated by the arithmetic processing unit 12 to each reference writing boundary point Pk1, Pk2 in the reference map K. The average value of the distance between Pk3 and the writing point Qk to be specified is calculated, and the tolerance according to the predetermined accuracy classification of the calculated average value is calculated. Next, as shown in FIG. 8, a circle is drawn with the radius of the tolerance of the average point distance centered on the writing point Qh to be specified in the correction reference diagram H. This circle is a step tolerance circle (E1, E2) indicating the maximum tolerance position in each accuracy division (in the case of illustration, two accuracy divisions) of the position of the writing boundary point to be specified.

《Brush boundary identification support program》
The writing boundary identification support computer device 10 of the present invention is basically operated by a writing boundary identification support program. As shown in FIG. 9, the writing boundary specifying support program first inputs the current surveying map data D1, the reference map data D2, and the register area data D3 of the land that requires the writing boundary specification by using the input device 13, and the storage device. 11 is stored (step 1). The input of this data, particularly the input of the reference map data D2 and the current surveying map data D1, varies depending on how the original data can be obtained. For example, in the case of the most basic data written on paper, it is read by a scanner, and the read data is subjected to a Lasbeck conversion to be stored in the storage device 11 as vector data. Here, the current survey map data D1 includes information indicating the brushstroke of the land as well as things in the place to be identified, for example, rocks and rocks, etc. Preferably, the location information of the point to be claimed is included.

  The current processing survey map data D1 and the reference map data D2 stored in the storage device 11 are respectively called by the arithmetic processing unit 12 (step 2), and are converted into polygons to generate the current survey map G and the reference map K. The current survey map layer L1 (FIG. 2) and reference diagram layer L2 (FIG. 3) are recorded in the storage device 11 (step 3). The created current survey map layer L1 and reference map layer L2 are displayed on the output display device 14 so as to overlap each other as shown in FIG. 4 (step 4). The writing boundary points (in the case of illustration, three writing boundary points P1k to P3k) and the writing boundary point Qk to be specified are selected (step 5). The writing point Qk to be specified is a writing point that is located at or near the place in question between the parties, and the base writing point is, as a whole, an overlaid current survey map G and reference map. A writing boundary point that is a position corresponding to each other (essentially the same position) is selected from K. In selecting the writing boundary point, it is preferable to change the current survey map G and / or the reference map K by graphic transformation so that both writing boundary points are located at the same position as much as possible.

  When the base writing point P1k, P1g; P2k, P2g; P3k, P3g and the writing point Qk, Qg to be specified are selected, the basic writing point P1k on the reference diagram K is selected as shown in FIG. , P2k, P3k are matched with the corresponding base point penetration points P1g, P2g, P3g on the current surveying chart G, and the reference chart K is converted into a current state as shown in FIG. The shape is adjusted in accordance with the survey map G (step 6), and the generated correction reference diagram H is drawn on the correction reference diagram layer L3 and stored in the storage device 11 (step 7).

  Based on the reference map data D2 stored in the storage device 11, the distances from the base writing point P1k to P3k on the reference map K to the writing point Qk to be specified are calculated. By adding or subtracting the tolerance determined by the predetermined accuracy classification that created the reference map data D2 to be used to the calculated distance, the maximum and minimum tolerance point distances R1max, R1min; R2max, R2min; R3max, R3min 6 (step 8), and as shown in FIG. 6, the maximum and minimum tolerance point-to-point distances R1max, R1min; R2max, R2min; R3max centered on each of the reference brush point P1h to P3h on the correction reference diagram H , R3min, and the maximum and minimum tolerance circles C1max, C1min; C2max, C2min; C3max, C3min are drawn respectively. A region where the regions located between the maximum and minimum tolerance circles C1max, C1min; C2max, C2min; C3max, C3min drawn in this way is the tolerance arc region A1. This tolerance arc region A1 is created and recorded on the tolerance arc layer L4 (step 9). Here, if the tolerance arc area A1 cannot be defined because the areas between the respective maximum and minimum tolerance circles do not overlap each other, the area surrounded by the maximum tolerance circles C1max, C2max, C3max is defined as the tolerance arc area A1. Available. Furthermore, when the region surrounded by the maximum tolerance circles C1max, C2max, and C3max cannot be defined, the tolerance arc region A1 is defined by applying a larger tolerance accuracy category.

