摘要
随着GIS的日益发展和广泛普及,地理坐标和平面坐标之间相互转换需求不断增加。因为GIS,尤其是大型GIS中的空间数据往往来源于多种信息源,而各种信息源地图所采用的投影往往并不一致,各种坐标之间的变换就成为所有GIS软件不可避免的问题。此软件基于Visual C++开发平台,实现了在圆锥投影中(等角、等距离和等面积)地理坐标和平面坐标之间的相互转换。
With the development and popularity of GIS, the conversion between geographical and plane coordinates increases ceaselessly in need. Because the spatial data of GIS, especially large GIS, often comes from all kinds of information sources, and their projections are different. So all GIS softwares must be confronted with the inevitable problem of conversion among all kinds of coordinates. The software converts between geographical and plane coordinates in the Conic Projection （Conformal, Equidistant, Equal Area） based on Visual C＋ ＋.
