Land cover

Description
This step aims to select target features from land cover layer (such as natural areas).

Parameters
Land cover layer must cover the whole study area but it might be necessary to use a larger extent when using CBC method (see step 4) to mitigate "boundary problem".
Input data can be clipped to decrease processing execution time.
Selection mode By field values automatically extracts land cover classes from specified field. Classes to select must be checked. Description field contains land cover classes description and is optional.
If selection criteria is more complex (depending on several field for instance), By expression mode must be used and corresponding expression specified.

Results
Launch selection by clicking corresponding button. Features are selected and then dissolved (dissolve process can be very slow for huge territories). Result layer is loaded in QGIS and stored in Workspace/outputs/landuseSelectionDissolve.gpkg file.
