摘要
为了在同一地理信息系统内或者不同的地理信息系统之间实现数据交换、配准和共享以及对其进行空间叠加、缓冲区分析、最佳(短)路径分析等空间分析,必须保证其在统一的坐标系下具有相同的地图投影,因此地图投影变换显得尤为重要。采用VisualBasic6.0作为软件开发平台,利用MapObjects控件编程实现了各种常见地图投影之间的任意变换。
The same map projection under unified coordinate system should be guaranteed to exchange, match and share the data in the same GIS and among different GIS and to carry out spatial analyses such as spatial overlay, buffer and shortest path analysis. Therefore, map projection transformation is much more important. A program for projection transformation between any two commonly used map projections is implemented under the software platform of Visual Basic 6.0 using (MapObjects) components.
