Performance optimization of 3D services |
Generally speaking, map caching technology is an effective method for quickly accessing the map services. According to certain mathematical schemes, the maps are partitioned into tiles with certain specifications and are deployed into server. When users access map services with the client browser, the server can directly return the right cached images within current map coordinate domain, and thus reduce the server's burden and improve the map browsing speed efficiently.
Map caching technology can be applied to the large mount of data of which the update frequency is low, to improve the map browsing speed notably, thus improve the users' experiences. For 3D data, SuperMap iServer provides a complete caching system, such as precaching, dynamic caching, etc.
