绘制海岸线

from mpl_toolkits.basemap import Basemap
m=Basemap(projection='merc',
resolution = 'h',
#          
area_thresh = 0.01,
llcrnrlon=118, llcrnrlat=23,
urcrnrlon=125, urcrnrlat=28)
#这里定下地图边界
m.drawcoastlines()  # 绘制海岸线
m.drawmapboundary()
lat = data1['y']/200000.0                     # 获取维度之维度值
lon = data1['x']/50000.0                     # 获取经度值
x,y = m(lon.values,lat.values)
m.scatter(x,y,edgecolors='r',facecolors='r',marker='*')
plt.title('Sea')
plt.xlabel('Longitude')
plt.ylabel('Latitude')
plt.show()在这里插入代码片
