Description

Method and device for automatic fine-tuning of parcel/polygon boundary points

The present invention relates to a technology for fine-tuning boundary points of parcels including polygons, and more particularly, to automatically fine-tune the boundary points of a plurality of parcels or polygons collectively to conform to area conditions to reduce area errors. It relates to a fine-tuning method and apparatus.

In the cadastral resurvey project, cadastral resurvey surveys that repair cadastral unsuitable lands and world geodetic system conversions of boundary point coordinate registration areas commonly cause minute area errors due to changes in coordinate units related to the number of decimal places. When the coordinate unit is changed, the area error does not occur or is insignificant for small area parcels, but the error intensifies for parcels with a certain area or more.

In order to remove the fine area change due to the change of the coordinate unit, the user directly selected the boundary points and tried to fine-tune the boundary, but it was inefficient and inaccurate because it took too much time and cost.

Due to this problem, in the practice of cadastral resurvey, 'Korea Land and Geospatial Information Corporation Spatial Data Research Institute' is using boundary fine adjustment SW to adjust, but the driving method is a method in which users must select parcels and adjacent boundary points directly. It takes a lot of time to adjust hundreds to tens of thousands of lots or polygons one by one, and when adjusting one by one, the area of the entire lot is pushed back, which may make it impossible to adjust in the subordinated lots. At this time, the order of adjustment of the lot has to be changed and adjusted again from the beginning, which reduces the efficiency of the work. In addition, the task of converting the boundary point coordinate registration area into the world geodetic system requires a plan to efficiently solve this problem because the area error is aggravated by the change of the coordinate unit to the minute area error during the coordinate conversion.

FIG. 3 is a diagram explaining the functional configuration of the automatic fine-tuning device in FIG. 1 .

Referring to FIG. 3 , the automatic fine adjustment device 130 includes a coordinate unit changing unit 310, a parcel order designating unit 330, a boundary fine adjustment execution unit 350, a coordinate fixing unit 370, and a control unit 390. can include

The coordinate unit changing unit 310 can change the unit of coordinates of the parcel or polygon boundary points and select area conditions. The coordinate unit changing unit 310 may change the precision of boundary point coordinates of parcels or polygons from 0.001 m to 0.01 m as a preliminary preparation step before fine adjustment of the boundary point is performed. The coordinate unit changing unit 310 may select whether to set the area condition to the area before the coordinate unit change or to the large area registered in the study. The coordinate unit changing unit 310 may select an area condition according to the area registered in the cadastral study since the area before the coordinate unit change is used as the standard in the case of cadastral resurvey survey and the area registered in the cadastral study is used as the standard in the case of world geodetic system conversion. The coordinate unit changing unit 310 may select an area specified by a user as the area condition.

The parcel order designation unit 330 may determine the adjustment order of a plurality of parcels. The parcel order designation unit 330 may automatically or manually designate an adjustment order among a plurality of parcels. The parcel order designation unit 330 may designate an adjustment order for a plurality of parcels based on parcel information including at least one of a lot number, location, area, distribution, point-to-point distance, and area error. In one embodiment, the lot order assigning unit 330 may set the order so that the adjustment is performed in the order of lot number, and may change the order to re-designate the adjustment order when the adjustment fails. In one embodiment, the parcel order assigning unit 330 may first adjust the parcels in the central location and determine the parcels in the periphery later. If the adjustment is performed from the outer parcels and the central parcels are determined later, the adjustment may fail because the space for the area error to be erased disappears in the central parcels. The reason that the parcels on the outskirts need to be adjusted later is that there is no boundary line meeting other parcels on the outskirts, so fine area errors can be eliminated smoothly. In one embodiment, the parcel order designation unit 330 may adjust parcels with a small area first when a parcel with a large area and a parcel with a small area are adjacent to each other, and set the author with a large area later. This means that if a large-area lot is adjusted first, a large area error is propagated from the beginning and transferred to a small-area lot later, making it impossible to eliminate the area error. In one embodiment, the lot order designation unit 330 may determine the adjustment order by grouping and separating the parcels, rather than determining the adjustment order of parcels in units of the entire area. This may fail because errors accumulate during straight-line direction sequence adjustment and exceed the limit of the adjustment index range at some point.

