Flood disaster is a major issues due to its frequently events on several areas in Indonesia. Delineation of inundated area caused by flood is needed to support disaster emergency response.

A pair of the data (before and during the flood) were in each observation areas. Observation areas were selected in several location of lowland regions of Java island
