Assessment of SRTM, ASTER and IFSAR Digital Elevation Model (DEM) in Oil Palm Plantation River Derivation and Basin Delineation
Digital Elevation Model (DEM) is one of the key hydrological response units (HRU) for flood modelling especially in deriving river network and basin delineation. Three types of DEM were assessed to derive those two parameters; Shuttle Radar Topographic Mission (SRTM), Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) and Interferometric Synthetic Aperture Radar (IFSAR). As for validation process, UAV orthophoto was used to validate the river network and Department of Irrigation and Drainage (DID) catchment data was used to validate the basin. Results revealed that IFSAR DEM provide the most accurate result for deriving river network even without the stream burn-in method. However, due to limited coverage of IFSAR DEM, the basin area is best delineated using SRTM DEM.
