| Worldview-2 is the first very high resolution satellite imagery that has the ability to acquire data of eight bands named: Coastal (400--450 nm), Blue (450--510 nm), Green (510--580 nm), Yellow (585--25 nm), Red (630--690 nm), Red Edge (705--45 nm), Near Infrared(NIR) 1 (770--895 nm) and Near Infrared (NIR) 2 (860--040 nm). Furthermore, five of these bands---Coastal Blue, yellow, red edge and NIR 2 are the new bands in WorldView-2 that are capable of extracting new features that were not possible with previous satellite imagery. Accurate and upto- date bathymetric models are an effective tool for gaining a clearer understanding of the world's waterways, and thus play an important role in many marine applications such as navigation. In this research, the automatic feature extraction technique will be used to locate water area edges. A threshold mask will then be used to determine small land and ships inside the shallow water area. An assessment will be done for all the eight bands to show their contribution to the bathymetry application and shore edge and shallow water outlining, with an emphasis on the yellow and Coastal bands. The conclusion and recommendation will be based on a statistical analysis of the comparison between Worldview-2 data and DEM data for the same area of interest. |
