GPS Coordinate Transformation Application Research in 110 Command System
Xin Bai · Geomatics & Spatial Information Technology · 2007
In 110 Command System,it is necessary to display the danymic data from GPS receiver on digital map to monitor the police vehicle.GPS data adopts WGS-84 Coordinate,while the digital map adopts Beijing 54 Coordinate.So it is a key to solve that translate the WGS-84 Coordinate to Beijing 54 Coordinate.This paper discusses the transformation problems between the WGS-84 Coordinate and Beijing 54 Coordinate.The transformation algorithm is given in detail and is applied in Fuzhou police 110 command system successfully.
