Abstract

The invention provides a large-area geographic information overlapping area determination method and device, equipment and a medium, and relates to the field of artificial intelligence, the method comprises the following steps: constructing a spatial database, and obtaining a polygonal area of which the area exceeds a set threshold from the spatial database, the polygonal area being used for representing geographic features; recording position information of a preset number of point data in the polygonal area; clustering the position information of the point data to obtain cluster centers corresponding to a plurality of clustering clusters; dividing the polygonal area into a plurality of sub-areas according to the cluster centers, wherein each sub-area is provided with only one cluster center; according to an intersection between the sub-regions corresponding to different polygonal regions, determining an overlapping region between the corresponding polygonal regions; the method can effectively solve the problems of low efficiency and long time consumption of large-area geographic information calculation.

Description

technical field [0001] The invention relates to the field of artificial intelligence, in particular to a method, device, equipment and medium for determining overlapping regions of large-area geographic information. Background technique [0002] At present, the technology of superimposing and intersecting the Geometry geographic information of two surfaces is completed through the st_intersection function that comes with the PostgreDatabase plug-in similar to Postgis. Although this function is easy to implement and the result is feasible, when one piece of Geometry data involves a large area, the algorithm is inefficient and takes too long. Contents of the invention [0003] In view of the above existing problems in the prior art, the present invention proposes a method, device, equipment and medium for determining overlapping areas of large-area geographic information, mainly to solve the problems of long time-consuming and low efficiency in calculating large-area geograp...
