The glacier inventory data set includes shape files of glacier margins for the Austrian Silvretta for the year 2017 (Vorarlberg) and 2018 (Tyrol). The glacier outlines were delineated manually based on older Austrian glacier inventories and high resolution LiDAR data acquired by the Federal Administrations of Tyrol and Vorarlberg. The 46 glaciers of the Austrian Silvretta cover 13.1±0.4 km² in 2017/18, which is only 32±2% of their LIA extent of 40.9±4.1 km². Since the last inventory in 2006, three glaciers were gone.
