Abstract
Abstract. Landslides are a frequent natural hazard occurring globally in regions with
steep topography. Additionally, landslides play an important role in
landscape evolution by transporting sediment downslope. Landslide inventory
mapping is a common technique to assess the spatial distribution and extent
of landslides in an area of interest. High-resolution digital elevation
models (DEMs) have proven to be useful databases to map landslides in large
areas across different land covers and topography. So far, Denmark had no
national landslide inventory. Here, we create the first comprehensive
national landslide inventory for Denmark derived from a 40 cm resolution DEM
from 2015 supported by several 12.5 cm resolution orthophotos. The landslide
inventory is created based on a manual expert-based mapping approach, and we
implemented a quality control mechanism to assess the completeness of the
inventory. Overall, we mapped 3202 landslide polygons in Denmark with a
level of completeness of 87 %. The complete landslide inventory is

Luetzenburg, 2021) or as a web map (https://data.geus.dk/landskred/, last access: 6 June 2022) for further investigations.
