An easy to use ArcMap based texture analysis program for extraction of flooded areas from TerraSAR-X satellite image

Extraction of the flooded areas from synthetic aperture radar (SAR) and especially TerraSAR-X data is one of the most challenging tasks in the flood management and planning. SAR data due to its high spatial resolution and its capability of all weather conditions makes a proper choice for tropical co...
