Hydromagic allows you to create a sounding from a NMEA0183 logfile which contains both GPS and echosounder data in NMEA0183 format.
This feature has been developed to process logfiles recorded with remotely operated survey boats such as the Z-Boat from Oceanscience.
To load the NMEA0183 data, select the "Import" => "Import NMEA0183 Data..." option from the file menu.
When the tool is displayed, select the logfile and the sentences to be processed and click the "OK" button. A new sounding will be generated from the file.
