SPOT5 (2007), ASTER (2016) and SPOT7 (2018) Digital Elevation Models of Little Kluane Glacier (Yukon Territory)

=========================== Authors Etienne BERTHIER LEGOS, Université de Toulouse, CNES, CNRS, IRD, UPS, 31400 Toulouse, France, ===========================<br> 1. Collection This collection contains three digital elevation models (DEMs) of "Little Kluane" Glacier (Yukon Territory, Canada) with an horizontal grid spacing of 30 m<br> * SPOT5, 13 September 2007<br> * ASTER, 30 September 2017<br> * SPOT7, 1 October 2018 The original SPOT5 DEM was obtained from the SPIRIT project (Korona et al., 2009)<br> ASTER and SPOT7 DEMs have been derived using the Ames Stereo Pipeline (Beyer et al., 2018) from stereo images using the set of correlation of parameters in Deschamps-Berger et al. (2020) All DEMs have been coregistered and bias-corrected to the Copernicus 30 m global DEM following the methods of Berthier &amp; Brun (2019) <br> =========================== 2. Dataset Acknowledgement * SPOT5 data were obtained thanks to funding from CNES during the fourth international polar year.<br> * SPOT7 data were obtained thanks to DINAMIS Project, for “Dispositif Institutionnel National d’Approvisionnement Mutualisé en Imagerie Satellitaire”, a French platform that acquires and distributes very high resolution Earth satellite imagery for French and foreign institutional users under specific subscription conditions.<br> * ASTER data were provided by NASA (U.S.) and METI (Japan). =========================== 3.
