I have been tasked to use huge photographic images as textures over a ground map.

I have read some people working with MegaTextures or Virtual Textures in WebGL to address this issue.

I am looking to have 3d models run over an flat earth like surface. The surface will be a mega texture while the 3D models will be more like standard colorized renders 3D models/renders.
So... In short I was wondering if there is a part of the book that could help with this.

Thanks,
Bob
