Delineation of Australia's domestic and international maritime limits and boundaries. These boundaries include a variety of jurisdictional, economic, regulatory and legal boundaries. <b>Value:</b> Used by national governments, businesses, organisations in determining boundaries for zones governed/managed by different regulatory structures/requirements. <b>Scope:</b> A national dataset at resolution relevant for presentation of regional spatial data such as digital maps or regional decision making.

A `weighted geometric median' approach has been used to estimate the median surface reflectance of the barest state (i.e., least vegetation) observed through Landsat-8 Operational Land Image (OLI) observations from 2013 to September 2018 to generate a six-band Landsat-8 Barest Earth pixel composite mosaic over the Australian continent. The bands include BLUE (0.452 - 0.512), GREEN (0.533 - 0.590), RED, (0.636 - 0.673) NIR (0.851 - 0.879), SWIR1 (1.566 - 1.651) and SWIR2 (2.107 - 2.294) wavelength regions. The weighted median approach is robust to outliers (such as cloud, shadows, saturation, corrupted pixels) and also maintains the relationship between all the spectral wavelengths in the spectra observed through time. The product reduces the influence of vegetation and allows for more direct mapping of soil and rock mineralogy. Reference: Dale Roberts, John Wilford, and Omar Ghattas (2018). Revealing the Australian Continent at its Barest, submitted. <b>Value: </b>Has broad application in mapping surface geochemistry and mineralogy of exposed soil and bedrock. Has applications in geological mapping and natural resource management including mapping of soil characteristics. <b>Scope: </b>Two enhanced bare earth products have been generated reflecting different Landsat satellites and acquisition periods. The first only uses Landsat 8 observations from 2013 to 2018. The second incorporates the full 30+ year archive combining Landsat 5, 7, and 8 from 1986 to 2018.

<div>The 1:250,000 AUSTopo Map Series Index underpins the new 1:250,000 AUSTopo Australian Digital Topographic Map Series (published from 2023). The index drives the online 1:250,000 topographic index dashboard and accompanying web service. Within this index, each of the 516 map sheets that comprehensively cover Australia is presented as an individual tile. The dataset contains value-add attributes, including map title, tile number, the latitude and longitude of the maps sheets, and year/s published. The index also features direct download links to the maps. </div><div><br></div><div>This index exists alongside the previous 1:250,000 map series index, which served as the framework for map editions published between 1995 to 2012. </div><div><br></div><div>Available in ESRI Shapefile and GDB.</div>
