Abstract:

This paper introduces a design of water source locating system based on GPS/PDA. The design includes an improvement of the spherical distance algorithm, which is too complicated to be used on handheld equipments in traditional. A water source locating system is developed with C# based on .Net platform in Windows Mobile. This paper describes the way to collect the location of water source, create location database, and operate the database. This system reduces the complexity of the algorithm while assuring the accuracy, so that it enhances the useableness and realtime performance.

Key words: PDA, GPS, water source locating, blue tooth
