Abstract

Bathymetry is information on the depth of the sea that can describe the hydrographic conditions of the seabed. Satellite derived bathymetry has several methods that can be applied to the batimetric extraction process using optical satellite images. One of the satellite images that can be used is SPOT 7. The image is the latest generation of SPOT which has 4 multispectral channels with a spatial resolution of 6 meters so that it can be extracted to obtain information on shallow water bathymetry. The bathymetry extraction method uses the Van Hengel and Spitzer methods, 1991. The VS method is the principal component analysis method of three bands with respect to the rotation transformation factor. The purpose of this study is to extract SPOT 7 satellite image data to produce relative bathymetry information in shallow seas using the VS algorithm. The location of the study was carried out on Karimunjawa Island, Jepara Regency, Central Java. The data used is SPOT 7 imagery that was acquired May 18, 2017. The extraction algorithm is used the VS 1991 method. The results show that from SPOT 7 images produce depth index values ranging from 0.0985 to 0.6378.
