1. A method for generating a surface topology map of a surface, comprising: collecting a plurality of survey sample points of the surface from a surveying instrument; collecting a plurality of profile sample points of the surface from a profiler device; correlating on a data processing device the profile sample points with the survey sample points in the Z direction; merging on the data processing device the plurality of survey sample points and the correlated profile sample points; and generating, with the data processing device, the surface topology map of the surface from the merged plurality of survey sample points and the correlated profile sample points.
