绘制海岸线国界州界及填充海陆

1. 海岸线 Basemap.drawcoaslines()

0 p K# a" Z; b! K/ 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

4. 用不同颜色填充海洋和陆地

- V4 w/ x2 J1 T

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

( Y) _5 v( A4 k* `8 ~- L

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

#808000

湖泊为天蓝色

#87CEEB
