绘制海岸线国界州界及填充海陆

$ z+ ~# t8 R3 `8 G

1. 海岸线 Basemap.drawcoaslines()

$ t3 e( j+ m+ M9 e! C

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

import numpy as np import matplotlib.pyplot as plt 4 c$ b( [$ Y, G5 O from mpl_toolkits.basemap import Basemap : v. ^5 X* R; @) j7 ?; Q# v+ r 7 `" u' d) `/ X map = Basemap() 0 j$ p0 d/ e!

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

1 |$ T- ^& W# ^8 A s% B4 ^ V

#87CEEB

' v) z0 l' B/ V( m0 n; I6 y

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
