Python Basemap does not show the proper plot

Question

I need to plot some data over a map of the city of Amsterdam, but I can't get Basemap to display the proper plot. With the code below, all I get is an empty plot and I don't know how to get the map to display.

My code is below:

from mpl_toolkits.basemap import Basemap
import matplotlib.pyplot as plt
%matplotlib inline

#Create a map around Amsterdam
#http://www.latlong.net/
#Upper Right Corner 52.4268763,5.2415393
#Lower Left Corner 52.3303609,4.6992733

#fig, ax = plt.subplots()
m = Basemap(projection='merc', 
        llcrnrlat=52.3303609,urcrnrlat=52.4268763,
        llcrnrlon=4.6992733, urcrnrlon=5.2415393,
        resolution='c')

m.fillcontinents()
m.drawcoastlines()
m.drawmapboundary()
plt.show()

What am I missing in my code?

You are missing the actual plot command -- where should the actual data for your map come from? — Thomas Kühn

@Thomas I guess he means the coastlines which are not shown. Additional data must of course be drawn seperately. — ImportanceOfBeingErnest

The resolution you chose for the basemap, resolution='c' is "coarse", meaning that detailed coastlines will not be shown. You can use any of the other possible resolutions

l (low), i (intermediate), h (high), f (full)

Example:

resolution="l":

resolution="i":

resolution="h":

resolution="f":

Code to reproduce:

from mpl_toolkits.basemap import Basemap
import matplotlib.pyplot as plt

m = Basemap(projection='merc', 
        llcrnrlat=52.3303609,urcrnrlat=52.4268763,
        llcrnrlon=4.6992733, urcrnrlon=5.2415393,
        resolution="f")

m.fillcontinents(color='bisque')
m.drawcoastlines()
m.drawmapboundary(fill_color='lightcyan')

plt.show()
