python basemap 画出经纬度并标定的实例
如下所示：
两个函数：Basemap.drawparallels##纬度 Basemap.drawmeridians##经度 frommpl_toolkits.basemapimportBasemap importmatplotlib.pyplotasplt importnumpyasnp #setupLambertConformalbasemap. m=Basemap(width=12000000,height=9000000,projection='lcc', resolution='c',lat_1=45.,lat_2=55,lat_0=50,lon_0=-107.) #drawcoastlines. m.drawcoastlines() #drawaboundaryaroundthemap,fillthebackground. #thisbackgroundwillendupbeingtheoceancolor,since #thecontinentswillbedrawnontop. m.drawmapboundary(fill_color='aqua') #fillcontinents,setlakecolorsameasoceancolor. m.fillcontinents(color='coral',lake_color='aqua') #drawparallelsandmeridians. #labelparallelsonrightandtop #meridiansonbottomandleft parallels=np.arange(0.,81,10.) #labels=[left,right,top,bottom] m.drawparallels(parallels,labels=[False,True,True,False]) meridians=np.arange(10.,351.,20.) m.drawmeridians(meridians,labels=[True,False,False,True]) plt.show()
