Hi Xuex Chen, I'm afraid I don't understand the issue that you have. VPB can deal with datasets in different projections by coordinate systems them all into the same coordinate system that the final database will end up in, as long as your data has all the correct coordinate system info embedded (such as GeoTiff) in it should simply be a case of add all your files to the osgdem/vpbmaster command line.
