绘制海岸线国界州界及填充海陆

0 R3 L! Q+ h& @6 m" |

1. 海岸线 Basemap.drawcoaslines()

6 z2 E8 k# Z6 e6 g! U* a

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

4. 用不同颜色填充海洋和陆地

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

此处海洋颜色的天蓝色

2 _. K8 T# j' q* B3 A

#87CEEB

: |( h- n/ O7 {$ H: }

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

陆地为橄榄色

+ F1 N6 _! d1 k; h [" H

#808000

8 \8 {- N* Z N4 Y0 u

湖泊为天蓝色

#87CEEB
