No installation needed; it runs entirely in your browser.
Aggregate land cover area (m²) per Swiss cadastral parcel from official Amtliche Vermessung (AV) data — supports single-parcel EGRID lookup and full municipal batch processing.
For each parcel, the tool clips every intersecting land cover polygon to the parcel boundary and computes the area of each piece — a per-parcel breakdown of how much area each land cover type covers, classified by SIA 416, DIN 277, green space, imperviousness, and VBS categories.
The same analysis is available three ways. Each has its own README with full details.
Zero-install browser app: upload a CSV of parcels and explore per-parcel land cover on an interactive map, with export to CSV/Excel/GeoJSON. Multilingual (DE/FR/IT/EN).

Data coverage note: The Web App uses the geodienste.ch WFS, which requires cantonal approval in 6 cantons (JU, LU, NE, NW, OW, VD). Parcels in these cantons are found by EGRID but return 0 m² land cover. Coverage is also incomplete in TI, VS, and NE. The Python CLI has full coverage from a local GeoPackage. See the User Guide for details.
