Resource Metadata

  • Title: Buildings
  • Identifier:
  • Abstract: Buildings is a national digital dataset representing buildings for each State and Territory in Australia. The dataset is comprised of four layers which represent the outlines of building objects, related building characteristics and linkages to related foundational data themes
  • Purpose: The purpose of Buildings is to spatially represent building-related features for use by industry and government in geographic information systems, visualisations, engineering modelling, and for the derivation of analytics.

  • Access, Use, Security:
    • Legal Constraints: license
    • Security Constraints: N/A
    • Use Limitations: The buildings dataset is a representation of building objects and related characteristics. Remotely sensed inputs including imagery sources and elevation models have absolute and relative positional accuracy limitations and so precise navigation with respect to represented objects may require additional qualification.
    • Releasability: The dataset should only be distributed in accordance with the licence under which it has been accessed.

      • Statement:

      The buildings theme (buildings layer) consists of digital representations of the roof outline of a building. Buildings have been digitised from remotely sensed imagery using a combination of automated and manual processes to identify, extract and orthogonalise objects resembling a building structure greater than 9m2. The process also determines building attributes including roof materials, the presence of solar panels and the presence of swimming pools. Image quality factors including currency, capture geometry, and 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. Data quality and potential capture timelines will vary across Australia based on three categories. Each category has been developed based on several factors defined by the population distribution (categorised based on population size), industrial/commercial activities, the probability of natural events (e.g. flooding) and the image source. Urban (satellite source) – areas with a population greater than 200, or with significant industrial/commercial activity in a visual assessment, digitised from satellite imagery Urban (aerial source) – areas with a population greater than 200, or with significant industrial/commercial activity in a visual assessment, digitised from aerial imagery. Rural – all other areas. Linkages from the Buildings theme to other Geoscape data themes (specifically G-NAF, Cadastre, Property, Localities, ABS ASGS, Geoscape Planning) are created through internal production processes. Building change management including process which describe how adds, retires and updates are applied to the dataset are described in the associated product guide.
