High-efficiency storage method for mass geographic information tile data

The invention relates to a high-efficiency storage method for mass geographic information tile data, which comprises the following steps of: S1, carrying out slicing processing on a satellite image data source file and a digital altitude data source file, forming a tile database after slicing, and finally, packaging the tile database into data files; and S2, when a GIS (Geographic Information System) needs to acquire data, finding a corresponding data file in the data files generated in the step S1 by a data parsing plug-in, and finally, acquiring tile data to load into a scene. According to the invention, a great amount of file IOs are shortened into an IO of one file, so that reading efficiency of tiles is improved, and efficiency of the GIS is improved. 种海量地理信息瓦片数据的高效存储方法，包括以下步骤：步骤1，对卫星影像数据源文件和数字高程数据源文件进行切片处理，切片后形成瓦片数据库，并最终对瓦片数据库打包为数据文件；步骤2，当地理信息系统GIS需要获取数据时，通过数据解析插件在步骤1中生成的数据文件里找到对应的数据文件，最终获取到瓦片数据加载到场景中；本发明将很多的文件IO缩短为个文件的IO，提升了瓦片的读取效率，提高了GIS的效率。
