Procedures for a sample implementation, using GPS to collect utility data, are described using Pathfinder Office software to create a new project and data dictionary, transferring the data dictionary to a datalogger, using Quick Plan software to preplan data collection, using the ProXL Datalogger to collect data, downloading the data to a PC, differentially correct the data using base station data, and exporting the results to ArcView.
