National Buildings and Solar Refresh in Rural Areas

The June 2026 release includes a national refresh of rural areas across both the National Buildings and National Solar products, advancing Geoscape’s approach to maintaining currency, consistency and completeness across non-urban Australia. This change has resulted in a minor version change for each of these products.

Building on the National Buildings 4.0 foundation introduced in March, this update leverages newly sourced high-resolution satellite imagery (30 cm) to recapture and validate building features across rural and regional areas. This improved imagery enables more accurate identification of structures, supporting the addition of previously missing buildings and the refinement of existing features. The June 2026 update focussed on refreshing locations known to have buildings, with further updates planned later in the year to identify new construction locations not currently covered in the Buildings dataset.

Satellite update highlights

• ~824,000 newly detected buildings added

• 71% of satellite buildings are captured from imagery dated 2025 onwards, improving building currency across rural Australia

As part of this refinement, there is a net decrease in the total number of rural building features. Improved capture and classification processes have enabled more precise filtering of features, removing objects that do not meet the definition of a building within the National Buildings product, such as water tanks, silos and netted agricultural areas. This results in a more consistent and reliable representation of the built environment.

While the update introduces a large number of newly captured buildings, it also consolidates and removes superseded features.

Building footprint refinement

• ~19.14 million buildings in the current release

• ~19.50 million buildings in the previous release

• Net reduction of ~360,000 buildings, reflecting improved accuracy and alignment to current building definitions

Note: Any features removed across these areas in the June 2026 release can be provided on request.

The updated capture has also improved attribute completeness and usability within the National Buildings dataset. In particular, an increased number of features now include a Primary Building flag, supporting clearer identification of primary dwellings relative to secondary structures.

Solar attribute uplift

A key enhancement in this release is the improvement in solar panel attribute completeness:

• Solar assessment coverage increased to 99% of all buildings (up from ~40%)

• Significant increase in usable solar coverage across rural areas

These enhancements directly support improvements to the National Solar product. With more accurate and consistent building footprints in rural areas, solar panel detection and representation has been extended across these regions. This enables the provision of solar attributes, including panel area and estimated power generation, for buildings across rural Australia, supporting a more complete national view of the renewable energy landscape.

This release also establishes a more scalable approach to maintaining both Buildings and Solar coverage into the future. Geoscape is targeting at least annual review and update cycles using the latest available imagery, with ongoing releases continuing to prioritise areas where building and solar data coverage can be further improved.

Satellite update coverage

Geographic coverage of buildings captured through the June 2026 satellite update, demonstrating broad national coverage.

Approximately 62,000 buildings partially within our update areas have been retained from prior capture for completeness and therefore have not been assessed for solar panels. These locations will be included in our future update programs to recapture these buildings and their attributes from the latest imagery.

Solar Building - Rural Update Roof Attribute Population

For the June 2026 release, rural capture areas were assessed only for the roof_colour attribute for inclusion in the building_roof insights pack table related to the Buildings product. As a result, approximately 3,000,000 new records have been added to the building_roof table with a populated roof_colour value. The remaining attributes - roof_shape, primary_roof_material, roof_slope, and tree_overhang - are null, as they were not assessed during this capture. In addition, there are approximately 1,500,000 buildings within rural update areas where both roof_colour and primary_roof_material are populated, while roof_shape, roof_slope, and tree_overhang remain null. In these cases, only roof_colour was newly captured. However, primary_roof_material was already available from previous data collection and has been retained.

These changes also affect the roof attribute population in the Solar product solar_building table.

Buildings captured as part of the new rural dataset can be identified using the following attributes: - capture_resolution = ‘30cm’ - capture_method = ‘Satellite’

Building_address enhancements at complex sites

In the March 2026 release, processing changes meant that sites with multiple addresses and many large buildings were not linked, as we did not have confidence in these relationships. For example, at a site with 150 centrally located addresses and 160 dwelling-sized buildings on a single parcel, it is not possible to reliably determine which address corresponds to which building. Excluding these links also avoids a significant increase in record volume. In this scenario alone, linking all combinations would generate 24,000 building–address relationships. Including similar cases across the dataset would expand the building_address table to over 100 million records.

