Abstract
Shallow water depth extraction is always a challenging job because they are some of the most dynamic and constantly changing regions of the globe. Here we use World-View-2 Panchromatic and Multispectral Satellite imagery and also ROV(Remotely Operated Vehicle) data and then relate spectral radiance values to ground truth depth data to derive depth for the shallow water region in Andaman and Nicober Island. ROV is comparatively expensive and has less coverage. So with the introduction of World View-2 ‘s higher resolution, increased agility and costal green band, bathymetric measurements will substantially improve both in depth and accuracy, which can be cost effectively used to apply in operations potentially to replace the trend in marine surveying in particular upto 10–20 m Depth.
