Horizontal position of the launches acquiring multibeam bathymetry were determined using GPS corrected by U.S. Coast Guard differential GPS beacon stations at Moriches, NY, Sandy Hook, NJ, and Acushnet, MA. Real-time positioning during LIDAR acquisition was obtained by an Ashtech GG24 GPS receiver combined with Thales GeoSolutions Wide Area DGPS. Original horizontal resolution of the MBES data was 0.5 - 2 m; original cell size of the gridded LIDAR data was primarily 4 m. The final CARIS combined base surfaces for the MBES data were produced at a 2-m cell size; final cell size of the gridded LIDAR data was 4 m.
Attitude of the launches (e.g. pitch, roll, and heave) acquiring multibeam bathymetry were monitored by an Applanix TSS POS/MV 320 Version 3 GPS aided navigation system. Real-time positioning during LIDAR acquisition was obtained by an Ashtech GG24 GPS receiver combined with Thales GeoSolutions Wide Area DGPS. Ashtech Z12 GPS receivers, provided as part of the Airborne System and Ground Systems, also logged GPS data on the aircraft and at a locally established base station to provide post processed KGPS position solutions. Received infrared laser energy, supplemented by an Altitude Heading Reference System (AHRS) inertial height reference and kinematic GPS, determined the height of the aircraft. Verified water levels are based on NWLON stations 8461490, New London, CT and 8465705, New Haven, CT. The vertical resolution of the multibeam data is approximately 0.5% of the water depth.
All collected data were processed and used to produce this dataset.
