The Spatio-Temporal Data Modeling and Application Based on Graph Database

Traditional spatio-temporal data model (STDM) is based on relational database, it is hard to convert problem domain model to relational model, which result in complicated query and low expansibility. In this regard, we propose the spatio-temporal data model based on graph database. The data model integrates TGIS's three key elements: space, time and attributes, and expressed spatio-temporal characteristics of TGIS explicitly. Finally, this paper gives a particular description of logistics distribution route optimization. Experimental results show that the model is proved to be appropriate for expressing the spatio-temporal process of world.
