Satellite imagery as an aid to flood zone mapping

Many river basins in Malaysia are frequently affected by floods, which caused an average loss of about US$40 million annually. A number of measures, structural and non-structural, were adopted recently in an effort to reduce the flood damages. One of the methods involves developing flood risk maps w...
