Hi, I am not sure if this is even possible, but I would like to use 5 or 6 different maps taken at varying altitudes but of the same region and create one model/map.
As a user zooms in on the model/map the texture would update. For example: Say I had a map of North America, then a more detailed map of the United States, and finally another detailed map of just a state in the US. As the user zooms in they would see North America, then the United States, and finally a detailed state map. >From the little bit of experimenting I have done, I have thrown all the >geotiffs in one folder (from all 3 different maps) and built a model.

So its like 3 >different map formats all on one map and looks like some kind of Frankenstein >monster. What I would like is for all of the North America map to display, then as the user zooms in, if a more detailed view/map is available, it should update accordingly, showing the detailed portions only if the user is at the necessary scale/zoom level. I hope this makes sense, I feel I explained it horribly. Is this even possible using VPB/osgdem? Are there any other tools that may work better? Thank you!
