Our Operational Ice Maps product is a combination of radar, optical
and sea ice concentration data, plotted with the appropriate
landmasks and output in an image format for easy viewing on any device.
Separate image files are delivered for each type of satellite imagery.
An example for the Kara Gate region is shown in the image below:
Radar images are produced by combining the output of one or more Synthetic Aperture Radar (SAR) scenes from the Sentinel-1 satellites and extracting the data for the desired region of interest. Image data is delivered as GeoTIFF, an image format that includes geographical information and can thus be used in Geographic Information Systems (GIS) software packages.
The optical data product that we deliver is based upon the MODIS Terra Corrected Reflectance (True Color) optical satellite data kindly made available by the NASA. The relevant data is extracted for the desired region of interest and delivered as GeoTIFF, an image format that includes geographical information and can thus be used in Geographic Information Systems (GIS) software packages.
