Zusammenfassung:The invention relates to a low-coupling spatial data processing method, which comprises the following steps of: generating a plurality of grid tile files with a preset scale according to grid data subjected to map caching; separately indexing each generated grid tile file according to a hierarchical framing mode, mapping each grid tile file to a corresponding spatial data table one by one to obtain a metadata table corresponding to a spatial data table; then storing all the generated grid tile files, and creating a grid spatial database according to the spatial data table and the metadata table corresponding to the spatial data table; executing grid tile file retrieval, and creating a user-defined vector space database for vector data in spatial data; and finally, compressing data in the grid spatial database and the user-defined vector spatial database to obtain analysable compressed data packets. 本发明涉及一种低耦合的空间数据处理方法,根据地图缓存处理后的栅格数据生成多个预设比例尺的栅格瓦片文件,且按照分层分幅方式分别对生成的各栅格瓦片文件做索引处理,并将每一个栅格瓦片文件逐一映射到对应的空间数据表中以及得到对应该空
