Revision History
- 201203XX: Manufacturer .837 format released
Formats
This data is available in the manufacturer wave packet format (extension is .837).
Manufacturer Format (.837)
This binary wave packet format is specific to the manufacturer. When using Imagenex data acquisition software, data is normally stored in this way and can be post-processed for derived parameters using Imagenex software.
To produce the file, the following requirements apply:
- A new .837 file is started for cabled Imagenex sonars at the beginning of each day or each scan (if rotating)
- A new .837 file is created by the sonar operator for ROV mounted Imagenex sonars at the start of each survey and at desired intervals. These files have had navigation data (latitude, longitude, heading, pitch and roll) added in a post-processing step. The raw files, prior to navigation being added, are also available. Data may be post-processed and gridded using software such as CARIS HIPS and SIPS.
A step-by-step guide is available upon request "Processing the Imagenex Files.pdf" to help with this process.
Surveyed offsets for the creation of a vessel file are attached to this page.
Sound speed profile data may be obtained from the Valeport miniSVS (23326)
