绘制海岸线国界州界及填充海陆

# H* W0 ?* \. ?0 N

1. 海岸线 Basemap.drawcoaslines()

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

( y+ z$ k% ~5 _; F! {* G

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

# H$ G9 X2 [: w! B1 r7 d% {

此处海洋颜色的天蓝色

2 d& S3 M1 U$ E1 J0 H

#87CEEB

& S" K) Q( g% e& G

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
