Overview
This data set consists of velocity maps and error estimates for five surge-type glaciers: Nàłùdäy/Lowell Glacier, Canada; Medvezhiy Glacier, the Pamir mountains; South Rimo Glacier, the Karakoram; Sít' Kusá Glacier, Alaska; and Aavatsmarkbreen Glacier, Spitsbergen, Svalbard.
The maps are generated using CautoRIFT, a pipeline that improves temporal coverage during periods of rapid glacier motion by adding pre-processed, daily high-resolution PlanetScope images and customized feature tracking parameters for each glacier to NASA's autonomous Repeat Image Feature Tracking (autoRIFT) algorithm for Sentinel-2 and Landsat imagery.
Stable surface masks, area of interest (AOI) and glacier outlines, and ancillary data are also available for each glacier site.