In one embodiment, the lot order designation unit 330 may designate an adjustment order according to the distribution of lots in each zone. For example, if the parcel distribution is distributed in a long north-south direction, the order can be set in the direction from top to bottom or from bottom to top. At this time, if adjustment fails in some parcels and a disconnection occurs, the order to be adjusted while moving by region can be determined. can If the parcels are distributed in the east-west direction, the parcel adjustment sequence route can be set so that it starts at the northeast point, passes through the west, and proceeds to the southeast. If the parcels are distributed in the northeast to southwest direction, the parcel adjustment order path can be determined so that the order of adjustment proceeds from north to east-west and then proceeds from south to center. If parcels are distributed in the east-west direction, the adjustment order can be set in the east-west-north-south direction starting from the central parcel. The parcel order designation unit 330 may determine the adjustment order according to the distribution direction of parcels for each zone, and may change and readjust the adjustment order when the adjustment fails while automatically fine-adjusting the boundary points in order. Here, the lot order designation unit 330 succeeds in automatic fine-tuning of the boundary points by setting the order in the direction of progress while rotating in all directions from the center since area error propagation is more sensitive in the case of areas with a large area scale than areas with a small area scale. to increase your chances.

In one embodiment, the parcel order assigning unit 330 may prioritize and adjust parcels having a long distance between boundary points or parcels having a large area error. When adjusting parcels with a long distance between boundary points or parcels with a large area error, there is a risk of adjustment failure due to the accumulated area error.

In one embodiment, the parcel order designation unit 330 may designate an adjustment order by excluding area conditions of some parcels. For example, only boundary points can be reflected when adjusting adjacent parcels except for the area conditions of long parcels such as roads or rivers. Since there are many parcels adjacent to roads or rivers, an exception can be made to the adjustment order considering this.

The boundary fine-adjustment executing unit 350 may select a boundary fine-adjustment method and execute boundary fine-adjustment according to the selected boundary fine-adjustment method in the order of adjustment of the lot in the corresponding area.

Boundary fine adjustment refers to adjusting the boundary point until the desired area coincides with moving the boundary point from the original location at regular intervals in order to match the actual area of the lot or polygon with the desired area. The boundary fine adjustment direction may include a clockwise direction, a counterclockwise direction, a random direction, or a rule determined by a user.

4 is a diagram for explaining the basic principle of boundary fine adjustment, and is an example of adjusting boundary points clockwise (rightward direction).

Referring to FIG. 4 , when trying to adjust a boundary point whose coordinate unit is changed to 0.01 m, boundary point number 1 to be adjusted is the original position and positions 2 to 9 are within the adjustable range of 1 cm. Here, the adjustment range is 1 cm, but it is not limited to this, and the unit and interval can be varied. Considering that the coordinate unit of boundary point 1 is 0.01m, it can be adjusted in units of 1cm. At this time, the area at 0.001m before the coordinate unit is changed or another area of fine difference desired by the user can be adjusted from 1 to 9. It is to adjust the boundary points in the order of the position of the burn. If the coordinates of the boundary points of the parcel are changed from 0.001m unit to 0.01m unit, all boundary points are checked to see if the area is identical at position 1 by default. If the areas match at position 1, there is no need to adjust them. If the areas do not match, move one boundary point to position 2, check the areas, fix them if they match, and adjust to position 3 if they don't match. Adjust the remaining positions 4 to 9 in the same way until the areas match.

However, since there is a limit to satisfying the area condition with only one boundary point, fine adjustment of multiple boundary points is required. To fine-tune multiple boundary points is to expand and apply the basic principle of fine-tuning that the user selects when there are many boundary points. In other words, it is a method of selecting and adjusting several boundary points, not just one point, among the boundary points of the lot that can be adjusted.

5 is a diagram for explaining coordinate adjustment of multiple boundary points, and is an example of adjusting a plurality of boundary points in a polygon in a clockwise direction (right direction).

Referring to FIG. 5, when four boundary points are selected within the range of 1 cm, 6,561 (9 ⁴ = 6,561) cases are calculated when adjusting boundary points 1 to 4. The more adjustment points, the higher the probability of area matching. In particular, it can be effectively applied in cases where the number of boundary points is large and the amount of change in area is relatively large, such as a ditch or road.

In addition, since the area condition may fail when the boundary point is adjusted only within the range of 1 cm, the probability of area matching can be increased by adjusting the boundary by extending this range. For example, if the adjustment range of one boundary point is expanded to 2 cm, adjustment is possible in 25 cases, and if two points are adjusted, 25 ² = 625 cases can be derived. If it is enlarged to 3 cm, it can be adjusted in 49 cases, and when adjusting 2 points, 49 ² = 2,401 cases occur.

