摘要
针对GPS轨迹数据可视化的需求,采用KML技术设计具有针对性的数据管理构件。通过对NMEA-0183数据解析和基于Bursa-Wolf方法的空间数据转换等过程,实现一种空间数据精确转换到KML的方法,成功应用于某GPS数据管理平台,为其提供高效、可靠的GPS轨迹数据可视化与交互处理功能。
In order to meet the needs of GPS Trajectory Visualization,Data management component was designed by KML technology.Through the methods of NMEA-0183 data analysis and Bursa-Wolf formula,A method of data transformation from precise spatial data to KML was achieved.And the method has been successfully applied to the GPS data management platform,the superior spatial trajectory data visualization and interactive processing functions was provided.
