Ice Velocity Map
We present a reference, comprehensive, high-resolution, digital mo- saic of ice motion in Antarctica assembled from multiple satellite interferometric synthetic-aperture radar data acquired during the International Polar Year 2007-2009.

Caption: Antarctic ice velocity derived from ALOS PALSAR, Envisat ASAR, RADARSAT- 2 and ERS-1/2 satellite radar interferometry color coded on a logarithmic scale and over- laid on a MODIS mosaic of Antarctica. Projection is polar stereographic at 71oS secant plane.
This data set provides the first comprehensive, high-resolution, digital mosaic of ice motion in Antarctica assembled from multiple satellite interferometric synthetic-aperture radar data. Data were acquired during the International Polar Year 2007 to 2009. This map was built from spring 2009 data from the Canadian Space Agency (CSA)'s and MacDonald, Dettwiler and Associates Ltd. (MDA)'s RADARSAT-2, spring 2007-2008-2009 data from European Space Agency (ESA)'s Envisat ASAR, and fall 2007-2008 data from the Japan Aerospace Exploration Agency (JAXA)'s Advanced Land Observing Satellite (ALOS) PALSAR provided by the Alaska Satellite Facility, complemented by patches of CSA's RADARSAT-1 data from fall 2000 and ESA's Earth Remote Sensing Satellites ERS-1/2 data from spring 1996. Each radar instrument contributes its unique coverage and performance level. The final mosaic assembles 900 satellite tracks and more than 3,000 orbits of radar data.
