the first scientific quality datasets were acquired in November 2014. The Sentinel satellite missions are designed, launched and operated as a result of close collaboration between ESA, the European Commission, industry, service providers and data users.

For inquiries of a scientific nature, please contact:. Through this data portal, we distribute frequent maps of ice velocity for key outlet glaciers of the Antarctic and Greenland ice sheets in near real time. Gridded ice speeds are provided in geotiff format from a smaller extracted area across the central trunk of each ice stream, with a 100 metre by 100 metre grid spacing. We will not pass on your details to anyone else.

Due to differences in the speed with which the satellite data and precise orbit information can be generated and delivered, some image pairs may have been processed using the standard metadata, rather than the precise orbit information.

A corresponding error dataset is also provided in geotiff format as a relative measure of the data quality. All the specified data delivered by VelocityMeter can be read/use by any MetaTrader 4 Expert Advisors (EA). The velocity maps are produced by tracking moving features in synthetic aperture radar data acquired by the European Space Agency's Sentinel-1 satellite.