  On the other hand, the registered area data D3 of each land stored in the storage device 11 is called, and the maximum and minimum tolerance ground areas in the predetermined accuracy classification are calculated from the called registered area data D3, respectively, while the current surveying In FIG. G (see FIG. 2), it is formed by the writing point Qg to be specified and two reference writing points adjacent thereto (in the case of FIG. 7, the basic writing points P1g, P2g; P2g, P3g). Area of the remaining portions (triangles P4g-P1g-P2g and triangles P5g-P2g-P3g) except for the two triangles (triangles Qg-P1g-P2g and triangles Qg-P2g-P3g). Next, the maximum and minimum tolerance ground areas of the triangle Qg-P1g-P2g and the triangle Qg-P2g-P3g of each land are respectively calculated by subtracting the remaining areas calculated from the maximum and minimum tolerance ground areas of each land. Along with (Step 10), the lengths of the line segment B1 between the base point writing points P1g and P2g and the line point B2 between the base point writing points P2g and P3g in the correction reference diagram H are calculated (base point writing point P1g, P2g and P3g are in the same position as the base brush point P1h, P2h, and P3h, respectively.) The maximum and minimum tolerances of triangles Qg-P1g-P2g and triangles Qg-P2g-P3g thus calculated are divided by the lengths of line segment B1 and line segment B2, thereby obtaining the maximum and minimum values of the respective triangles. Tolerance heights H1max, H1min; H2max, H2min are calculated (step 11). As shown in FIG. 7, the regions surrounded by lines S1max and S1min; S2max and S2min indicating the positions of the maximum and minimum tolerance heights H1max and H1min; H2max and H2min, respectively, are tolerance polygon regions A2. The square area A2 is created on the tolerance polygon layer L5 and recorded in the storage device 11 (step 12).

  Further, based on the reference map data D2 stored in the storage device 11, an average value of the distances from the base writing point P1k, P2k, P3k to the writing point Qk to be specified is calculated, and the average value is calculated. A tolerance corresponding to a predetermined accuracy category is calculated (step 13). Next, by drawing a circle having a radius of the mean value tolerance centered on the writing boundary point Qh to be specified in the correction reference diagram H, as shown in FIG. Step tolerance circles E1, E2) are defined, and the step tolerance circles E1, E2 are drawn on the step tolerance circle layer L6 and stored in the storage device 11 (step 14).

  When the tolerance arc layer L4, the tolerance polygon layer L5, and the step tolerance circle layer L6 are prepared, as shown in FIG. 10, the tolerance arc layer L4 and the tolerance polygon layer L5 are overlapped (step 15), thereby the tolerance. A specific allowable area A3 is defined in which the arc area A1 and the tolerance polygon area A2 overlap each other. The specific permissible area A3 means an area where the writing point to be specified is legally movable, and the current survey map layer L1, the reference map layer L2, and the correction reference map layer L3 are added to this as necessary. Overwriting, the current feature, the complainant, the opponent, and the points claimed by the parties concerned are selected to select the writing boundary point to be specified, and the writing boundary specification is performed (step 16). When the writing point is specified, the step tolerance circle layer L6 is further overlapped, and it is confirmed whether the specified writing point is at an appropriate position in terms of accuracy classification (step 17).

  More practically, the brush boundary specification work is performed by moving the brush boundary point Qh to be specified within the allowable area A3 on the correction reference map layer L3 displayed on the display (output display device), and This is performed by determining a writing boundary point Qh to be specified that can be agreed between the two parties in consideration of the occupation state. At this time, the numerical value of the distance between each point and the area of each land at the moved brush point to be identified, the layer at which the brush point is identified, It is desirable to display attributes such as whether there are any. When the tolerance arc area A1, the tolerance polygon area A2, and the specific allowable area A3 cannot be created, or when the writing point that can be agreed by both parties is not located within the specific allowable area A3, the areas A1 to A3 can be created. Until the agreed brush point is located in the specific allowable area A3, the distance between the tolerance points and / or the accuracy classification of the tolerance area is lowered, and the above operation is repeated to appropriately specify Specify the position of the writing boundary point.
