Element | Value |
GAID or SurveyID | The GA SurveyID or the Source SurveyID for example GA-0123 or CSIRO in2019_e01 |
Product Type |
Backscatter |
Survey Year (Optional) | Year the Survey commenced (optional) as sometimes this information is visible within the SurveyID e.g. 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) | e.g. EM122_ |
GEOCODER-TS, EM122 |
_GEOCODER-BA, EM710_SIPS-BA. (Identifier may include raster algorithm-backscatter type, or |
band contents. TS=Time Series/Snippets. BA=Beam Average) | |
RegionCode | Each Survey will be broken up into one or more Region Codes based on xxx grid definition. |
MeasurementLabel | e.g |
Intensity | |
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 *.shp – Shapefile coverage holding geometry and key attributes |

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