5Chapter Integrating GPS Data with GIS Data
Another Datum Lesson: I teach at the University of Kentucky’s Department of Geography, in Lexington. Several years ago I borrowed a GPS receiver from Trimble Navigation to use in a class. It had occurred to me that our departmental faculty directory listed names, office and home addresses, phone numbers, and so on, but not, as seemed appropriate for geographers, their geographic coordinates. So I sent my students out to park in my colleagues’ driveways and collect GPS data, which we converted to an ESRI data set based on World Geodetic System of 1984 (WGS84) Universal Transverse Mercator (UTM) coordinates.
