摘要
根据全球地形高程差资料 ,运用可视化技术对常用投影天气图底图上的地形信息进行重构 ,得到了有地形信息的地图投影天气底图 ;针对三维地形信息重构重 ,提出了一个三维地形投影算子 ,设计并实现了算子计算的递归算法 ,得到真实感三维地形可视化结果。
In this paper the global topographic data is used to rebuild the geographical information on the normal synoptic base map with the visualizing technology in scientific computing, the projected maps with geographical information are obtained; a telluric projection operator is proposed and a recursion algorithm is designed to implement the operator computation, and in this way the three dimensional telluric projected synoptic base map are retrieved.
