python通过经纬度点制图_python basemap 画出经纬度并标定的实例

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 a
