A method and system for population heat grid generation supporting interactive editing

Abstract

This application provides a method and system for generating population heatmaps that supports interactive editing. The method includes: performing multi-level grid subdivision on a target area to generate a set of grid cells; mapping multi-source heterogeneous population data to the set of grid cells, generating initial population heatmap values ​​for each grid cell; receiving user editing operations on the initial population heatmap values ​​of any grid cell through an interactive editing interface; responding to the editing operations based on the topological relationships between grid cells and performing consistency maintenance operations to synchronously update the initial population heatmap values ​​of related grid cells; and generating a population heatmap in real time based on the updated set of grid cells, supporting export as geographic data in a preset format. This application achieves differentiated and refined subdivision through the multi-level coding characteristics of GeoSOT; automatically triggering upward aggregation updates and downward constraint reallocation when the user edits local grid values, ensuring logical self-consistency of grid data at any level.
