Thickness model of unconsolidated deposits

The national thickness model of unconsolidated deposits describes the thickness of the unconsolidated deposits in meters with a 10 x 10 m raster cell size. This product is derived from the bedrock elevation model. The subtraction of the bedrock surface from the base terrain model provides the thickness of the unconsolidated deposits. The base terrain is a combination of <a href=" https://www.swisstopo.admin.ch/en/height-model-swissalti3d" target="_blank">swissALTI3D</a>, <a href=" https://www.swisstopo.admin.ch/en/height-model-swissbathy3d" target="_blank">swissBATHY3D</a> and the <a href=" https://www.glamos.ch/en/#/A50d-01" target="_blank">GLAMOS</a> glacier base. The thickness model of unconsolidated deposits is part of the larger swissBEDROCK dataset, which also includes the <a href=" https://map.geo.admin.ch/?layers=ch.swisstopo.geologie-felsoberflaeche_hoehenmodell&topic=geol" target="_blank">bedrock elevation model (BEM)</a>, uncertainty estimates, and changes compared to previous versions. The full swissBEDROCK dataset can be <a href=" https://www.swisstopo.admin.ch/en/swissbedrock-en" target="_blank">downloaded here</a> or viewed and queried on <a href=" https://viewer.swissgeol.ch/?lon=8.41012&lat=46.83165&elevation=425641&heading=0&pitch=-90&map=ch.swisstopo.pixelkarte-grau&map_transparency=0.00&layers=ch.swisstopo.swissbedrock-geotiff&layers_visibility=true&layers_transparency=0.50&layers_timestamp=" target="_blank">viewer.swissgeol.ch</a> on a cell basis. The model consists of data provided by third parties and parts that have been modelled by the Federal Office of Topography. A <a href=" https://www.geocat.ch/geonetwork/srv/api/records/f7836146-3f9a-4807-9011-618800409236/attachments/swissBEDROCK_ReleaseNotes_R1.pdf?approved=true" target="_blank">release notes</a> file is provided detailing the origin and characteristics of the various model components. More information on the methodological overview and workflow can be found in the <a href=" https://www.geocat.ch/geonetwork/srv/api/records/f7836146-3f9a-4807-9011-618800409236/attachments/swissBEDROCK_model_description.pdf?approved=true" target="_blank">model description</a>. 3D models represent a simplification of the real geological settings.
