RESEARCH ON KEY TECHNIQUES OF GIS/GPS INTEGRATION BASED ON PDA
研究了在PDA上集成GPS和GIS的关键技术，包括GPS信号的移动计算、实时显示、PDA环境选择及移动GIS系统开发问题，对从事移动地理信息应用的研究者有参考价值。
Embedded GIS is a newly developing application field. It is a result that GIS combines with newly developing embedded hardware.And it is a branch ,supplement and development of the original GIS field. Embedded GIS based on PDA combined with GPS is promising in realizing the real display of the maps under the mobile computation situation.This research focuses mainly on some key technology of GPS and GIS integration running on PDA,for instance: how GPS signal realize mobile computation;how GPS signal realize real display on pocekt PC;the environmental choice on PDA of GPS/GIS integration and the questions on developing mobile GIS system。
