Abstract :
The conventional method of detecting flood extent using satellite SAR data is derived from signal intensity changes for each pixel between before and during the flood time. SAR signal intensity should include the information of interaction between ground features and microwave radar. Using mathematical morphology, particular ground feature can be investigated, such as regularly straight lined levees of consolidated paddy fields.
