Acoustic backscatter gridded data for the Lido inlet, Venice Lagoon, (2016 survey)

This high-resolution (0.5m resolution) gridded backscatter data set was collected during April and May 2016 in the Lido inlet (Venice Lagoon) using a Kongsberg Simrad EM 3002 Compact single-head MBES system and a Kongsberg EM 2040 Compact dual-head MBES system. The operational frequency for this survey was set at 360 kHz for the EM 3002 system and at 320 kHz for the Kongsberg EM 2040 system. A Seapath 330 positioning system with a Fugro HP DGNSS corrections was used for ship positioning with the Kongsberg EM 3002 system and a Seapath 300 system supplied by a Fugro HP DGPS was used for ship positioning with the Kongsberg EM 2040 system. The data was collected aboard small boat MBF1213 of the Hydrographic Office of Italian Navy and aboard small boat Litus, operated by CNR-ISMAR. The backscatter data was processed with the Fledermaus Geocoder Toolbox (FMGT) software. The data file is in the ESRI ASCII grid format, WGS-84, UTM zone 33N. Funding for this study came from the Italian Ministry of University and Research RITMARE Flagship Project.

本高分辨率（0.5米分辨率）的栅格式后向散射数据集，系于2016年4月至5月期间，在里多湾口（威尼斯潟湖）采用康斯伯格·西蒙拉德的EM 3002紧凑型单头多波束测深系统及EM 2040紧凑型双头多波束测深系统采集而成。此次调查的操作频率分别为EM 3002系统360千赫兹和Kongsberg EM 2040系统320千赫兹。船舶定位方面，使用配备Fugro HP DGNSS校正的Seapath 330定位系统配合Kongsberg EM 3002系统，以及由Fugro HP DGPS供应的Seapath 300系统配合Kongsberg EM 2040系统。数据采集于意大利海军海道测量局的小型船只MBF1213以及由CNR-ISMAR运营的小型船只Litus上。后向散射数据经过Fledermaus Geocoder Toolbox（FMGT）软件处理。数据文件格式为ESRI ASCII网格，采用WGS-84坐标系，UTM区33N。本研究的资助来自意大利教育和研究部RITMARE旗舰项目。
