Imagenex Raw Data

Revision History

- Date: Second release (beta designation removed)
Formats
These files are available as a .raw binary data format. For use of these data products, navigation data are needed. These can be manually inputted from the ROPOS navigation device (23239) or .837 files are also available with the navigation imbedded in the raw files. There is one .837 file for every .raw file in the database. Following addition of navigation data, 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)
