Georeferencing
Your raster, vector, CAD, and TIN geodata need map control in order to establish the geospatial relationships between the various objects in your project materials. Derive map control from existing objects by adding tiepoints in side-by-side and overlay display modes. Use an X-Y digitizer to enter coordinates from paper maps, or place control points with coordinates from GPS devices.
