Imported 3 .dem files from a Civil 3D file. The two surfaces(topographic maps) fit correctly into my ArcMap file but the third surface, a bathymetric contour, seems to be misaligned and the scaled too big. I already tried checking the projections and units are all the same both in Civil 3D and in ArcMap. I also tried importing the files individually into a blank map but the third surface really won’t fit.
EDIT: for now I've just georeferenced the bathymetric surface into the other surfaces and it seems to be sufficient for my project but I was hoping to get a more exact answer if possible since the georeferencing is based on how precise I'm able to place the similar points and since the contours are different, it isn't really exact.
