[osg-users] Purpose of DataSetLayer in GDAL plugin

[Jason Beverage]

Hi Robert,

I was looking through the GDAL plugin and saw the DatasetLayer class and was
wondering what it is intended for. I'm looking through the code and can't
get my head around it.

I was trying to think of a way to have VPB generate a paged database that
simply references the orginal imagey as a source file and generates the
scene graph on the fly (like ossimPlanet or ArcGlobe) and thought that
DatasetLayer might be of use in performing that type of task.

Thanks!

Jason
