An automated, open-source pipeline for mass production of digital elevation models (DEMs) from very-high-resolution commercial stereo satellite imagery
David Shean,Oleg Alexandrov,Zachary Moratto,Benjamin Smith,Ian Joughin,Claire Porter,Paul Morin +6 more
TL;DR: Modifications to the automated, open source NASA Ames Stereo Pipeline to generate digital elevation models (DEMs) and orthoimages from very-high-resolution (VHR) commercial imagery of the Earth include support for rigorous and rational polynomial coefficient (RPC) sensor models, sensor geometry correction, bundle adjustment, and point cloud co-registration.

TL;DR: In this paper, an analysis of satellite imagery, seismic records, numerical model results, and eyewitness videos reveals that ~27x106 m3 of rock and glacier ice collapsed from the steep north face of Ronti Peak.
A systematic, regional assessment of High-Mountain Asia glacier mass balance
David Shean,Shashank Bhushan,Paul Montesano,David R. Rounce,Anthony Arendt,Anthony Arendt,Batuhan Osmanoglu +6 more
TL;DR: In this article, high-resolution digital elevation models (DEMs) from available sub-meter commercial stereo imagery (DigitalGlobe WorldView-1/2/3 and GeoEye-1) acquired over HMA glaciers from 2007-2018 (primarily 2013-2017).

TL;DR: Observations of ground ice exposed by recent impact craters probe the composition of the upper layers of the surface of Mars, and derive ice-table depths that are consistent with models using higher long-term average atmospheric water vapor content than present values.

Glacier Mass Change in High Mountain Asia Through 2100 Using the Open-Source Python Glacier Evolution Model (PyGEM)
TL;DR: In this paper, the authors use a new dataset of geodetic mass balance observations of almost all glaciers in the region to calibrate the Python Glacier Evolution Model (PyGEM) using Bayesian inference.
