Buildability
tr_buildability
What it does
Weighted buildability score (slope, equator-facing aspect, elevation limits) with the steep and optional wet ground excluded.
Like Suitability Modeler / Weighted Overlay in ArcGIS Pro and Raster calculator (weighted overlay) in QGIS. Run by the product's terrain engine on 30 m cells from Copernicus DEM GLO-30 (full resolution): 740 x 930 = 688,200 cells; no model was called.
Buildability
Buildability: 41.9% optimal, 30.8% suitable; mean score 67/100; 17.0% excluded by constraints.

Notes
- DEM: Copernicus DEM GLO-30 (open data; cached). Copernicus DEM GLO-30: produced using Copernicus WorldDEM-30 (c) DLR e.V. 2010-2014 and (c) Airbus Defence and Space GmbH 2014-2018 provided under COPERNICUS by the European Union and ESA
- the grid (30 m) is finer than the DEM (30.9 m): values between DEM samples are interpolated
