Rosenau, R., R. Dietrich, and M. Baessler. 2012. Temporal flow variations of major outlet glaciers in Greenland using Landsat data. 2012 IEEE International Geoscience and Remote Sensing Symposium, Munich, 2012, 1557-1560. doi: 10.1109/IGARSS.2012.6351100.This data set, part of the NASA Making Earth System Data Records for Use in Research Environments (MEaSUREs) program, consists of mean monthly velocity maps for selected glacier outlet areas. The maps are generated by tracking visible features between optical image pairs acquired by the Landsat 4 and 5 Thematic Mapper (TM), the Landsat 7 Enhanced Thematic Mapper Plus (ETM+), the Landsat 8 Operational Land Imager (OLI), and the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER).

• This update utilizes a new feature tracking algorithm within the Surface Extraction through TIN Searchspace Minimization (SETSM) software package, adopted because it is open source and optimized for high-performance computing environments.
• This update only uses Landsat 8 OLI imagery
• For data from 01 January 2016 onwards there is one additional geoTIFF available for velocity magnitude, (vv).NSIDCMinor VersionNSIDCCurrent Version1NSIDCSpatial Reference SystemsEPSG:3413WGS 84 / NSIDC Sea Ice Polar Stereographic NorthNSIDCLevel of ServiceComprehensiveNSIDCFull Dataset CitationHowat, I. 2020. <i>MEaSUREs Greenland Ice Velocity: Selected Glacier Site Velocity Maps from Optical Images.</i> Version 3.
