Abstract

The invention provides a two-stage land boundary change area automatic construction method and system. According to the invention, a plurality of directed closed coils are arranged on the land boundary line in two periods; direction defining method, the land boundary lines are mutually cut into a plurality of directed broken line sections; an automatic construction algorithm for the land boundaryline interval transition area in the two periods is provided, an expansion type area and a retraction type area can be rapidly and accurately constructed and marked according to the land boundary lines in the two periods, and a certain auxiliary effect is achieved for analysis of the change rule of the land boundary lines and formulation of related prevention and control measures. By processing the actual data, the generated transition area is consistent with the actual situation, and the correctness of the algorithm in the embodiment of the invention is explained to a certain extent.

Description

technical field [0001] The invention relates to the technical field of three-dimensional geological modeling, in particular to a method and system for automatically constructing two-period land boundary change regions. Background technique [0002] Land boundary changes have had and will continue to have a non-negligible impact on urban construction, industrial and agricultural production, and people's lives. Therefore, it is necessary to strengthen the study of land boundary changes and further grasp the laws of land boundary changes, so as to scientifically and rationally deploy cities and economic construction. , and receive twice the result with half the effort. [0003] Currently, research on land boundaries mainly focuses on: [0004] The extraction method of the land boundary outline and related parameters, the automatic processing algorithm of the land boundary shape, and the summary of the change of the land boundary in a certain area, among which the determination...
