Bedrock elevation model

The national bedrock elevation model represents the bedrock surface, which also corresponds to the base of the unconsolidated deposits. The model has a 10 x 10 m raster cell size and shows the altitude in meters above sea level. The bedrock elevation model (BEM) is part of the larger swissBEDROCK dataset, which also includes the <a href=" https://map.geo.admin.ch/?layers=ch.swisstopo.geologie-lockergestein_maechtigkeitsmodell&topic=geol" target="_blank">thickness model of unconsolidated deposits (TMUD)</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.
