Land use mapping

This plugin feature offers the functionality to map land use data to Talsim land use categories. Currently, only the mapping of ATKIS land use data is implemented.

Executing the Plugin

The user must provide a folder containing all relevant ATKIS layers (e.g., veg01_f, sie01_f, etc.). The plugin automatically detects the necessary files and merges them into a single land use layer. Optionally, the user can specify a clipping layer to limit the extent of the merged result.

Once merged (and optionally clipped), the plugin maps ATKIS land use types to Talsim-compatible categories using the fields “OBJART_TXT”, “FKT”, and “VEG”.

The output is a GeoPackage containing two land use layers:

• One layer with all land use polygons, where the mapped Talsim land use type is stored in the column “OBJART_NEU”.

• A second, dissolved layer where polygons with the same land use type are aggregated. This layer can be used as input for the HRU Calculation.
