The Swiss Atlas of Physical Properties of Rocks (SAPHYR) project aims at compiling data on physical properties of rocks from Switzerland and surrounding regions (Zappone & Kissling 2021). Mandated by the Swiss Geophysical Commission and the Swiss Geological Survey at swisstopo, we are supporting to integrate new data into the atlas in the framework of this 3rd extension phase. In particular, we are setting up a workflow to harmonise and transfer the data of the ETH Rock Physics and Mechanics Laboratory (RPMLab).
