Improve river estimation stage - address downriver wall artefacts
The river estimation approach appears to introduce an 'wall artefact' down river amplified from any high elevation values detected along the measured cross section data.
As an example:
"See below the strange artifact of a ridgeline in the river that seems like an exaggerated version of a small positive feature in the surveyed XS (0.5 m), increased to 3 m in the interpolated data and extending to the next XS upstream and downstream."
Starting point: Could it be due to the taking the nearest point along the measured sections instead of interpolating the value nearest to the sample locations.. https://github.com/rosepearson/GeoFabrics/blob/main/src/geofabrics/bathymetry_estimation.py#L772
Also support providing just a thalweg and wetted area instead of river banks. If providing the wetter area the thalweg is not optional it is required.
Update documentation to make it clearer what formats are supported.
- "Left" / "Right" river banks - extend to any two columns.
- What the deal with how the centreline is defined? From the sea? or a check for which is closest to the ocean contours?
- Supported wetted area in place of left/right banks.
