如下所示：

两个函数：Basemap.drawparallels ##纬度     Basemap.drawmeridians ##经度from mpl_toolkits.basemap import Basemapimport matplotlib.pyplot as pltimport numpy as np# setup Lambert Conformal basemap.m = Basemap(width=12000000,height=9000000,projection='lcc',      resolution='c',lat_1=45.,lat_2=55,lat_0=50,lon_0=-107.)# draw coastlines.m.drawcoastlines()# draw a boundary around the map, fill the background.# this background will end up being the ocean color, since# the continents will be drawn on top.m.drawmapboundary(fill_color='aqua')# fill continents, set lake color same as ocean color.m.fillcontinents(color='coral',lake_color='aqua')# draw parallels and meridians.# label parallels on right and top# meridians on bottom and leftparallels = np.arange(0.,81,10.)# labels = [left,right,top,bottom]m.drawparallels(parallels,labels=[False,True,True,False])meridians = np.arange(10.,351.,20.)m.drawmeridians(meridians,labels=[True,False,False,True])plt.show() 

以上这篇python basemap 画出经纬度并标定的实例就是小编分享给大家的全部内容了，希望能给大家一个参考，也希望大家多多支持。
