# Change the Angle Altitude of the Sun
# -------------------------------------
# Another variable you can adjust for hillshade is what angle of the sun.
# The ``angle_altitude`` parameter values range from 0 to 90. 90 represents the sun
# shining from directly above the scene. The default value for ``angle_altitude`` in
# ``es.hillshade()`` is 30 degrees.

# Adjust the azimuth value
hillshade_angle_10 = es.hillshade(elevation, altitude=10)

# Overlay a DEM on top of the Hillshade

# Create the Hillshade
# --------------------
# Once the DEM is read in, call ``es.hillshade()`` to create the hillshade.
