Dataset developed for the Lake Eyre Basin Bioregional Assessment: Context statement for the Arckaringa subregion.
The following information has been taken from this website.
The initial vegetation data was provided by over 100 individual projects representing the majority of Australia's regional vegetation mapping. State and Territory custodians translated the vegetation descriptions from these datasets into a common attribute framework, the National Vegetation Information System (ESCAVI, 2003). Scales of input mapping ranged from 1:25,000 to 1:5,000,000. These were combined into an Australia-wide set of vector data. Non-terrestrial areas were mostly removed by the State and Territory custodians before supplying the data to the Environmental Resources Information Network (ERIN), Department of Sustainability Environment Water Population and Communities (DSEWPaC).
Each NVIS vegetation description was written to the NVIS XML format file by the custodian, transferred to ERIN and loaded into the NVIS database at ERIN. A considerable number of quality checks were performed automatically by this system to ensure conformity to the NVIS attribute standards (ESCAVI, 2003) and consistency between levels of the NVIS Information Hierarchy within each description. Descriptions for non-vegetation and non-native vegetation mapping codes were transferred via CSV files.
The following website provides a detailed description of the Major Vegetation Groups.
Parts of New South Wales, South Australia, QLD and the ACT have extensive areas of vector "NoData", thus appearing as an inland sea. In the ACT and SA, the vector data was gap-filled and attributed using satellite imagery as a guide prior to rasterising. Most of these areas comprised a mixture of MVG 24 (inland water) and 25 (cleared), and in some case 99 (Unknown).
Each feature class was then rasterised to a 100m raster with extents to a multiple of 1000 m, to ensure alignment. State rasters were then merged into this 'Australia wide' raster dataset.
