Projection Mapping on 3D Landscape

Hi all, I’m pretty new to projection mapping (and texturing as well) and have done only small easy setups so far. For an exhibition I want to project a 2d aerial image of a terrain (mostly flat and a few hills) onto a 3d representation of the same aerial image. So, what we’re actually doing is reconstructing this 3d representation (a 3d table) from the topographical data of the aerial image.

Now, is it possible to simply project that image onto the 3d representation using flat mapping (e.g. in c4d) and to use those uv coordinates for the mapping or is this a way more complicated process? This is important for us, because if the mapping is not perfect, the contour lines of the 2d image will not match the 3d height differences.

Kind regards
