Data sources & attribution

Lot boundaries, road-reserve parcels and aerial imagery are sourced from NSW Spatial Services (SIX Maps) © State of New South Wales.

Land zoning, floor space ratio, height of buildings, minimum lot size, heritage, bushfire prone land, flood planning and landslide risk are sourced from the NSW Planning Portal (ePlanning) © State of New South Wales and the Department of Planning, Housing and Infrastructure. Heritage information may also be cross-checked with the NSW Heritage database.

2m contour data is sourced from the NSW Elevation and Depth theme (NSW Spatial Portal).

Building footprint data from OpenStreetMap © OpenStreetMap contributors, licensed under the ODbL.

NCC Climate Zone data is sourced from the Australian Building Codes Board (ABCB). NatHERS Climate Zone data is sourced from the Nationwide House Energy Rating Scheme (NatHERS).

Planning, heritage and hazard layers do not imply endorsement by the NSW Government. Hazard layers (flood and landslide) are only published for some councils - a "Not mapped" result does not guarantee a property is unaffected.

Building outlines

Building outlines are sourced from OpenStreetMap, a community-maintained dataset. Coverage and accuracy vary across NSW. In Sydney metropolitan areas, outlines are generally well-mapped and closely match the aerial imagery. In regional and rural areas, outlines may be incomplete, outdated, or poorly aligned with actual structures on the ground. This is because volunteer mapping effort is concentrated in higher-density areas.

When in doubt, compare the building outline with the aerial imagery visible on the map. If the outline does not match, treat it as unreliable. Building outlines should not be used for setback measurements, site coverage calculations, or any design purpose without independent verification.
