急求,请问已知中国边界上点的坐标怎么画出类似于中国在地球仪上的曲面图.?

bily6662

我现在已经知道了中国边界上若干个点的坐标(X,Y,Z,) 请问怎么能用MATLAB画出中国地图的曲面形式,类似于地球仪上的形式.求高人解答谢谢.

高手朋友,能说的明白点么?小弟感激不尽

能否把数据传上来让大家试试？

你这个挺专业，我想主要的问题不在于matlab，而在于算法。相关的matlab命令，可以参考小西版主在2楼给出的提示。

点的坐标如下,依次是X  Y Z 单位是M,点的顺序是围绕中国的一圈的边界点.

这个是什么坐标系？稍微说明一下，不然不知道你的数据怎么用的。

bily6662

这个坐标系就是笛卡儿坐标系,X Y 值是地球上一点在赤道平面的投影坐标,Z值是地球表面点到迟到平面的垂直距离
