The Comparison of Bathymetric Estimation from Three High Resolution Satellite Imagery

This Study was using three high resolution satellite imagery to estimate bathymetric condition at shollow water coral reef environment around Pulau Panggang, Jakarta. The Worldviww 2 supplay 2 m spasial resolution with 8 spectral band, whereas Quikbird 2 produce 2.44 m spatial resolution in 4 spectral and and ALOS produce 10 m spasial resolution with also 4 spectral band. Red band of ALOS and Quickbird hae high correlation with sand depth and the lowest are blue bands. Among this bands, Quickbird red band is the highest and its blue band is the lowest. Worldview visible bands may have low sand depth correlation because of noise from ripple wave during acquisition. This study shown that, Quickbird image is proven able to map water depth variation up to 8 metre at reef flat and lagoon area of Panggang island, Jakarta with RMSe is 1.1 metre. The result also shown on oppoertunity to implement this approch to bathymetric mapping of shallow water area at remote small islands. Proceedings International Seminar on Hydrography. Hal. 1-11
