| # 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](https://github.com/milleleaf/sa-planning). Every feature and every field of each source is kept. |
|
|
| | Layer | Source | Holds | |
| |---|---|---| |
| | `zones` | [Planning and Design Code Zones](https://data.sa.gov.au/data/dataset/8321117d-2712-4912-9c47-a52ddb6b527f) | P&D Code zones, all of SA | |
| | `overlays` | [Planning and Design Code Overlays](https://data.sa.gov.au/data/dataset/ef82af6a-b57b-426b-949e-1ff97969fc1c) | Every P&D Code overlay in one layer (heritage, hazards, flooding, noise, height and more); filter on `name` | |
| | `land-use` | [Land Use Generalised (2025)](https://data.sa.gov.au/data/dataset/9712e707-1a7a-464e-a4c3-980f40770d48) | Generalised land use | |
| | `height-limits` | [Building Height Limits](https://data.sa.gov.au/data/dataset/4c4edb70-28fc-448f-a88f-29ba8f854b79) | Statutory maximum building heights (storeys, metres) | |
| | `climate-zones` | [Energy Efficiency (Climate) Zones](https://data.sa.gov.au/data/dataset/1ae7c6ac-1c07-46a7-be09-b060a53752d7) | NCC energy-efficiency climate zones | |
| | `energy-concession-areas` | [Energy Efficiency Concession Areas](https://data.sa.gov.au/data/dataset/131403e0-3f15-457d-a73f-a607b35f7e73) | Areas with energy-rating concessions | |
| | `bushfire-protection-areas` | [Bushfire Protection Areas](https://data.sa.gov.au/data/dataset/30e275dd-a6f3-4af5-8b8a-6f4919ff6fe7) | Bushfire risk areas used by the building rules | |
| | `earthquake-hazard-zones` | [Earthquake Hazard Zones](https://data.sa.gov.au/data/dataset/98259e9b-480f-401f-b715-f52d0c17cb72) | Building-code earthquake hazard factor zones | |
| | `corrosion-areas` | [Corrosion Environment Areas](https://data.sa.gov.au/data/dataset/00077ae8-57b2-40b7-b4b5-491872163d70) | 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](https://huggingface.co/buckets/milleleaf/sa-planning), 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](https://www.kaggle.com/datasets/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`). |
