摘要:

介绍一种基于GPS/PDA技术的水源定位系统的设计方案。该方案中,针对传统球面距离算法复杂度高,在手持平台实时性无法保证的问题,对算法做出改进,并且在Windows Mobile操作系统下,基于.NET平台使用C#开发出一套水源定位系统。系统包括水源位置信息的采集,水源位置数据库的组建,以及对水源数据库的操作。该系统,在保证精度的同时,降低了算法的复杂度,提高了手持定位系统的实时性和可用性。

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.