Returning to FIG. 3 again, the boundary fine-adjustment executing unit 350 may perform boundary fine-adjustment by choosing between a total method in which a plurality of boundary points are adjusted through the entire index and a section method in which indexes are adjusted based on sections. In one embodiment, the boundary fine-adjustment execution unit 350 may distinguish between the total method and the section method according to whether or not the adjustment range is separated by section, and '1 fill' and '2+1' depending on the number of lots in consideration of the area condition. It can be classified as 'fill' adjustment method.

When the boundary fine adjustment unit 350 executes the boundary fine adjustment in the enumeration method, it may select a plurality of boundary points and adjust all of the selected boundary points as in the 'multiple boundary point coordinate adjustment' method described in FIG. 5 . In one embodiment, the boundary fine-adjustment unit 350 expands the adjustment range to 7 cm when executing boundary fine-adjustment in a total method, thereby increasing the area matching probability. In the boundary fine adjustment unit 350, the number of indexes capable of adjusting one boundary point may be up to 225 within a range of 7 cm. Here, the index means the order to be adjusted in the order determined within a certain range when adjusting the boundary points by simulation in boundary fine adjustment. When the maximum adjustment range is expanded to 7 cm and indexes are sequentially assigned in a clockwise direction, the boundary fine adjustment index can be represented as shown in FIG. 6 .

6 is a chart showing boundary refinement indices.

Referring to FIG. 6 , the boundary fine adjustment index represents a case in which the maximum adjustment range is enlarged to 7 cm and the adjustment order is determined sequentially in a clockwise direction. Here, the reason for setting the range of adjustment to 7 cm is that in Article 7 (Determination of Survey Results of Cadastral Resurvey) of the Enforcement Rules of the Special Act on Cadastral Resurvey (enacted on October 19, 2017), the range of connection intersection of inspection for boundary points is ±0.07m. The range was determined based on this. Although the adjustment range can be expanded to a greater extent than this, it takes a lot of time during adjustment simulation, and the adjustment amount of the boundary point may increase, so that the original position may be greatly different.

Returning to FIG. 3 again, the boundary fine-adjustment execution unit 350 may sequentially adjust boundary points through a transfer method of adjusting a plurality of boundary points while going through the entire index. The number of boundary points and the number of cases according to the adjustment range in the transfer method are shown in Table 1 below.

[Table 1]

As shown in Table 1, as the adjustment range increases and the number of boundary points to be adjusted increases, the number of cases that can be adjusted increases exponentially. Therefore, if adjustment fails within a narrow range, the possibility of finding a location that meets the area condition can be increased by expanding the range.

For example, if the boundary adjustment range of 1 point is 7 cm (7 steps), the number of cases is calculated as 225, and the number of cases increases as the number of boundary points to be adjusted increases. When they coincide, the position of the boundary point is determined with the corresponding index and the adjustment simulation is stopped.

In an embodiment, the boundary fine-adjustment execution unit 350 may execute boundary fine-adjustment in a section manner in which a different index is set for each adjustment range section in order to reduce the adjustment time. Here, the index for each section may be set by the user. The section method is a method of adjusting based on the index for each section, and can reduce the deviation of the adjustment amount between boundary points and reduce the time cost according to simulation by separating the adjustment range of the index so that it is not cross-adjusted with the lower step. For example, if the adjustment range is 2 cm and the target point for adjustment is 2 points, after performing the simulation for each of the two points in the 1 cm range, when the adjustment range of one point is expanded to 2 cm, the other point excludes the index corresponding to 1 cm. It is applied as an index in the range of 2 cm.

Table 2 below summarizes the indexes for each adjustment range of the total method and the section method.

[Table 2]

In one embodiment, the boundary fine-adjustment executing unit 350 may perform simulation by selecting a 1-fill or 2+1-fill method from total number or section method according to the number of parcels in consideration of area conditions during boundary fine-adjustment. Here, the boundary fine-adjustment unit 350 basically adjusts by two fills, but if it fails, it can adjust by one fill only for the corresponding parcel.

