Make use of a Cached Basemap

A map cache reduces the number of dynamic display layers (less processing load), and as a result your users will spend less time waiting for maps to display in the Dekho Map Client. 



Use cached map services for serving GIS data with ArcGIS Server whenever possible.




A distinction is made between what layers constitute going into the basemap (published as a cached map service), and operational layers which the Dekho User will work with (published as dynamic map services).

If data changes often, use of a cached service can still be employed.  The caching tools at 10.1 have been designed for script cache updates and can target specific parts of the cache for updates. These scripts can be scheduled to run so the cache remains in sync with the live data layers.

Queries against layers can still be executed in a cached service, but layers cannot be turned on or off within a cached service.

It is best practice to make use of a cached basemap for each Dekho Map.  Before building your own basemap review the MDS Foundation Map  and basemaps from ArcGIS Online for a suitable basemap(s) to use with your operational layers.
