Geographic information data filtering method, electronic equipment, storage medium and system based on meshing

Abstract

The invention discloses a geographic information data filtering method, electronic equipment, storage medium and system based on meshing. The method includes the steps of meshing a map, dividing the map into several mesh units along the longitude and the latitude; linking the geographic information of each region in the map to POI information points in the map; obtaining longitude coordinates and latitude coordinates of all the boundary points in a region to be analyzed, dividing the mesh units belonging to the region to be analyzed into the mesh units inside the boundary of the region to be analyzed and the mesh units on the boundary of the region to be analyzed; obtaining the first geographic information contained in the POI information points in the mesh units inside the boundary of the region to be analyzed; judging whether the POI information points inside the mesh units on the boundary of the region to be analyzed are in the region to be analyzed, and if so, obtaining the second geographic information contained in the POI information points, otherwise, excluding the POI information points; integrating the first geographic information with the second geographic information, and obtaining the complete geographic information of the region to be analyzed. According to the geographic information data filtering method, the range of screening is narrowed, and the efficiency of screening is improved.

Description

technical field [0001] The invention relates to the field of geographic information, in particular to a grid-based geographic information data screening method, electronic equipment, storage media and a system. Background technique [0002] Geographical information data is data directly or indirectly related to a certain location relative to the earth, and is a file of various elements that represent natural and social phenomena of geographical location and distribution characteristics. The existing geographic information data analysis is directly oriented to the basic geographic information data. Because the basic geographic information data often has a large amount of data, the calculation amount of the analysis is large, and the screening range is restricted by conditions. It cannot be screened according to the actual needs of users, resulting in low analysis efficiency. . Contents of the invention [0003] In view of the deficiencies in the prior art, one of the purpo...
