Ice drift (May 11-29, 2002)
Ice drift determination using satellite imagery
Ice charting with the use of Arc view software
Conclusion
•Satellite imagery is the main source of data on ice conditions in the Arctic, Antarctic and ice covered seas. To increase the reliability of ice information derived from satellite imagery joint processing of the data from different spectral ranges and other data sources has to be applied.
