This document refers to L0 MBES survey data package which contains unprocessed, full resolution MBES data, and Navigation & Attitude and Ancillary data. These data are preferred in native formats of respective sensor systems or in agreed formats (e.g., the Generic Sensor Format (GSF) or the Extended Triton Format (XTF)).

| Bathymetry and backscatter should contain all necessary datagrams required for processing, including raw backscatter per beam (and time series), and all required ancillary data. Water column data is recommended and if possible should be stored in a separate file. |
All preferred formats listed below require essential datagrams/data packets for a complete bathymetry and backscatter processing. Depending on the systems, these datagrams/data packets are called and stored differently. Details of required datagrams/data packets are provided below.
Formats | Required Datagrams/Data packets |
|
*.all, *.kmall, *.mbxx (equivalent MB-System for Kongsberg system) |
|
|
*.s7k, *.mbxx (equivalent MB-System for Reson system) |
|
|
*.xse and others | All essential datagrams/data packets required for a complete bathymetry and backscatter processing requirement
| |
*.gsf (2nd priority) or *.xtf (3rd priority) | Even though they are called and stored differently in their respective format (i.e *.gsf or *.xtf), they must inherit complete datagrams/data packets of their respective parent formats
| |
All supported Navigation & Attitude formats |
|
|
Ancillary (SVP and Tide) in ASCII | SVP
| Tide
|
SVP Position Data | It is a comma delimited text file containing filename of each SVP measurement, longitude, latitude, date and time | |
Tide Position Data | It is comma delimited text file containing filename of each tide time series, longitude, latitude | |
Raw MBES data formats in their proprietary format are strongly recommended unless this cannot be achieved for legitimate reasons. The preferred raw data formats include *.all, *.kmall, *.s7k, *.xse, *.mbxx (equivalent MB-System format). The second preferred raw data format for any systems which do not have their own proprietary format is *.gsf. The third preferred data format is *.xtf (only if other formats are not able to be provided).
Similarly raw Navigation & Attitude data formats in their proprietary formats that most processing software support are strongly recommended e.g. Applanix POSMV, Kongsberg PFreeHeave, Fugro Stratfix and TerraPos.
All ancillary data (SVP and Tide) should be submitted in either ASCII text format or a recognised readable format such as Excel (.xlsx) format or ASCII (.CSV) format converted from the proprietary sensor formats using the software of the corresponding sensor. Where raw data comes from an instrument in a proprietary binary format it must be converted to a readable ASCII format prior to submission.
Submission of all ancillary data is valid only if it is accompanied with separate text files detailing temporal and/or spatial info. For instance, collection of SVP data must be accompanied with a separate text file recording position (latitude and longitude), date and time of each SVP measurement; and collection of Tide data (either observed or predicted) must also be accompanied with a separate text file recording only position of each tide time series. Same principles apply to CTD and XBT-generated SVP.
All preferred formats listed below require essential datagrams/data packets for a complete bathymetry and backscatter processing. Depending on the systems, these datagrams/data packets are called and stored differently. Details of required datagrams/data packets are provided below.
