This dataset contains a polygon of the active floodplain along the German interior parts of the River Elbe from the Czech border to the weir in Geesthacht in the coordinate reference system ETRS 1989 UTM 33N.
Originally, this polygon was produced for the floodplain status report (Auenzustandsbericht; Brunotte et al. (2009), Bundesamt für Naturschutz (2009)) at a scale of 1:25,000. For hydflood it was updated with recent flood protection measures and manually improved with recent digital elevation models and aerial images at a scale of < 1:10,000.
