In the header of each HYPACK file, DEV3 is erroneously labeled as "F190" however the system used was really the Coda F180 RTK-GPS.
How reliable are the data what problems remain in the data set? Person who carried out this What similar or related data should the user be aware of? Times are recorded in UTC (Coordinate Universal Time). For example, filename 015_1239.260 represents planned survey HYPACK line number 015, start time 1239 and Julian Day 260. The filenames are in the format of linenumber_starttime.julianday. Raw HYPACK navigation files were transferred from the navigation acquisition computer to a centralized data server on the survey vessel for accessibility and archival.
The antenna for the RTK-GPS was located on the same pole that the SWATHplus-M sonar was mounted (on the ship's bow). Times were recorded in UTC (Coordinate Universal Time). Raw navigation data were saved in HYPACK format (File name convention is LLL_TTTT.DDD, where LLL is the user defined planned HYPACK line number, TTTT is the 24-hour time for the beginning of the file, and DDD is the Julian day (JD). Data collected during the 2012 survey can be obtained here. More information can be found on the web page for the Woods Hole Coastal and Marine Science Center field activity. These survey data are used to characterize the riverbed by identifying sediment-texture and riverbed morphology. Sediment grab samples were collected at 72 of the 88 sampling sites, video was acquired at 68 sites, and photographs of the river bottom were taken at 38 sites. Approximately 230 linear kilometers of digital Chirp subbottom (seismic-reflection) and 234-kilohertz interferometric sonar (bathymetric and backscatter) data were collected along with sediment samples, riverbed photographs, and (or) video at 88 sites within the geophysical survey area.
HYPACK GPS ECHO SOUNDER SET UP SOFTWARE
Text files of the navigation logged with HYPACK Software during field activity 2012-024-FA in 2012 by the U.S. Ideal for shallow water surveys on USV/ASV/ROV and dual head deployment.Text files of the navigation logged with HYPACK Software during field activity 2012-024-FA in 2012 by the U.S. The M3 Sonar has the ability to produce real-time 3D point clouds enabling fast target or object detection.
HYPACK GPS ECHO SOUNDER SET UP WINDOWS
The system allows the operator to interleave active pings and passive listening modes, Doppler, multiple true-zoom windows (up to 4) with linear FM and CW imaging modes of operation.ĭata outputs are compatible with various third party software such as Caris, EIVA, Hypack and QINSy. The M3 Sonar has the ability to configure applications using complex pulses. Unique to the M3 Sonar is the patented eIQ (enhanced image quality) mode of operation that generates multibeam images with unprecedented clarity. The innovative design of the M3 Sonar uses two sets of complementary transducers which allow it to generate both imaging and bathymetric data with the same head. Provides GeoTIFF output and creates real-time mosaic using third party software
Produces single-beam image quality with the speed of multibeam Generates imaging and bathymetric datasets from one sonar head Portable, cost effective and light weight sonar
