Geoscape™ – 3D data on Australia’s built environment

Release 1.4 – National coverage – with 15.4 million buildings now available.

PSMA Geoscape captures extensive three-dimensional data about Australia’s built environment.  This initiative is based on satellite imagery that PSMA sources from Digital Globe.

Geoscape includes:

  • Building roof polygon (including number of vertices and roof area)
  • Maximum roof height (above ground)
  • Average eave height (above ground)
  • Elevation (above sea level)
  • Primary roof material classification
  • Solar panel and swimming pool indicators
  • Zone and residential indicator
  • Surface cover
  • Tree coverage and height
  • Image capture date
  • Linkages to PSMA G-NAF and CadLite

Why Callpoint Spatial for Geoscape:

  • We are PSMA’s first reseller to have licensed Geoscape. You gain access to the extensive experience we’ve built in helping customers across the telecoms, government, professional services, engineering, acoustics and tertiary/ health research sectors
  • Our value-added Geoscape Extra, plus a range of customisation options
  • One stop: we license the full PSMA dataset suite, which means that you can meet your complete PSMA dataset needs by sourcing from us
  • Our advisory capacity

 

Callpoint Spatial Geoscape Extra:

PSMA Geoscape is a rather complex dataset. The Buildings Theme alone has 28 attribution tables associated with the key Building Polygon geometry data.  To improve Geoscape’s functionality, joins need to be made from key attribution table columns back to the Building Polygon geometry data.  In other words, the raw PSMA Geoscape requires fair work to be put to use. The resulting processes then need to be repeated each quarterly update. Further, these processes may need to be revised should PSMA update the Geoscape data model.

To help our customers, Callpoint Spatial’s Geoscape Extra includes the results of these numerous table joins.  We perform these processes for each jurisdiction on a quarterly basis.

Callpoint Spatial Geoscape Extra can be delivered in formats including MySQL database backup, Microsoft SQL Server database backup, Shapefile/ Geodatabase and TAB.

 

Application ideas:

The resources on this page suggest potential applications across telco, professional services, health care, real estate and solar energy, to name a few. For further details including licensing please contact us.

Telecoms – fibre optic

For accurate fibre optic pricing and modelling, the Cadlite/G-NAF combination may not suffice. Being able to access building polygon data can be highly beneficial.  Geoscape provides building footprint data.

The green dots represent the coordinates of addresses, and are sourced from PSMA’s separate G-NAF dataset
The black outlines represent land parcel boundaries, sourced from PSMA’s separate CadLite dataset
The light blue street polyline layer is sourced from PSMA’s separate Transport & Topography dataset

Telecoms – wireless

 Geoscape’s building outline, elevation and other data can provide important input to your RF propagation/ wireless network coverage modelling.

Professional services 

When coupled with ABS data, Geoscape’s zoning and other attribution can support a range of geo-demographic modelling applications.

Health care research

Access to land cover data including tree coverage can be useful to GIS analysis in the health care research sector.

Tree Canopies and heights

Geoscape’s 2m Tree Cover data provides height attribution.  This can prove useful in applications from conservation to wireless telecoms.

Tree heights are depicted by depth of green shading.

Solar Panels

Data regarding buildings with installed solar panels can be useful to the renewable energy and nascent domestic power storage industries.  Being able to identify suitable buildings (roof pitch, area and likely minimal shading) can facilitate potential new opportunities.

The red outlines (PSMA Geoscape October 2018 edition) show building polygons whose rooftops have been assigned a solar panel indicator.

Swimming Pools

 Data regarding buildings that are deemed to have an associated swimming pool can prove useful across multiple sectors and applications.
