本程序是海洋地质制图常用地图投影系列小程序,程序能用于WGS84、北京54、西安80基准面上单点及批量数据的投影正反转换,
本套系列程序目前包括“3°、6°带高斯-克吕格投影正反转换程序”、“墨卡托投影正反转换程序”及“兰勃托投影正反转换程序”。
编制这套程序原因有三:之一,本人工作中常需要投影计算,现有软件使用不太方便;之二,常发现用十进制度坐标数据作正式成果图的现象,
可能是手头没有合适的投影软件所至;之三,常发现WGS84定位数据被当作北京54(克拉索夫斯基椭球体)坐标数据投影

墨卡托投影,与地轴方向一致的圆柱切于或割于地球,按等角条件将经纬网投影到圆柱面上,将圆柱面展为平面后,得平面经纬线网。投影后经线是一组竖直的等距离平行直线,纬线是垂直于经线的一组平行直线。各相邻纬线间隔由赤道向两极增大。一点上任何方向的长度比均相等,即没有角度变形,而面积变形显著,随远离标准纬线而增大。-Mercator projection is consistent with the direction of the Earth s axis cylinder cut in or cut i
