Bedrock elevation model

The bedrock elevation model is a complete model of the bedrock surface in the Molasse Basin, the larger Alpine valleys and portions of the Jura Mountains. This digital model has a 25-m grid spacing and shows the altitude in metres above sea level.


Thickness model of unconsolidated deposits

The thickness model of unconsolidated deposits is a digital data set that describes the thickness of the unconsolidated deposits. The subtraction of the bedrock surface from the terrain surface (digital height model, DHM25) gives the thickness of unconsolidated deposits.
