Add patch option/step #252

Closed rosepearson closed 4 months ago

rosepearson commented 5 months ago

Add a step for patching in any generic raster grid.

This is an issue derived from: https://github.com/rosepearson/GeoFabrics/issues/231

Also add support for patching where you remove an area and interpolated between. This could be by specifying a polygon (e.g. buffered around stopbanks) to remove, to see the impact of no flood infrastructure for instance. Could be this case or a separate one.

Example of a raster patch / patches to include in the form of an adjusted river bed vertical alignment.

Note in future:

[ ] Decide if use a separate 'data_source' layer for the z and zo layers. Currently it is updated regarless of which layer is patched.
[ ] Ensure the 'PatchDemGenerator' and other relevant information is added to the DEM
