Positioning System for Mobile Terminal Based on CG and GIS

摘要：

A new positioning system based on relative positioning principle for mobile terminals was introduced. It was designed and developed based CG and GIS techniques. Adapting to the characteristics of small hard disk and memory volume, slower speed of CPU and small size screen of the mobile terminals, the display of the point, line, polygon objects, an the annotation, road name, and the implement of inquiry and buffer analysis modules were well-designed. The system is suitable to PDA, mobile phones, and embedded devices. It can perform displaying, roaming and zooming in or out of the map, inquiring of spatial data and attribute data, controlling of layers, and buffer analysis.
