今天小编就为大家分享一篇python basemap 画出经纬度并标定的实例，具有很好的参考价值，希望对大家有所帮助。一起跟随小编过来看看吧

如下所示：

				?

									两个函数：Basemap.drawparallels ##纬度

									     Basemap.drawmeridians ##经度

									from mpl_toolkits.basemap import Basemap

									import matplotlib.pyplot as plt

									import 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 left

									parallels = 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()
