Paper Abstract

Geospatial information contains not only spatial information and attribute information, but also the information related with spatial information evolvement. As the development of the instruments and technology to acquire geospatial information, more and more geographical information contains spatial-temporal information, as a result, temporal-GIS(Temporal-Geographic Information System, TGIS for short) comes into being. Temporal-GIS could analyze and solve the spatial evolvement characteristics in geographical phenomenon, and reproduce the spatial-temporal scene of real world. This project is focusing on the dynamic visualization of geospatial data based on temporal-GIS, designing the interpreter arithmetic for geospatial polygon dynamic display, building dynamic display model based on temporal-GIS, subsequently, the model is used to analysis and solve the dynamic evolution characteristics of geographic phenomenon, reproduce the real-world temporal -spatial scenes, predict the developing trend of geo-data with the visualization methods.
