South Australia fire layers

Statewide fire layers published on Data.SA by the Department for Environment and Water and the SA Country Fire Service, as the GeoJSON files exactly as published plus two sets of vector tiles, checked weekly and rebuilt when a source changes by AlreadyOpen/sa-fire. Every feature and every field of each source is kept.

Layer	Source	Holds
`fire-history`	Bushfires and Prescribed Burns History (Department for Environment and Water)	Every mapped bushfire and prescribed burn on record (`INCIDENTTY`, `FIREDATE`, `FIREYEAR`, `HECTARES`)
`last-fire`	Last Bushfire and Prescribed Burn Boundaries (Department for Environment and Water)	The most recent fire at each place: the time since fire
`bushfire-management-areas`	Bushfire Management Areas (SA Country Fire Service)	The nine bushfire management areas
`emergency-location-markers`	Emergency Location Markers (Department for Environment and Water)	Numbered markers on trails and parks to tell emergency services where you are

Per layer:

*_GDA2020.geojson and *_GDA94.geojson (in this dataset; the GDA2020 file also on the bucket): the source's GeoJSON files, byte for byte, with their original names. GDA2020 is EPSG:7844, which web maps can use as WGS 84 (they differ by under 2 m); GDA94 is EPSG:4283.
<layer>.pmtiles (bucket, read by browsers), lossless: zooms 4 to 14, every field plus fid (the feature's position in the GDA2020 file, from 0). No feature or tile size limit, no tiny-polygon reduction and no point thinning (-r1) at any zoom; shapes are simplified below zoom 14. Zoom 14 holds every feature at full detail (the bake fails otherwise); a polygon too thin to survive the zoom-14 grid is also given as a point on its surface, with tiny_polygon_point: true.
<layer>-thinned.pmtiles (bucket), thinned: tippecanoe's defaults plus --drop-densest-as-needed, zooms 4 to 14. Features are left out where tiles get dense, so lower zooms show fewer of them. index.json counts what each zoom keeps.

index.json holds the counts (features in each GeoJSON; features at zoom 4 and 14 of each tile set), each source's URL, Last-Modified, ETag and size. manifest.json lists every file's sha256. Built with tippecanoe 2.79.0.
