AusSeabed Data Types
Through the delivery of the Data Hub, AusSeabed will facilitate access to a range of seabed information associated with its identified product suites. The data types, listed in order of priority, are:
Bathymetry data
Backscatter (seafloor and water column) data
Sediment sample data
Sub-bottom profile data
Each data type will have an associated product suite, all of which will be stored, managed and delivered through the AusSeabed data hub. At this time, the AusSeabed Data Hub is accepting bathymetry data, with the subsequent data types to come online at a later date.
At this time, AusSeabed is accepting bathymetry data according to the following table:
Data Level | Notes | AusSeabed Hub | |
Data Requirements | Required Metadata for Submission | ||
L0 | L0 – Raw Data L0 data is native format, as recorded by the sensor. It should include all necessary datagrams required for a comprehensive bathymetry and backscatter processing, including raw backscatter per beam (BA) and raw backscatter in time series (TS), and all required ancillary data. Water column data if collected should be stored in a separate file. | · MBES proprietary format e.g. *. all for Kongsberg, *.s7k for Reson and *.gsf (possibly .XTF) for all other MBES system including R2Sonic · WC over wrecks (*.wcd) · Applanix POSMV or proprietary format of any aux sensor used e.g. TerraPos, Starfix etc | <Insert link> |
L1 | L1 – Georeferenced Point Data - uncleaned L1 Data is raw data processed to form a georeferenced bathymetric point cloud with no cleaning | Nil |
|
L2 | L2 – Georeferenced Point Data – Fully Cleaned L2 data will be cleaned relative to the CUBE Surface. | · MBES: HDCS (LAT) plus backscatter · SVP: *.svp or *.asvp or *.txt (of those used to produce L2) · Tide: *.tid or (*.zdf & *.tid) · Navigation SBET | <Insert link> |
L3 v.0 | L3 Gridded Final Survey Product data L3 is the delivered Final Survey Data for a survey. L3 will be a CSAR CUBE / SDTP surface, which will include density and uncertainty. | Nil | <Insert link> |
L3 v.1 | L4 – Verified Final Survey Data L4 Data is the final Survey Surface that is verified and accepted by the contributing organisation. | · BAG single-resolution (MSL)
