How can I extract the floodwater from satellite images? Is the image classification method accurate for moderate-resolution satellite (Terra/Aqua MODIS)? Or are there more accurate methods?

    In the UK Insurance industry the accuracy needs to be +/-10 meters. So that 1:15, 1:25, 1:50 & 1:100 year flood plains can be modeled. Also based on historical facts/extents – Mapperz Oct 30 '13 at 16:12
