Cross sections
The data of the topography are available in the form of cross section measurements, where
each measured point is given by its x, y and z coordinates.
This is an extract from the raw data:

These data have to be separated in groups belonging to one cross section and then
transformed in a way to have a z(y) relation, where the smallest y is the extreme point on the
left river side.
