JS Site Viewer combines publicly available NSW and Commonwealth datasets. This page attributes those sources and their licences. All data is used as indicative reference only — see our Terms and the disclaimer on every report.
Indicative only. Nothing on this site is a certified survey, valuation,
planning certificate or legal advice. Verify every figure with the relevant council, a registered surveyor,
a certifier and/or a planning professional before acting.

Some feeds carry provider-specific terms (e.g. OpenSky's non-commercial API limits) which we honour;
where a source cannot be cleared for commercial use it is removed rather than shipped (as we did with the
non-commercial EOX Sentinel-2 basemap).
