CHaMP). The tool is an ArcGIS Add-In and when added shows up as a toolbar:
Ecogemorphology & Topographic Analysis Lab (ET-AL) and the RSGIS Laboratory developed this ArcGIS Add-in for the transformation and projection of CHaMP field survey data (Bouwes et al. 2011) into real world coordinates given hand-held GPS coordinates from just three benchmarks. The CTT will work with any unprojected data in a file geodatabase, and gives you multiple ways to do an afine transformation based on a simple shift and rotation. Although other transformation tools exist in ArcGIS, there is not a simple sequence of geoprocessing tools, which allow you to transform vector data in a manner that preserves the high relative accuracy of a total station survey. See Wheaton et al. (2012) and the ReadMe page for more background.
