绘制海岸线国界州界及填充海陆

5 J; q3 \6 G5 z1 n" @; Y

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

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

此处海洋颜色的天蓝色

#87CEEB

2 d) l' o3 P/ X6 `6 x; U

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
