绘制海岸线国界州界及填充海陆

1. 海岸线 Basemap.drawcoaslines()

# W" B0 B+ [/ o; }9 ~9 x' Y

2. 国界线 Basemap.drawcountries()

特别要注意国界线有无争议，此处主要说明basemap画国界线的用法，实际国界线以我们国家（中国）制作的地图为准！

3. 州界线 Basemap.drawstates()，主要针对美洲

import numpy as np import matplotlib.pyplot as plt from mpl_toolkits.basemap import Basemap 5 {( |+ v/ t3 Q6 [ map = Basemap() map.drawcoastlines(color=r, linewidth=.5) map.drawcountries(color=g, linewidth=.25) map.drawstates(color=b, linewidth=.2) , G" ]1 s/ D- K8 k1 X) e map.drawparallels(circles=np.linspace(-90, 90, 7), labels=[1, 0, 0, 0], color=gray) map.drawmeridians(meridians=np.linspace(-180, 180, 13), labels=[0, 0, 0, 1], color=gray) " \: A3 j. q; i) L4 \: P5 v( q" Y plt.show()

4. 用不同颜色填充海洋和陆地

: j5 h) b; f; X) M+ D

4.1 海洋 Basemap.drawmapboundary(fill_color=#87CEEB)

* B) T& Y" ~& `/ E

此处海洋颜色的天蓝色

#87CEEB

4.2 陆地及湖泊 Basemap.fillcontinents(color=#808000, lake_color=#87CEEB)

陆地为橄榄色

* q& W0 k! m" G% |$ c) |

#808000

湖泊为天蓝色

5 c- ^# G' \, ?) j

#87CEEB
