Run test with:
$ python ibcao.py
or in your code do something like:
print ("testing ibcao class") import matplotlib.pyplot as plt import matplotlib.cm as cm import cartopy.crs as ccrs i = IBCAO () f = i.template (10) # only plot every 10th data point # lets put some text along the parallels lat = np.arange (65, 90, 5) lon = np.repeat (0, len(lat)) # regular lat, lon projection g = ccrs.Geodetic () for lon, lat in zip (lon, lat): plt.text (lon, lat, str(lat), transform = g) # and some along the meridians lon = [-45, 45, 135, -135] lat = np.repeat (70, len(lon)) for lon, lat in zip (lon, lat): plt.text (lon, lat, str(lon), transform = g) # also; the north pole plt.text (0, 90, "NP", transform = g) plt.show ()
check out the test cases in tests/ for some inspiration on how to use the class.
