Fragmentation

Description
This step aims to integrate fragmentation features to step2 output layer.
For each feature type, selection parameters must be set then saved by clicking button Save selection. Saved parameters are displayed as a new line in visualisation table.

Parameters
Input layer can contain point, line or surface features. Input layer can be clipped as in step2.
Expression: selection expression applied to input features. If expression is empty, all features are selected.
Buffer: buffer expression to modelize physical footprint. Mandatory for punctual and linear data.
Identifier: unique identifier of current selection

Results
Each selection is processed (clip, selection, buffer) and resulting layer (with identifier name) is stored in temporary directory.
These layers are then merged, difference with step2 result is performed and cast to single geometry. Result layer is stored in Workspace/outputs/landuseFragmSingleGeom.gpkg file.
