摘要: 针对GIS中二维地图,提出了地图窗口的改变和地物运动变化的推演设计模型,给出了开发实例,解决了二维推演的关键技术问题Abstract: This paper presents a model for designing both the two\|dimensional movements of objects in a map and the variation of map window. By using this model, most proposals can not only be drawn on a map, but be made into demos. Some key technologies and an instance for improving the speed of such a system are given
