绘制海岸线国界州界及填充海陆

+ X/ F/ y3 @+ a6 ~* b6 y2 {

1. 海岸线 Basemap.drawcoaslines()

4 d. W: E3 F+ m

2. 国界线 Basemap.drawcountries()

( h* ^& l( j# m. \

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)

# v% S' G+ I, B0 j

此处海洋颜色的天蓝色

/ h+ s$ d) C, D1 I7 T2 C( S

#87CEEB

7 W$ d- ?& u5 V& H7 ?+ \

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

& N/ ` x& b9 ]

陆地为橄榄色

#808000

! B3 n, y) Q! G a V/ B+ O) i8 s

湖泊为天蓝色

$ `8 B+ U4 J+ o
