The following Pre-processing steps were applied:\n1.  Radiometric Correction: Digital Numbers converted to TOA Reflectance\n2.  Atmospheric Correction: Dark Object Subtraction\n3.  Masking: Masking of Land and Ice features using classification of accompanying PAN imagery\n4.  Shallow Water Masking: Deep water masked out by thresh-holding the green and yellow bands\nThe pre-processed data is provided as an 8-band Geotiff in UTM 44s with pixels of 2 m. \n\nSatellite-derived bathymetry grid [Davis Station_SDB_utm44s_alat.tiff]\nThis bathymetry dataset was produced by applying the SMART-SDB model to Worldview 2 Multispectral Image acquired on 20120118 at 04:52:17Z. Multibeam bathymetry data acquired in February-March 20101 using a Kongsberg EM 3002D MBES, with vertical and horizontal accuracy of 0.38m and 1.95m respectively, was used for both calibration and validation of the SMART-SDB model.