For the June 2026 release, we have reassessed some of these sites and have provided a link between the buildings and a single address (usually a primary address or equivalent). This logic excludes the many other addresses from linking to buildings at these sites. This allows for some representation of the site in building_address, but limits the number of introduced records. As we know that these sites contain multiple addresses, we assign all buildings that meet our size and planning zone considerations at these sites as primary_building = ‘Yes’ in building_address and primary_building_flag = ‘Yes’ in the buildings table.

Buildings at these sites will be assigned with an address_count of 1 in the buildings table as they have only been linked to a single address in the building_address table. In reality, there are more addresses present at these sites. If you require a list of affected buildings, please contact Geoscape Support.

This has affected the Solar product which also utilises these new building to address relationships.

Versioning Update (Starting June 2026)

Beginning June 2026, all data products will transition to a standardised versioning format: MAJOR-MINOR-EXTRACT (e.g., 004-000-001). This approach provides a clear and consistent structure, making it easier for users to identify product versions and understand update levels at a glance. The change is intended to improve transparency, reduce ambiguity, and support more efficient integration and usage of our data products.

Implementation of New Zip File Naming and Packaging Standards (Starting August 2026)

As part of ongoing improvements to product consistency and packaging standards, updates to zip file naming conventions and internal packaging structure will be implemented, starting in August 2026.

Zip File Naming

Two standard naming patterns will be used, depending on whether an extract contains spatial information:

• Spatial Tables:

{PRODUCT-NAME}_{RELEASE YYYYMM}_{REGION}_{CRS}_{FORMAT}_{VERSION MAJOR-MINOR-EXTRACT}.zip

• Aspatial (Insights) Tables:

{PRODUCT-NAME}_{RELEASE YYYYMM}_{REGION}_NODATUM_{FORMAT}_{VERSION MAJOR-MINOR-EXTRACT}.zip

Packaging Structure

All zip files will follow a simplified, flat directory layout:

• No nested folders

• The primary data file will be located at the top level of the zip.

Note: The product package will no longer include supporting content.txt files.

These changes ensure consistent packaging across all products, reduce complexity, and support improved automation and user experience.

Known Issues

Solar polygons cut off at the edge of capture areas

Where a solar polygon is captured that crosses the edge of a capture area, the portion of the solar array that is outside will not be included in the product. This occurs in a small number of instances and will result in smaller than real-world solar_area and daily_estimated_power values.

Incorrect capture of solar polygons

Solar hot water heating, swimming pool heating and other rooftop features such as air-conditioning units can incorrectly be captured as solar polygons. These features are removed from the data where possible as they do not represent photovoltaic solar. Geoscape intends to continue to improve our processes to reduce these occurrences over time.

Solar type accuracy for low-resolution capture

Where a solar polygon is captured using imagery with resolution greater than or equal to 10cm, there is a reduction in the correctness of the solar_type classification. This often causes monocrystalline panels to be assigned with a ‘Thin-film’ solar_type value as individual panels cannot be differentiated in the imagery. Daily estimated power outputs for these records will be lower than the real-world value.

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.

Z-values

Geoscape is considering including z-values for the solar table that would provide heights for each vertex of a solar polygon. There is potential for this information to be used to derive other attributes, such as the aspect of the solar panel.

Aspect

Geoscape is considering including an ‘aspect’ attribute that would describe the direction that the solar panel is facing. This attribute could potentially be used to improve estimates of the power generated by the solar array.

Improvements to Daily Estimated Power

Geoscape intends to further improve the daily_estimated_power attribute. For this improvement we would potentially assess the impact of the:

• resolution of the imagery used to capture the solar polygon

• aspect of the solar polygon

• roof_shape of the building related to the solar polygon

• surrounding heights of buildings, trees and other features such as mountains that could potentially shade the solar array and reduce the power output

Adjustments to this estimate will be made from the results of this assessment.

Solar polygons that are not related to a building

Geoscape intends to include solar panel polygons that are not rooftop solar. These panels often relate to solar farms and are currently excluded from Solar as they do not relate to a building. The intention would be to link these solar panels to an address.
