Project description

cnmaps

Build Status PyPI version Downloads Documentation Status contributions welcome

cnmaps是一个可以让中国地图画起来更丝滑的地图类python扩展包

安装

cnmaps依赖于cartopy>=0.19.0,因此在安装cnmaps之前请确保cartopy已安装,cartopy的安装方法

在完成cartopy的安装以后,你可以使用pip来安装cnmaps:$ pip install -U cnmaps

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(level='国')) 
plt.show()

country-level

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()

province-level

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()

city-level

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()

district-level

Logo

本项目的Logo地图是如何绘制的?请执行下面的代码。

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

fig = plt.figure(figsize=(5,5))
proj = ccrs.Orthographic(central_longitude=100.0, central_latitude=30)
ax = fig.add_subplot(111, projection=proj)

ax.stock_img()
china, sourth_sea = get_adm_maps(level='国', only_polygon=True)

ax.set_global()
ax.add_geometries(china, crs=ccrs.PlateCarree(), edgecolor='r', facecolor='r')
ax.add_geometries(sourth_sea, crs=ccrs.PlateCarree(), edgecolor='r')
ax.outline_patch.set_edgecolor('white')

plt.savefig('../static/images/logo-base.png', bbox_inches='tight')
