Electronic map point location aggregation method based on multi-layer grid partitioning

The invention discloses an electronic map point location aggregation method based on multilayer grid partitioning, and belongs to the technical field of electronic map resource aggregation. The electronic map point location aggregation method based on multilayer grid partitioning comprises: calculating a plurality of grid fragments into a large block according to a rule; and calculating each largeblock into a plurality of irregular small blocks according to a rule, obtaining complete point location data in the large blocks in the visual area according to longitude and latitude and zoom levels, and aggregating the point location data in each small block to obtain a final aggregation point. The electronic map point location aggregation method based on multilayer grid partitioning can solvethe problems of linear display during aggregation of massive data points and unfixed aggregation points during dragging of a visual area, and has good popularization and application values. 本发明公开了一种基于多层网格分块的电子地图点位聚合方法，属于电子地图资源
