The vessel file (HVF) in HIPS and SIPS describes the location and calibration of sensor equipment installed on the survey vessel. It defines the offsets and any associated error estimates for each of the sensors.
For a description of the coordinate system upon which the vessel configuration is based, see Vessel Coordinate System.
The HVF is created in the HIPS Vessel Editor, and saved to the folder …\HDCS_Data\VesselConfig.
If you create other data directories, the name of the VesselConfig folder must not be changed and it always has to be located inside the Raw Data directory on the same level as the project directories.
In previous versions of HIPS and SIPS, a text file called the Vessel Configuration File (VCF) was used. VCF files can still be opened and edited in Vessel Editor, but when the file is re-saved, it is converted to HVF format. |
The HVF is divided into a number of distinct sections, each describing one type of sensor. The sections are time-tagged and multiple entries can be defined for different time periods. These entries can be edited in the Vessel Editor.
During the Merge process, corrected sensor data is combined with the observed data to create a final position/depth record.
