Two vegetation maps (sold separately) - Natural Vegetation (1788) and Post-European Vegetation (1988) reconstruct Australia`s vegetation in the 1780s and the mid-1980s. Areas over 30,000 hectares are shown, plus small areas of significant vegetation such as rainforest. Attribute information includes: growth form of tallest and lower stratum, foliage cover of tallest stratum and dominant floristic types. Data was captured from 1:5 million source material. These maps are also available as free vector GIS data. Product Specifications Coverage: Australia Currency: Compiled mid-1980s Coordinates: Geographical Datum: AGD66 Projection: Simple Conic on two standard parallels 18S and 36S

Subtidal to intertidal deposits from Kaipara Harbour in Northland preserve a 23,000+ year incomplete sedimentary record of the transition from terrestrial to estuarine conditions in the Wairoa River arm of the harbour. Cores are used to reconstruct the depositional setting for this transition, which we interpret as a succession from dune and freshwater wetland to shallow estuarine environments. The fossil pollen record provides a proxy of Last Glacial Maximum and Late Glacial vegetation for the area. Stability of the palaeo-dune landscape during the postglacial marine transgression is interpreted on the basis of strong dominance of tall forest taxa (Dacrydium) in the pollen record and soil development in dune sands. Reworking of buried dune and wetland sediments has only reached to a depth of 1.5 m below the modern tidal flat. As such, the site provides a rare example of good preservation of Pleistocene deposits at the coast, where extensive reworking and loss of record are more typical.

Contains a medium scale vector representation of the topography of Australia. The data include the following themes: Hydrography - drainage networks including watercourses, lakes, wetlands, bores and offshore features; Infrastructure - constructed features to support road, rail and air transportation as well as built-up areas, localities and homesteads. Utilities, pipelines, fences and powerlines are also included; Relief - features depicting the terrain of the earth including 50 metre contours, spot heights, sand dunes, craters and cliffs; Vegetation - depicting forested areas, orchards, mangroves, pine plantations and rainforests; and Reserved Areas - areas reserved for special purposes including nature conservation reserves, aboriginal reserves, prohibited areas and water supply reserves.

One of the components of the FIRE-DST project is investigating fire modelling in the urban and peri-urban interface at the local neighbourhood scale. Each building in the interface will be examined to assess its vulnerability to the approach of a fire for each of ember attack, radiant heat and flame contact. The vulnerability will be dependant on a multitude of factors in the environment including the building construction, roof type, fences and other barriers. The vulnerability will then be used to calculate the expected impact of a fire on the urban area. To be able to model the fire movement and the affect on the built environment there has to be an accurate categorisation of the interface vegetation fuels. In this presentation we will focus on the creation of a 3D model of the neighbourhood scale vegetation and buildings. The neighbourhood scale environment will be created by including individual building information (like building age, wall construction type, roof type and occupancy) from the Geoscience Australia NEXIS database. There also has to be an accurate categorisation of the interface fuels and so specific details of other information such as individual trees, fences and forest will be obtained from high resolution LiDAR. LiDAR will also used to provide both the height and vertical profile of the vegetation in the urban interface. Other geographical information such as roads and a digital elevation model are also required. All this neighbourhood information is then processed to generate a 3D Model of the local environment.

Shows the vegetation of Australia in the mid-1980s. Areas over 30,000 hectares are shown, plus small areas of significant vegetation such as rainforests and croplands. Attribute information includes: growth form of tallest and lower stratum, foliage cover of tallest stratum and dominant floristic types. Data are captured from 1:5 million source material, suitable for GIS applications. The source map is also available for purchase.

This project commenced in November 2012 and is intended to provide satellite data and related scientific services to support the Murray-Darling Basin Authority's monitoring of how the condition of riparian vegetation responds to changing river run-off and wetland inundation levels. Under this project, Geoscience Australia started to build a satellite data processing infrastructure; named the 'datacube', as a proof of concept for expected on-going time series analysis applications including historical flood and bathymetry mapping. The work incorporates an automated processing chain for Landsat satellite images from Geoscience Australia's extensive archive, into customised high level intermediate products, including automated ortho-rectification, atmospheric correction, cloud-removal, and mosaicking, and finally into statistics on the spectral and derivative indices (that is, vegetation condition indices or various types) for the summer periods of December-March, each year for the period 2000-2013. These vegetation indices and associate statistics are then used, by the Murray-Darling Basin Authority and its collaborators, as inputs to a mathematical model of vegetation types and their respective conditions within the Murray-Darling Basin.

The Sustainable Management of Coastal Groundwater Resources Project was co-funded by the Raising National Water Standards Program, which supports the implementation of the National Water Initiative Program. The project was led by GHD Hassall, in consultation with Kempsey Shire Council, Geoscience Australia, NSW Department of Environment, Climate Change and Water, and Ecoseal Developments Pty. Ltd. The project aimed to improve the management of groundwater in coastal dune aquifers, undertaking a case study of the Hat Head National Park region on the Mid North Coast of New South Wales. Due to increasing pressures on groundwater resources from expanding urbanisation and tourism in this region, the sustainable management of the existing groundwater resources is of vital importance. There are many potential risks associated with extraction of groundwater resources including acidification of soils, seawater intrusion and increased salinity levels, and detrimental impacts on groundwater dependent ecosystems (GDEs). This final report documents all of the work undertaken by Geoscience Australia relating to Groundwater Dependent Ecosystems, or more specifically groundwater dependent terrestrial vegetation. Groundwater dependent ecosystems (GDEs) are naturally occurring ecosystems that require access to groundwater to meet all or some of their water requirements so as to maintain their communities of plants and animals, ecological processes and ecosystems services. Often the natural water regime of GDEs will comprise one or more of groundwater, surface water and soil moisture.
