Comparing the opportunities of Landsat-TM and Aster data for monitoring a debris covered glacier in the Italian Alps within the GLIMS project

Abstract: The difficulties in monitoring partly debris covered glaciers by the application of remote sensing techniques is a well known problem. The use of visible (VIS) and near infrared (NIR) bands does not always provide sufficient information to detect the glaciers margins with remote sensing data. In this study the value of the thermal band for glacier detection is investigated. Particular attention is hereby drawn to the different opportunities of glacier monitoring using LANDSAT-TM and TERRA-ASTER data. Accordanc… Show more

“…Debris thickness on both glaciers was estimated by analysing, according to empirical models, kinetic surface temperature maps (pixel size 90 Â 90 m 2 ) acquired by the ASTER satellite on 5 August 2009 (Belvedere glacier) and 12 August 2009 (Miage glacier) at 10:40 am local solar time (Taschner and Ranzi, 2002;Mihalcea et al, 2008). Annual surface velocity of both glaciers was measured by the differential global positioning system method (Diolaiuti et al, 2005;Caccianiga et al, 2011).…”

“…A pioneer study was undertaken by Lougeay [94], who explored the potential of thermal remote sensing to identify different moraine types and glacier ice based on thermal contrast. The research was verified by Taschner and Ranzi [95], Ranzi et al [96] and Mihalcea et al [97] in the Italian Alps using Landsat TM/ETM+ and ASTER images. These studies revealed that the strongest thermal contrast appears around midday.…”

“…In addition to process studies, large scale mapping of debris cover is important for a realistic estimation of melt water production by debris covered glaciers (Taschner and Ranzi, 2002;Mihalcea et al, 2008a;Hagg et al, 2008). This is best achieved by the use of satellite imagery (Paul et al, 2004;Stokes et al, 2007) and an important aim of a number of studies was the determination of supra-glacial debris thickness using remote sensing information (Mihalcea et al, 2008b;Foster, 2010).…”
