Australian physiographic units

Submitted by on Wed, 27/09/2023 - 09:05

A list of physiographic units in Australia that provide a consistent framework for mapping soils and landforms at national and regional scales, compiled at a continental scale. The list was defined by Pain et al. (2011;* and built on the work of Jennings and Mabbutt (1986). It recognises a subdivision of the Australian onshore continent into three physiographic divisions, 23 physiographic provinces and 220 physiographic regions.

Western Australian mineral fields and districts

Submitted by on Thu, 21/09/2023 - 17:07

The State of Western Australia is divided into various Mineral Fields that represent administrative land subdivisions under which mining is administered in the State according to Section 16 of the Mining Act 1978. Some mineral fields are further subdivided into Districts. Mineral field and district boundaries can be changed by proclamation under the Mining Act 1978 — the listing provided is current as of June 2023. Each mineral field or district is characterized by a two-digit prefix code used for map representations and tenement indexing.

Western Australian coordinate reference systems

Submitted by on Thu, 21/09/2023 - 17:01

The coordinate reference systems (geographic and projected) used and referred to within Western Australia. It includes historical and current reference systems, Universal Transverse Mercator (UTM) zones, and, where applicable, notations based on the EPSG registry ( Some concepts are included to account for legacy data/maps with limited information.

Physiographic unit types

Submitted by on Thu, 21/09/2023 - 16:56

Characterization of the type of physiographic units used by the Geological Survey of Western Australia for mapping regolith and landforms in the State. A physiographic units is defined as 'A named geomorphological entity with internal coherence in its landform characteristics and landform evolutionary history. At the lowest levels, physiographic units reflect the underlying geology and have similar groupings of regolith materials that are related to the landform types, their evolution, and the underlying bedrock.' Physiographic unit types are based on the classification of Pain et al.

GSWA collection facilities

Names and physical locations of metropolitan and regional offices of the Department of Mines, Industry Regulation and Safety (DMIRS). The list includes venues with or without public access or information facilities, and highlights the location of Western Australia core libraries and offices of the Geological Survey, as well as Mine Inspectorate and Mining Registrar offices. 

Northern Territory Vegetation Site Database

Submitted by javiersan18 on Fri, 23/06/2023 - 10:02

The Vegetation Sites Database (VSD) is a vegetation and land information system for managing systematically collected site based data and point source records (i.e. threatened species). It is used to store information on the floristics and structure of site based surveys as well as both fine and broader scale environmental attributes. VSD accommodates data requirements of DEPWS and outside agencies (including environmental consultants).

Three Parks Savanna Fire-effects Plot Network

Submitted by javiersan18 on Fri, 23/06/2023 - 10:00

This data package comprises fire severity scores from Kakadu in 2014. A total of 220 permanent monitoring plots (40 m x  20 m) were established across three parks (Kakadu, Litchfield and Nitmiluk) in 1994-1995 to monitor biotic change. Of these, 132 plots are located in Kakadu. These sample a variety of landform and vegetation type/habitat conditions. A substantial proportion of plots were positioned deliberately at sites likely to reveal environmental dynamics, especially at ecotones and in patches of fire-sensitive vegetation. For example stands of Callitris, sandstone heaths.

National Roads

Submitted by joseph.abhayaratna on Wed, 21/06/2023 - 07:09

ESRI File Geodatabase detailing Geoscape Australia's National Roads dataset, consisting of roads, street_locality_line and street_locality_alias tables. The roads table provides a linear vector representation of road features across Australia that delivers an optimised and aggregated view of road geometry and attribution. It identifies and describes transport routes that enable vehicular, pedestrian and bicycle transportation, as well as ferry routes that allow for transport across water.
