其中,x、y、z为ECEF坐标系下的坐标,lat为纬度,lon为经度,h为点的高度,N为曲率半径,e为地球的偏心率。 Python代码示例 下面是使用Python实现LLA到ECEF坐标转换的代码示例: importmathdeflla_to_ecef(lat,lon,h):a=6378137.0# 地球长半轴长度f=1/298.257223563# 地球扁率b=(1-f)*a# 地球短半轴长度e=math...
python 经纬度(LLA)转换成地心地固坐标系(ECEF)的坐标 python经纬度画图,前言因为根据地址库的经纬度坐标很难肉眼看出规律,所以想画个图看看。网上看了很多文章,大多都是基于标准地图的,但我只是想画个相对的坐标图就好。所以干脆就用matplotlib自己写一个吧。代码impor
