cnmaps 是一个以中国领土主张为标准开发的地图类 Python 扩展包
安装
安装 cnmaps 需要满足 Python 的解释器在 3.9 版本及以上。
使用pip安装
cnmaps 最简单也最快的安装方法是使用 pip 来安装 cnmaps： $ pip install -U cnmaps
从 2.0.0 开始，官方边界与样例数据已经拆分到独立包 cnmaps-data；安装 cnmaps 时会默认一并安装 cnmaps-data，无需再手动准备内置数据目录。
使用conda安装
你也可以使用 conda 安装： $ conda install -c conda-forge cnmaps
补充说明：conda-forge 当前只维护到 1.1.7 版本；2.x 及后续版本仅发布到 PyPI，conda 发行将停止后续维护。
快速开始
绘制国界
用最简单直接的方式，来绘制你的第一张中国地图。
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(country='中国', 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 cartopy.crs as ccrs
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')
plt.show()
