Hi,
I have two groups of terrain data with geotiff format. One has common
vertical orthographic projected elevation data and image, while the other is a
part of the first group, and with a higher resolution, furthermore, its
elevation data and image are gradient orthographic projected data that
represents a protuberant escarpment(assuming knowing the image's shooting
angle). I can build each group of data separately by VirtualPlanetBuilder(abbr.
VPB) without taking account of the gradient orthographic projection, and next i
can't embeded the smaller part into the larger terrain perfectly. I think i
should build whole data in a lump, because VPB could deal with different
resolution well, but i don't known how to apply the second part's shooting
angle to building process. Anyone advance ?

Thank you very much.
