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
* SPOT5, 13 September 2007
* ASTER, 30 September 2017
* SPOT7, 1 October 2018

The original SPOT5 DEM was obtained from the SPIRIT project (Korona et al., 2009)
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 & Brun (2019)

* SPOT5 data were obtained thanks to funding from CNES during the fourth international polar year.
* 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.
* ASTER data were provided by NASA (U.S.) and METI (Japan).
