MEaSUREs ITS_LIVE Regional Glacier and Ice Sheet Surface Velocities, Version 1

This data set from the Inter-Mission Time Series of Land Ice Velocity and Elevation (ITS_LIVE) project, part of NASA's Making Earth System Data Records for Use in Research Environments (MEaSUREs) Program, consists of regionally compiled, mean annual surface velocities for major glacier-covered regions, derived from Landsat 4, 5, 7, and 8 imagery. Data are available from 1985 to 2018. Data availability is significantly limited prior to 2013 due to image scarcity and low image quality, however annual coverage is nearly complete for the years following the Landsat 8 launch in 2013.
