IDENTIFICATION OF WATER INUNDATION USING QUICKBIRD AND ALOS PALSAR SATELLITE IMAGE STUDY CASE: DAYEUHKOLOT SUBDISTRICT, BANDUNG DISTRICT
Ketut Wikantika · 2018
Indonesia was one of many disasterous potential country, more than 70% of natural disaster happened were hidrometeorogical disaster including flood. Flood is defined as an overflow or inundation that comes from a river or other body of water and causes or threatens damage, any relatively high stream flow over topping the natural or artificial banks in any reach of a stream. There are 4 regions in Java Island that have the highest potential of flood, they are Jakarta Province, Merapi Slope Area, Bengawan Solo and Citarum Watershed Area. The purpose of this study is to identify land cover and water inundation of the study area using Quickbird and ALOS PALSAR image. Before classified and analyze the result, image pre-processing has to be generated in Quickbird and ALOS PALSAR image data to rid off the distorsion from the data. Quickbird Image can be used for land cover identification with generated object based image classification and ALOS PALSAR Image are applied to identify water inundation in flood area using backscatter value deliniation. By 10th September 2013 with only 5 mm, all of the classes were inundated by water at several values.
