SA Emergency Data: Sources and Coverage

South Australia has the most feeds of any state (7). Three agencies publish via ArcGIS REST through SAFECOM: CFS (Country Fire Service), MFS (Metropolitan Fire Service), and SES. Additionally, four pager feeds from urgmsg.net provide dispatch-level data with exact addresses and units dispatched.

Agencies: CFS (bushfires), MFS (metro fire), SES (floods, storms, rescues), plus CFS-PAGER, SES-PAGER, SAAS-PAGER, BOMBER-PAGER

Timestamps (critical): MFS and SES ArcGIS feeds return epoch milliseconds in Adelaide local time (ACST UTC+9:30 or ACDT UTC+10:30), NOT UTC. If you treat them as UTC, your timestamps will be 9.5 to 10.5 hours in the future. You must subtract the timezone offset before converting.

DST: Adelaide observes daylight saving. The offset changes between +9:30 (winter) and +10:30 (summer) on the first Sunday of April and October.

Geometry: ArcGIS feeds use a different JSON structure than GeoJSON. Requires conversion. CFS JSON feed uses "lat,lng" strings that need parsing.

Pager feeds: These are unofficial dispatch intercepts providing exact street addresses, unit callsigns, and incident details not available in the official feeds. Extremely valuable for granular data.
