Extent of IUCN Global Ecosystem Typology ecosystem functional groups across the marine, freshwater and terrestrial realms in Australia: pre-1750 and 2010-11 to 2023-24

The extent data products in this data collection comprise spatial data describing the distribution of IUCN GET EFGs across the Ecosystem Accounting Area (EAA) defined for national ecosystem accounts for Australia.

The data provided are spatial data in the form of GeoTiff raster files for the majority of IUCN-GET EFGs, with the exception of the Artesian springs and oases EFG (F2.8) within the Lakes biome (vector point data). For all terrestrial EFGs the data cover the pre-1750 time period, as well as an annual time series from 2010–11 to 2023–24.

The data products comprise raster files with one additional vector file:
• Fifteen raster files with a spatial resolution of 100 m represent the majority of EFGs at 15 different time periods: a reference extent (pre-1750 or pre-European), and 14 annual extents from 2010–11 to 2023–24.
• A single raster file with a spatial resolution of 250 m represents the shelf ocean waters biome for a single time period (2023).
• A single raster file with a spatial resolution of 250 m represents the pelagic ocean waters biome for a single time period (2023).
• A point vector representing artesian springs and oases within the lakes biome for a single time period (2022).

These data products meet these specifications:
• Spatial reference: GDA2020 / Australian Albers (EPSG:9473)
• Raster file format: GeoTiff
• Spatial extent: xmin: -2253900, xmax: 2949600, ymin: -5218400, ymax: -929100.

This collection also contains cross-walk files that were used to develop the data products. Cross-walk files define the output EFGs for each ecosystem within source or derived datasets.

These data align with other data prepared for Australia under the NEAP including for biodiversity, ecosystem condition and ecosystem services.
