fig = plt.figure(figsize=(10,10))
ax = fig.add_subplot(111, projection=ccrs.PlateCarree())

draw_maps(get_adm_maps(level='国')) 
plt.show()

绘制省界

cnmaps还可以绘制各省(特区/直辖市)的地图

import cartopy.crs as ccrs
import matplotlib.pyplot as plt
from cnmaps import get_adm_maps, draw_maps

fig = plt.figure(figsize=(10,10))
ax = fig.add_subplot(111, projection=ccrs.PlateCarree())

draw_maps(get_adm_maps(level='省'), linewidth=0.8, color='r') 

plt.show()

绘制市界

cnmaps可以绘制市级的行政区地图。

import cartopy.crs as ccrs
import matplotlib.pyplot as plt
from cnmaps import get_adm_maps, draw_maps

fig = plt.figure(figsize=(15,15))
ax = fig.add_subplot(111, projection=ccrs.PlateCarree())

draw_maps(get_adm_maps(level='市'), linewidth=0.5, color='g') 

plt.show()

绘制区县界

cnmaps可以绘制区县级的行政区地图。

import matplotlib.pyplot as plt
from cnmaps import get_adm_maps, draw_maps

fig = plt.figure(figsize=(20,20))
ax = fig.add_subplot(111, projection=ccrs.PlateCarree())

draw_maps(get_adm_maps(level='区县'), linewidth=0.8, color='r')
