A Method of Finding the Four Locations of Parcel Using Boundary Points and 45° Circumscribed Rectangle

Abstract

The invention discloses a method for searching for four locations of a parcel by using a boundary point and a 45° circumscribed rectangle. Based on the parcel, find the four places closest to the southwest, southeast, northeast and northwest of the parcel through the 45° departing circumscribed rectangle. The boundary point of the direction, the four boundary points cut the boundary of the parcel, and constitute the four boundaries of the east, west, south, and north. Based on the adjacency relationship of the adjacent parcels, the topology search can be more reasonable and complete. Four to attribute. The present invention not only makes up for the deficiencies of the existing methods, replaces manual discrimination, greatly improves the efficiency of the four-distance search of parcels, saves time and labor costs, and the four-distance search results have good accuracy, fully satisfying the need to confirm land rights requirements.

Description

technical field [0001] The present invention relates to the technical field of basic geographic information data processing. Specifically, it is a method for searching four-distance parcels by using boundary points and 45° circumscribed rectangles. The method can be applied to the internal data processing process in the later stage of land right confirmation Especially the filling process of the four attributes. Background technique [0002] A parcel of land refers to a closed plot composed of ownership boundaries, which is a piece of land with definite boundaries and definite ownership on the surface of the earth. Boundary point refers to the turning point of the parcel ownership boundary, that is, the inflection point. It is an important symbol to demarcate the ownership boundary of the parcel. The four directions of a parcel of land refer to the boundary line between the four directions of a parcel of land and the adjacent land. Generally, fill in the names of the adjac...

AI Technical Summary

Problems solved by technology

[0003] Most of the existing land parcel search methods are manual identification. Manually filling the attributes of the four destinations into the attribute table is a heavy workload and inefficient

There are also ways to use positive circumscribed rectangle buffering and azimuth search, but the calculation is relatively cumbersome, and the accuracy of judging adjacent parcels with some special shapes is not high
