Tiling mechanism |
In the traditional GIS map services, map cache indicates map tiles precached on standalone computers, and the tiles are provided to the outside world by the standalone computer. This traditional tiling technology make low use of computing resources and it takes months or even years for massive data caching, which greatly affect work efficiency. What is worse, there is no obstacle recovery mechanism, the entire tiling task needs to be redone once an error occurs.
In an era that cloud computing is developed in a fast speed, SuperMap iServer proposes a new tiling technology: Distributed Tiling Technology. Distributed tiling technology supports distributed tiling and storage management of map tiles. Multiple distributed file systems, NAS and massive data storage system (such as FastDFS, MongoDB, EMC Isilon, etc) are supported to significantly enhance the I/O speed and concurrency of map tiles.
Distributed map tiling service of SuperMap iServer make use of the advantage of cloud platform to enhance tiling efficiency and stability of massive data.
