Abstract

The invention discloses a method for subtly organizing regular geographic entity space geometry data. Firstly, geometrical information of a regular geographic entity and parts of the regular geographic entity is collected, secondly the regular geographic entity and the parts of the regular geographic entity are abstracted and simplified, then feature points are extracted, a regular geographic entity area triangular facet network is built, namely the initial triangular facet network is built in a regular geographic entity area, the shape and the size of a triangular facet depends on the densities and positions of the feature points, and finally the triangular facet network is optimized to complete the Delaunay triangular facet network. The method for subtly organizing the regular geographic entity space geometry data has the advantages that a regular geographic entity space geometry structure is subtly expressed, the interior of the geographic entity is made to have the description of space topological relation, and a feasible method is provided for solving subtle analysis problems such as subtle organizing of the smart city regular geographic entity space geometry data and an interior optimal path analysis.

Description

technical field [0001] The invention relates to the organization and management of geometric data of regular geographic entities in geographic space, and provides a data organization method for the geographic information system (GIS) to finely manage the spatial geometric information of regular geographic entities in smart cities, belonging to geographic information systems (GIS ) technology field. Background technique [0002] The organization of spatial geometric data of geographic entities is essentially a technical means to digitally describe the dimension, position, size, shape, direction, and topological relationship of geographic entities by means of coordinates, mathematical functions, and other methods. Since humans began to use computers to collect, store, and process various graphic data related to geographical distribution, they began to study the organization methods of spatial geometric data. [0003] The organization of spatial geometric data is the basis of ...
