Exercise 1

The migration data of which birds (bird_names) are in the tracking dataset?



In [7]:

    
# TODO









    Out[7]:





array(['Eric', 'Nico', 'Sanne'], dtype=object)

Exercise 2

Draw a basic plot of the track(x-axis: longitude, y-axis: latitude) of each bird:

The title of the plot should be Bird Migration.
The axes should be named.
A legend should show to which bird the single tracks belong.



In [21]:

    
# TODO

Exercise 3

Draw the flight route on Cartopy

conda install -c scitools cartopy=0.15.0
# or (if former does not work)
conda install -c conda-forge cartopy=0.15.1



In [10]:

    
import cartopy.crs as ccrs

Exercise 3.1

Draw the flight route with PlateCarree-Projection

See TODOs, where to change/insert your code.



In [24]:

    
plt.figure(figsize=(10,10))
ax = plt.axes(projection=ccrs.PlateCarree())
ax.coastlines()

# TODO 1: comment in/out and see, what happens
# ax.set_extent((-25,20,52,10))

# TODO 2: draw the single tracks with title and legend as in Exercise 2

Exercise 3.2

Draw the flight route with Mercator-Projection

Use Features to show

LAND
OCEAN
COASTLINE
BORDERS
LAKES
RIVERS

See TODOs, where to change/insert your code.
