Cache Configuration for Map Service

SuperMap iServer has taken a series of measures to improve the efficiency of online map access, among which caching technology is the most effective way. For map services, you can: configure to enable HTTP caching, configure to enable request caching that covers all functional services, and divide online maps into three types of tiles: map tiles, vector tiles, and attribute tiles.

For the caching strategy of SuperMap GIS series products, please refer to: Caching Strategy.

Improving the efficiency of online map plotting through map caching technology is a professional and continuous work that requires the comprehensive use of multiple products. The basic process is as follows:

For specific operation, please refer to the production and use process of map tiles . Among them, for the cutting work with the highest time cost, SuperMap iServer also provides a distributed cutting service to help you further improve the efficiency of your cutting work.

Tiles produced by the distributed graph cutting service, whether they are map tiles, vector tiles, or attribute tiles, except for UGCV5 tiles, can be automatically used by the map service without additional configuration. You can manually configure service providers to use UGCV5 tiles . If you have modified the default storage path for slicing or made other customizations, you need to configure map services to use the existing tiles .

In addition, you can publish map tiles directly as map services, and you can also distribute the tile data files and slice sets obtained by slicing for offline sharing.

Finally, in the process of using map tiles, you may encounter a situation where map services data changes and you need to update map tiles. In this case, you can refer to: how to update map tiles .
