Coasts in cold climate regions are occupied by ice several months per year. In Canada, 90% of the coastline is affected by seasonal or multi-year sea ice. Active radar remote sensing provides the most efficient way to map ice at various space and time scales. The Canadian RADARSAT-2 satellite provides some of the most important data for ship navigation in ice-rich waters. The radar imagery can be useful in regions where high-resolution maps of shore ice are needed for winter transportation or for recreational activities.