The boundary fine-adjustment execution unit 350 may perform boundary fine-adjustment after changing the order of parcels differently again if the area condition does not match even one parcel during the boundary fine-adjustment. The boundary fine-adjustment execution unit 350 may adjust a plurality of boundary points according to the index, and if the boundary point to be adjusted meets the condition of the adjustment range, the index is adjusted. Let the adjustment begin. Since the index number change rules are set in this way, the position of the boundary point can be automatically adjusted. The boundary fine-adjustment execution unit 350 adjusts adjacent boundary points according to the index, temporarily reflects the changed coordinates on the parcel, rounds them up to the area unit of the parcel, and adjusts them. The boundary fine-adjustment execution unit 350 checks whether the parcel to which the adjusted coordinates are reflected meets the area condition, and continuously performs boundary fine-adjustment simulation until it meets the area condition. That is, the boundary fine-adjustment execution unit 350 continues the process of adjusting the boundary point of the parcel to be adjusted according to the index according to the section or total method and checking whether or not it meets the area condition again.

The coordinate fixing unit 370 may fix the coordinates of the parcel if the parcel to which the coordinates of the boundary fine-adjusted are reflected meets the area condition, and set the parcel as the adjusted parcel. The coordinate fixing unit 370 can check the corresponding lot in the boundary point list of the entire area for the parcel for which adjustment has been completed, fix the location of the boundary point, and exclude it from the adjustment target. Here, the entire zone boundary point list may correspond to a list separately configured to reflect in real time to adjacent parcels when adjusting the boundary points of adjacent parcels.

The control unit 390 controls the overall operation of the boundary fine-adjustment device 130, and includes the coordinate unit changing unit 310, the lot order designation unit 330, the boundary fine-adjustment execution unit 350, and the coordinate fixing unit 370. It can manage control flow or data flow between

7 is a flowchart illustrating the process of automatic fine-tuning of parcel/polygon boundary points according to the present invention.

Referring to FIG. 7 , the automatic fine-tuning device 130 may change the unit of coordinates of parcels or polygon boundary points through the coordinate unit changing unit 310 (step S710). In addition, the automatic fine-tuning device 130 may select whether to set the area condition to the area before the coordinate unit change or to the large area registered in the study through the coordinate unit changing unit 310 (steps S720 and S730). The coordinate unit changing unit 310 sets the area condition to the area before the coordinate unit change in the case of the fine adjustment of the boundary of the cadastral resurvey survey area, and designates the area condition as the area registered in the cadastral study in the case of the fine adjustment of the boundary of the world geodetic system conversion area. can The coordinate unit changing unit 310 may set the area condition to an area designated by a user.

In addition, the automatic fine-tuning device 130 may determine the order of parcels through the parcel order assigning unit 330 (step S740). In addition, the automatic fine-adjustment apparatus 130 may select a boundary fine-adjustment method through the boundary fine-adjustment execution unit 350 and execute boundary fine-adjustment according to the selected method (step S750).

In addition, the automatic fine-adjustment device 130 may perform boundary fine-adjustment after changing the order of parcels differently again if the area condition does not match even if the area condition is 1 lot during the boundary fine-adjustment through the boundary fine-adjustment execution unit 350 (step S760). In addition, the automatic fine-adjustment device 130 may complete boundary fine-adjustment collectively by storing parcel coordinates through the coordinate fixing unit 370 when the area conditions of all parcels or polygons are perfectly matched (step S770). ).

FIG. 8 is an exemplary diagram illustrating a case of fine-adjusting boundary points in units of 1 parcel, and FIG. 9 is an exemplary diagram illustrating a case of fine-adjusting boundary points in a mixed unit of 2+1 parcels.

Referring to FIGS. 8 and 9 , the automatic fine-adjustment device 130 may perform different adjustment methods according to the number of parcels considering the area condition when fine-tuning the boundary. As shown in FIG. 8, the boundary points inherent in the corresponding lot or polygon can be simulated to be adjusted in total or in a section manner by considering the area condition in units of 1 fill, and as shown in FIG. can If the area of 2 lots fails to be adjusted at the same time when finely adjusting the boundary, it can be adjusted in units of 1 lot only for the relevant lot.

A method and apparatus for automatically fine-adjusting parcel/polygon boundary points according to an embodiment reduce the adjustment time by automatically fine-tuning a plurality of parcel boundary points in a batch until they match a desired area targeting a parcel or polygon on a cadastral map. Alternatively, it is possible to reduce the coordinate area of the polygon and the area error on the study, and improve the work efficiency of cadastral resurvey or world geodetic system conversion of cadastral maps.
