绘制海岸线国界州界及填充海陆

1. 海岸线 Basemap.drawcoaslines()

. T6 @3 {: }3 A8 h0 }' s

2. 国界线 Basemap.drawcountries()

+ t- f6 w. [9 P0 T$ {+ H

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)

" d7 U/ R9 h, D( X, I

此处海洋颜色的天蓝色

1 j8 w8 \3 [9 g, d

#87CEEB

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

9 G7 S( g+ c3 s! i5 b

陆地为橄榄色

7 {! p9 R& d( J. K: t

#808000

湖泊为天蓝色

#87CEEB
