- Input: 1 m DEM, AOI, 42 polygonal and 10 linear water features
- Parameterised result: 50 m base test, 3° terrain threshold, selective extension toward 100 m
The derived layers are analytical screening outputs, not official or legally established boundaries. They do not replace land-management documentation, object classification, field verification, or a competent authority’s decision.

Download the original inputs
- Complete source archive, dataset 2 (ZIP, 14 MB)
- Area of interest (GeoPackage)
- Digital elevation model, 1 m (GeoTIFF, 22 MB)
- Polygonal and linear water objects (GeoPackage)
The archive and individual files are redistributed so this pilot can test both a self-contained download and a source-repository workflow.

Class 1 is the 50 m standard-width screening zone. Class 2 is the additional terrain-triggered extension between 50 and 100 m. The run produced 0.756 km² of class 1 and 0.411 km² of class 2.

The original .model3 file is redistributed unchanged. It expects a QGIS project context because it uses ProjectCrs and @project_folder. The published Python build uses the documented shoreline-distance, nearest elevation, 3° threshold and selective-extension logic to create the compact web derivatives efficiently on this nettop.
Provenance and limitations
The source materials come from the oleksaboiko/pzs_method repository. This portal packages repository method version 1.0.0 with dataset_2.zip and records exact checksums.
The source water attributes do not legally classify each object, so the 50 m base width is an explicit test parameter. Data currency, positional accuracy, terrain accuracy and legal applicability have not been independently certified by the portal. Any correction must be published as a new immutable version.
