ESRI ArcGIS Server - Map Cache
With ESRI ArcGIS Server, you can create publish map services and create map caches. A map cache is a pre-generated hierarchy of map tiles that speeds up the serving of static map data. This driver allows osgEarth to access these map caches directly.
ArcGIS Server can expose the map caches directly by way of an IIS virtual directory. Usually this appears at a URL similar to
http://server/arcgiscache
Use this URL with this driver and you can access the map cache of any layer in that virtual directory.
Note: In the future we intend to fold this into a general ArcGIS Server driver that will also support the ArcGIS Server REST interface.
Specs
- Profile: global-mercator is the only one supported for now. Support for the ArcGIS tile spec XML file is planned.
