A simple, interactive GIS tool for transforming assumed total station surveys to real world coordinates - the CHaMP transformation tool

► A simple GIS tool was developed for transforming total station data into real world coordinates. ► The transformation preserves the relative accuracy of the total station survey. ► Real world coordinates for the transformation can be acquired from cost-effective handheld GPS. ► The interactive tool allows visualization of survey data in a webGIS (e.g., Google Earth). ► The tool has been tested by 12 crews at 364 sites in a new stream monitoring program.
