Abstract and purpose for the dataset


Geoscape is a suite of digital datasets which represent buildings, surface cover, trees, and has links to other PSMA products: G-NAF addresses, Cadastre and Property, Suburb/Locality and State/Territory. Data quality and potential capture timelines will vary across Australia based on three categories, each category has been developed based on a number of factors including the probability of the occurrence of a natural events (e.g. flooding), population distribution and industrial/commercial activities.

The Geoscape Dataset is comprised of three themes and one of the Themes has Layers as listed:

  • Buildings Theme
  • Surface Cover Theme (2 Metres and 30 Metres Layers)
  • Trees Theme

The purpose of the Geoscape national dataset is to spatially represent building and related features for the use by industry and government in digital applications / systems.

Lineage Statement

The digital representation of the building footprint features has been created via classified remotely sensed sources using automated techniques from high quality, ortho-rectified, base imagery. The base imagery used is selected from the available image catalogue. Image quality factors including currency, capture geometry, applicable weather conditions influence the specific image which can be utilised for further processing. A suitable high quality Digital Surface Model is constructed to assist with feature extraction. Each type of feature extracted follows a distinct (but related) processing stream.

Trees have been identified by their spectral signature using remotely sensed information and are also represented as raster cells within the surface cover dataset. Areas classified as Trees have been integrated with Digital Surface Model (DSM) and Digital Elevation Model (DEM) Information to extract a height value for every cell.

Although all efforts to provide an accurate height for all tree pixels have been undertaken, due to proximity to other features, resolution and anomalies within the Digital Surface Model (DSM) and/or the Digital Elevation Model (DEM) heights for a small portion of pixels are higher than the real world feature they represent.

Surface cover features are contiguous pixel representations of basic surfaces as identified and classified via automatic feature extraction routines over satellite imagery. This theme contains 2 variations; one a high resolution (2m) dataset representing surface cover within urban areas, the other a national resolution (30m) dataset representing surface coverage nationally.
