Element	Value
GAID or SurveyID	The GA Survey ID or the Source SurveyID for example GA-0123 or CSIRO in2019_e01
Product Type	Bathymetry (for extension to Backscatter)
Survey Year (Optional)	Year the Survey commenced (optional) as sometimes this information is visible within the SurveyID eg. in2019_e01
Resolution - Horizontal	Resolution of grid in metres as per the AusSeabed_DepthRanges_2019 procedure , For fractions such as 0.5m resolution, use - 0p5m
Sensor Identifier (Optional)	eg. EM122_CUBE, EM122_SA (Identifier may include raster algorithm, or Band contents)
RegionCode	Each Survey will be broken up into one or more Region Codes based on xxx grid definition.
MeasurementLabel	e.g Depth, or _Uncertainty, or Density
Version Identifier	Usually considered the production or publication date of the Geotiff: If a date, submit in a standard format using ISO 8601 – {20201214}[{T052921Z}]. Alternatively or additionally use versions numbers e.g v1, v2 etc
Format extension	A standard string defining the format of the product – e.g. .tif - original ov.tif” – overlay (cloud optimised) hs.tif” – Hillshade .shp – Shapefile coverage holding geometry and key attributes

The Vertical datum and CRS were removed as it is available within the broader metadata and does not assist in ensuring uniqueness of the filename.

The Resolution, SensorIdentifier, RegionCode, MeasurementLabel and VersionIdentifier are often required to ensure filename uniqueness when there are multiple options for a single product.
