It's better computational performance of the proposed model when analyzing the relative relationships of moving objects than the absolute methods in a famous commercial GIS software based on this experimental results. Therefore, the motivation of this paper is to create a relative space-based GIS data model of moving objects and propose some basic GIS operators for analyzing moving objects, which changes the analysis of current absolute space-based GIS models and facilitates the efficient computation of real-time relative relationship dynamics, such as the surrounding dynamics and motion trends of crowds near moving objects. ./cache/cord-313777-eydkfqi2.txt ./txt/cord-313777-eydkfqi2.txt
