1 results about "Equidistant grid" patented technology

This invention discloses a spatial grid generation method based on geometric constraints, specifically including: acquiring spatial range data of the target area and performing latitude and longitude analysis to generate a reference grid set; constructing a Cartesian coordinate system and converting latitude and longitude into a spatial coordinate set; performing recursive quadrilateral partitioning based on preset side lengths to generate a multi-level equidistant grid cell set; establishing a hierarchical mapping using GeoSOT level 15 grids to form a fused grid structure; establishing an encoding structure to generate a grid encoding sequence; establishing geographic entity mapping relationships to generate a grid set; and performing distance calculation, area calculation, and intersection / merge operations based on the grid set to generate topological relationship results. This invention achieves equidistant partitioning and fused encoding calculation of spatial grids, significantly reducing the complexity of spatial distance and area calculations while improving computational accuracy and processing stability.
