摘要
针对地图信息系统输出图形坐标系分布不均问题,设计基于MapInfo的分布式预测图形仿真系统,实现可视化地图信息输出。设置控制点坐标,根据虚拟环境的地图数据构建三维模型,通过AutoCAD程序动态地生成电子地图。采用图层控制技术自动跟踪地图的空间坐标,在MapInfo中显示栅格地图,将各种地图信息数据通过程序加载模块实现数据在线调度,自动生成地图信息,实现分布式预测图形仿真系统的优化设计。仿真结果表明,采用该系统进行地理图形仿真系统设计,输出图形的坐标系分布准确,显示地图信息的准确度较高,图形的自动跟踪性能较好。
In allusion to the uneven distribution of graphic coordinates output by the map information system, a distributed predictive graphics simulation system based on Mapinfo is designed to realize output of visualized map information. The control point coordinates are set. The three-dimensional model is constructed according to map data in virtual environment. The electronic map is dynamically generated by using the AutoCAD program. The map layer control technology is adopted for automatic track of map space coordinates to display the grid map in MapInfo. The program loading module is used for online scheduling of various map information data to automatically generate map information and realize optimization design of the distributed predicative graphics simulation system. The simulation results show that the system for geographic map simulation system design has accu- rate coordinate distribution of output graphics, high accuracy in displaying map information, and good performance of graphics automatic tracking.
