Abstract
A handheld graphic user interface (GUI) personal digital assistant (PDA) computer is coupled to a GPS/dGPS receiver module which is also compact in size to provide for the collection of data associated with position information. Additional features provided by the stored program in the PDA include a nested set of menus for pre-organizing data collection, navigational functions to permit a user to navigate to a desired location with audio and visual feedback, mapping capability, overlay generation functions which further organize and display the collective data, etc. A full host of functionality provided by a geographical information system (GIS) software package are not provided due to the limited processor performance capability and memory space but only data collection data and mapping display and generation capabilities as selected for implementation of the desired functions.
