绘制海岸线国界州界及填充海陆

1. 海岸线 Basemap.drawcoaslines()

0 l# P. ^8 G- j

2. 国界线 Basemap.drawcountries()

4 x3 n! B5 g+ L7 G7 m, A

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)

, m9 ^% }- ?' U; w( w5 w) V, b

此处海洋颜色的天蓝色

#87CEEB

+ W9 P& I. M4 A; ^% _

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

) a' j; Y" [; @, ]

陆地为橄榄色

#808000

湖泊为天蓝色

#87CEEB
