Description

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).

See <a href="http://nsidc.org/data/measures/gimp">Greenland Ice Mapping Project (GIMP)</a> for related data.

Version Description

Changes in Version 3 apply only to data from 01 January 2016 to the present; data files prior to 2016 are identical to Version 2.1.
• 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).
