Mass spatio-temporal data visualization performance optimization method and system based on multi-dimensional index

The invention discloses a mass spatio-temporal data visualization performance optimization method and system based on multi-dimensional indexes, and the method comprises the steps: mastering the data characteristics and data formats of spatio-temporal data, carrying out the organization and management of the spatio-temporal data according to an application scene, and carrying out the optimization of the visualization performance of the spatio-temporal data. According to the method, a KD-Tree and histogram fused KD-H technology is provided, query performance is optimized for non-aggregation query and aggregation query, after spatio-temporal data is organized and managed, a multi-dimensional index and a histogram are constructed, and after proper KD-Tree and histograms are constructed for different application scenes, the query performance is optimized. A public map geographic space visualization map is used as a base map, on a high-performance WebGL rendering framework based on big data visualization, the incr
