MEaSUREs InSAR-based Antarctica Ice Velocity Map, version 2. 450 m resolution. Unit: m/yr.

It is assembled from multiple satellite interferometric synthetic-aperture radar systems. Data was largely acquired during the International Polar Year 2007 to 2009, as well as between 2013 and 2016. Additional data acquired between 1996 and 2016 was used as needed to maximize coverage.

This dataset is part of the NASA Making Earth System Data Records for Use in Research Environments (MEaSUREs) Program.

Original data include x and y velocity components (VX and VY, respectively) projected to EPSG3031. Speed V is calculated as V = sqrt(VX^2 + VY^2).
