South Australia planning and land layers

Statewide planning and land layers published by the Department for Housing and Urban Development on Data.SA, as GeoParquet and vector tiles, checked weekly and rebuilt when a source changes by milleleaf/sa-planning. Every feature and every field of each source is kept.

Layer	Source	Holds
zones	Planning and Design Code Zones	P&D Code zones, all of SA
overlays	Planning and Design Code Overlays	Every P&D Code overlay in one layer (heritage, hazards, flooding, noise, height and more); filter on name
land-use	Land Use Generalised (2025)	Generalised land use
height-limits	Building Height Limits	Statutory maximum building heights (storeys, metres)
climate-zones	Energy Efficiency (Climate) Zones	NCC energy-efficiency climate zones
energy-concession-areas	Energy Efficiency Concession Areas	Areas with energy-rating concessions
bushfire-protection-areas	Bushfire Protection Areas	Bushfire risk areas used by the building rules
earthquake-hazard-zones	Earthquake Hazard Zones	Building-code earthquake hazard factor zones
corrosion-areas	Corrosion Environment Areas	Building-code corrosion environments

Per layer:

• <layer>.parquet (in this dataset): GeoParquet, every feature, every field as published, geometry in geom.
• <layer>.pmtiles (on the bucket, read by browsers): vector tiles, one layer named after the file, zooms 4 to 14, every field plus fid (the feature's row number in the Parquet file, from 0). Zoom 14 holds every feature at full detail: no feature or tile size limit, no tiny-polygon reduction, no simplification. Zooms 4 to 13 may leave out features in dense areas and simplify shapes, so those tiles stay small. A polygon too thin to survive the zoom-14 grid (a sliver a few centimetres wide) is also given as a point on its surface, with tiny_polygon_point: true; index.json counts them per layer.

index.json holds the counts, each source's URL, Last-Modified and size, and the CRS. manifest.json lists every file's sha256. Geometry is the GDA2020 (EPSG:7844) file of each source, which web maps can use as WGS 84 (they differ by less than 2 m).

GDA94 copies (Kaggle only). Each source zip also holds the same features in GDA94 (EPSG:4283). They are not on Hugging Face; they are in the Kaggle mirror, helenkwok/sa-planning, folder gda94/: each zip's <stem>_GDA94.geojson and <stem>_GDA94_metadata.html, copied out byte for byte (no reprojection, no field changes). manifest.json lists their sha256 too, and index.json counts their features (<layer>_gda94).
