本文讨论了在仿真系统中地理信息系统的设计与实现，并对采用曲面拟合进行地理信息的存储与显示、运用神经网络模型进行三维地形图和二维的实景地貌图的坐标映射以及促进软件的可重用性等方面进行了探索。
This article discusses the design and implementation of geographic information system in simulation system, and uses the surface fitting to store and display the geographic information. The neural network model is used to coordinate the three-dimensional topographic map and the two-dimensional real landscape map and to promote the software Reusability and other aspects of the exploration.
