In this tutorial with Basemap, you are shown how to actually plot a plot, as well as choose a zoom level on your projection. As you can see, plotting lat and long coordinates is fairly simple if you envision them as X and Y on a plane. The only confusing part is that X, Y translates to Lon, Lat... which is the reverse of how they are normally reported.
From the video, here is the sample code:
from mpl_toolkits.basemap import Basemap import matplotlib.pyplot as plt def mapTut(): m = Basemap(projection='mill',llcrnrlat=20,urcrnrlat=50,\ llcrnrlon=-130,urcrnrlon=-60,resolution='c') m.drawcoastlines() m.drawcountries() m.drawstates() m.fillcontinents(color='#04BAE3',lake_color='#FFFFFF') m.drawmapboundary(fill_color='#FFFFFF') # Houston, Texas lat,lon = 29.7630556,-95.3630556 x,y = m(lon,lat) m.plot(x,y, 'ro') lon, lat = -104.237, 40.125 # Location of Boulder xpt,ypt = m(lon,lat) m.plot(xpt,ypt, 'go') plt.title("Geo Plotting") plt.show() mapTut()The above code will generate a map in Matplotlib and Basemap with coordinates plotted for Houston TX and Boulder CO.
