description: This dataset provides a 100-metre resolution map of intrinsic ground risk across Switzerland, intended to support the Specific Operations Risk Assessment (SORA) required under EU regulation (EU) 2019/947 Article 11 for drone flights in the Specific category. The map estimates risk to uninvolved people on the ground who might be overflown by unmanned aircraft, based on population density and land use characteristics. It is published by the Federal Office of Civil Aviation (Bundesamt für Zivilluftfahrt, BAZL) of the Swiss Confederation and is used by drone operators and authorities to assess and document ground risk as part of SORA-based operational authorisations for unmanned aircraft systems.
