The dataset sf.afe_csa is a sf object containing 5850
features respresenting the hectometer polygons along the axis of the river
Elbe that are approximately 100 m apart from each other. This allows the
data querying in a resolution of 100 m for the whole river. For every
hectometer polygon the data.frame contains 13 attributes.
