Three-dimensional tile storage and distribution method and device

The invention discloses a three-dimensional tile storage and distribution method, and relates to the field of three-dimensional GIS (geographic information system), in particular to a three-dimensional tile storage and distribution method and device, which can realize storage management of massive three-dimensional tiles by using an open-source distributed file system so as to solve the problems of distributed storage, high availability and efficient retrieval of the massive tiles. On the basis of combination with a lua script language, a file management component in a distributed file system is called, tile directory organization management and tile path retrieval are achieved, and the tile storage management and read-write process is simplified; and meanwhile, efficient retrieval and quick response of the tiles are realized in combination with an application server cache mechanism. 本发明公开了一种三维瓦片存储与分发方法，涉及三维GIS领域，特别涉及一种三维瓦片存储与分发方法和装置，其利用开源的分布式文件系统可实现海量三维瓦片存储管理，以解决海量瓦片分布式存储、高可用性及高效检索；基于结合lua脚本语言，调用分布式文件系统中的文件管
