Overview

Buildings is a digital dataset representing buildings across Australia. The Buildings dataset has relationships with the G-NAF, Cadastre, Property and Administrative Boundaries products produced by Geoscape Australia.

Data quality and potential capture timelines will vary across Australia based on the capture_method (Aerial or Satellite) and capture_resolution (e.g. 7cm, 50cm) of the record. Aerial capture includes enhanced attribution in comparison to Satellite capture.

Geoscape welcomes your feedback on the Buildings product. We also publish regular product development updates on our website ( www.geoscape.com.au ).

Change Notifications

Buildings - Primary Building Enhancement

Geoscape has implemented new logic to assign a primary building from multiple candidate buildings at single address sites for the September 2026 release. At these sites, it is assumed that there is one primary building/dwelling as this is usually the case. This logic change has resulted in the additional assignment of 956,703 'Yes' primary_building values and 1,428,464 'No' primary_building values where the primary_building values were previously null in the June 2026 release.

Issues

New Issues

Resolved Issues

Estimated Floors

A rounding error in the calculation for "estimated_floors" had the value being less then expected. This has been rectified and corrected for this release.

Unexpected changes to linkage identifiers

In the June 2026 release, a processing issue caused the building_cadastre_pid, building_property_pid, and date_created fields to change for approximately 3 million records in the building_cadastre and building_property tables. The issue has been resolved and no additional records are affected in the September 2026 release. For records impacted in June 2026, these values have remained unchanged unless a legitimate update to the underlying data has occurred.

Known Issues

8 MapINFO TAB Geometry issues

We have become aware of 8 geometries in the Buildings MapINFO TAB file format that contain self-intersections due to the way MapINFO TAB alters geometries on extract. We will look into resolving this in a future release.

Address_pool ‘No’ pool_flag assignment

We have become aware of ~5,000 cadastre that exist on the edge of two adjacent capture areas but do not have a large enough overlap to be related to either, meaning a null pool_flag is assigned to the cadastre and through it, the address. As these addresses were not assigned a ‘Yes’ or ‘No’ pool_flag, they are not included in the address_pool table. We have high confidence that there is no pool present on these cadastre as a pool was not captured in either capture area, and the capture areas usually have a high combined percentage overlap (usually ~100%) with the cadastre. We will look to assign these addresses with a ‘No’ pool_flag and include them in the address_pool table in a future release.

Future Considerations

This section outlines enhancements or changes under consideration, but not planned into a specific release. For further details on future initiatives, please contact Geoscape Support.

Annex A – Release Counts
