1. Users with the appropriate subscription and a compatible SideScan transducer can generate SideScan mosaics to view them as a layer with contours. The feature is enabled under Processing Preferences or the Web Upload settings. When logging sonar with a SideScan transducer, the SideScan channel information is logged in the *.sl2/3 file format and not *.slg. Generating SideScan layers from previously uploaded sonar files is possible, contact BioBase staff about special processing requests.
