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.
