There are no file naming conventions for the supply of metadata, however it is recommended that a shortened Survey name or title be concatenated with clearly with a metadata label.
e.g RVInvestigatorVoyageIN2019_T03_Metadata.csv or RVInvestigatorVoyageIN2019_T03.metaThe required ‘L0 MBES line’ naming convention is as follows:
Survey line number, date, time, vessel name and sensor in the following format:
####_yyyymmdd_hhmmss_vesselname_sensor.*
e.g.: 1342_20020602_232433_Solander_EM2040C.all
Where #### is the sequential survey line number, yyyy is the year, mm is the month, dd is the date, hh is the hour, mm is the minute, ss is the second, vessel name is the vessel name, sensor is the specific Multibeam senor model, * is the raw file extension (usually specific to the sonar system). All these information are assigned automatically by the acquisition software such as Seafloor Information System (SIS) and Teledyne PDS.
The survey line numbers must be continuous and sequential and must not be reset during the survey. The purpose of the sequential number is to provide a check that all data files have been preserved and to provide an indication of where logging was stopped and restarted.
After a system restart, manually set the line number counter to the last sequence number +1 before restarting logging.
It is not necessary to have the sub area in the file name.
If single and dual head installations are both used in one survey, the string 'dual' should be appended to the appropriate file name.
Calibration lines should be included in the numbering sequence.
If the survey is divided into two legs, the file sequence should not be reset but remain continuous and uninterrupted.
