Hey,
i recently began fooling around with a 3-D mapping program 3DEM and it allows you to overlay a georeferenced tiff image over the elevation data. Although the program allows you to import more than one DEM file, it will only allow you to import a single TIFF. Does anyone know of a utility that can combine the tiffs and retain the georeferenced data? Or does anyone know of a program similar to 3DEM that can import multiple tiffs. This is just for fun so I am trying to stick with the freebie programs. Thank you in advnce.
Joe
