Hintereisferner (Ötztal, Tyrol, Austria) Digital Elevation Models (10 x 10 m) from Airborne Laser Scanning Data Set 2001-2013, links to GeoTIFFs

DOI

The data set consists of 21 digital elevation models (DEM) with a cell size of 10x10 m. The DEMs are generated on base of Airborne Laser Scanning (ALS) data which were acquired in the period of time from 2001 to 2013. The ALS measurements are mainly used to study the volume changes of Hintereisferner complementary to direct glaciological mass balance measurements. Hence, at least one scan was performed close to the end of the glacier mass balance year (end of September) each year. In the glacier mass balance years 2001/2002, 2002/2003, 2007/2008, 2008/2009 and 2010/2011 project-based intermediate campaigns were carried out too. An overview of the data with information about flight dates, used sensors, mean flight heights above ground [m], pulse repetition rates [Hz], across track overlaps [%], mean point densities [points per square meter], vertical accuracies [m] and projections is given in the attached table below.At first 1x1 m DEMs are generated using a simple approach, that calculates the z-value (altitude) from the mean z-value by excluding 5 % of the smallest and largest observations of the ALS points which fall inside the respective grid cells. For the provision of the GeoTIFF (UTM32N) raster files the high resolution DEMs are resampled to DEMs with a cell size of 10x10 m with the bilinear interpolation method, which is implemented in SAGA (http://www.saga-gis.org). If higher resolution DEMs are required or other question arise we would like to ask you to contact the principal investigator.
