Detailed Description

DtOsgEarthCache.

DtOsgEarthCache manages the caching of osgEarth tiles. It supports caching using the osgEarth API or flying a camera to the interseted area to invoke the data pager to generate cache.

Parameters

skip	if true, it will skip caching image layers.

virtual void makVrv::DtOsgEarthCache::setCacheElevationLayers ( bool val )

virtual
