The Austrian glacier inventories of 1969 and 1998 have been updated by combining hill shades with different illumination angles calculated from LiDAR DEMs and by comparison with orthophoto data, where available. The data was recorded between 2004 and 2012. The accuracy of the areas derived by the LiDAR method to ±1.5 % for glaciers larger than 1 km² and up to ±5% for smaller ones. The comparison with glacier margins measured by DGPS in the field for 118 points showed that 95% of these glacier margins derived from LiDAR were within an 8 m radius of the measured points and 85% within a 4 m radius. The ice divides remain unchanged in all glacier inventories and are defined from the glacier surface in 1998. No size limit was applied for the mapping of glaciers in the 2006 inventory, i.e. glaciers whose area has decreased below a certain limit are still included in the updated inventory.
