Zusammenfassung:The invention discloses a map tile data processing method and device, and the method comprises the steps: carrying out the classification and compression of tile data of a three-dimensional map according to different scales, building data files of a plurality of scales, and building a tile data index; and based on the data files of multiple scales, constructing a spatial continuous scale expression model so as to realize continuous expression of the data files of multiple scales when a dynamic data request of a user is received. According to the invention, massive tile data is classified and compressed and an index is established; the organization mode of the data can be changed; efficient file storage is built, thus improving transfer efficiency of data, and the spatial continuous scale expression model is constructed based on the discrete scale data file, so that the scale continuity of the tile data can be realized, the continuous scheduling of the user for the tile data can be satisfied, and therefore, di
