You will have the right DEM and the right map(s) if the two fit together. Open them both in TransDEM. The DEM should lie on top of the georeferenced map(s) and the map features should make sense with the DEM, in particular watercourses being at the bottom of valleys.

If the two do not match, how did you acquire both DEM and raster maps?
