Land use within flood hazard areas in EU countries (dataset)

Abstract

The dataset presents the extent of areas exposed to flooding with a Q100 (p=1% probability of flood occurrence) for selected regions of Slovakia and Germany. The Slovak component is provided as a vector layer (ESRI Shapefile) in the form of lines (LineString) representing boundaries/segments of the Q100 flood extent (file Q100P.zip, 14,538 features, reference system S-JTSK / Krovak East North – EPSG:5514). The German component is delivered as a dBASE (.dbf) attribute table (Q100_od_rzek_Niemcy.dbf, 103,351 records) linked to polygon geometry (the table includes fields such as SHAPE_Area and SHAPE_Leng); however, the provided file contains no geometry and no coordinate reference system information. The data can be used for flood risk analyses, spatial planning, environmental impact assessments, exposure modelling of infrastructure and population, and cross-border comparisons. The dataset is intended for reference purposes and requires verification against primary sources and local hydrological conditions; it is not intended for real-time operational use.
