摘要
Abstract
In the process of trajectory data recording,the geodetic height was converted to normal height with the help of the EGM2008 geoid model.In the process of trajectory data thinning,an improved spatiotemporal clustering algorithm was proposed to thin the trajectory data.In the process of trajectory data display,the trajectory is displayed and played back by using flow arrows and motion icons,so as to achieve accurate recording and rapid display of trajectory data.关键词
