AI Technical Summary
Technical Problem
In existing technologies, storing map tiles requires a large amount of storage resources, resulting in wasted storage space and low data processing efficiency.
Method used
The map tile data is divided into multiple hierarchical sets, and first and second map tile files are generated for each hierarchical set. The organization structure of file header, index area and data area is adopted to reduce the number of map tile files and storage space.
Benefits of technology
It effectively saves storage space, improves the efficiency of data processing and deployment of map tile files, reduces the number of files, and increases the speed of data migration.

Abstract
本申请提出一种地图瓦片存储方法、查询方法、装置、设备及存储介质，涉及数据存储技术领域，用于减小存储地图瓦片数据所占用的存储空间。该方法包括：地图瓦片存储装置获取地图瓦片数据；地图瓦片数据包括多个层级的地图瓦片；并将多个层级进行划分，得到多个层级集合。进一步的，地图瓦片存储装置从地图瓦片数据中确定每个层级集合的第一地图瓦片，得到多个第一地图瓦片；并从地图瓦片数据中确定每个第一地图瓦片对应的第二地图瓦片。地图瓦片存储装置根据每个第一地图瓦片，以及每个第一地图瓦片对应的第二地图瓦片，生成每个第一地图瓦片对应的地图瓦片文件，并存储每个第一地图瓦片对应的地图瓦片文件。
