VenetianLagoon_Bathymetry Backscatter:Acoustic
Processed gridded 0.5m-resolution Backscatter Mosaics (GeoTIFF format) from the Lagoon of Venice collected in 2013
This dataset contains high-resolution (0.5m resolution) mosaics of gridded backscatter data (GeoTIFF format). Data was collected during a six-months survey (lasting from May to December 2013) in the channel network of the Venice Lagoon by means of the MBES system Kongsberg EM-2040 Compact dual head. The MBES was mounted on a pole at the bow of the CNR research vessel Litus, a 10-m long boat with only 1.5-m draft. The MBES has 800 beams (400 per swath) 1°x1°; the operational frequency for this survey was set at 360 kHz. A Seapath 300 system was used for ship positioning, improving its accuracy by the correction provided by a Fugro HP differential Global Positioning System (DGPS, accurate up to 0.2 m Backscatter mosaics were created in CARIS HIPS and SIPS through the Geocoder engine. The Geocoder tool automatically corrects the system settings for transmission loss, insonification area and incidence angle variations35. Mosaics were generated using Angle Varying Gain (AVG) correction with a 300-pixel size window and Despeckle
