Sea Ice Type Concentration from Mizex-87 Sar Data

The SAR is an important remote sensor for sea ice applications both by providing detailed maps of small areas and by producing data for calibration of other sensors, e.g. the microwave radiometer. For these applications sea ice type concentration with a high accuracy (better than 5%) is needed. This accuracy can normally not be obtained by using the individual pixels, but spatial variation (texture) must be taken into account. An investigation of texture measures to improve the discrimination capability of SAR data from MIZEX '87 has been carried out. The classification of the individual ice types is improved considerably by including texture measures, but further development of algorithms is needed to fulfill the requirements.
