Derived data product DEA Hotspots
Last updated:19 August 2024
Spot areas of high temperature
Digital Earth Australia (DEA) Hotspots is a national bushfire monitoring system that uses satellite sensors to detect areas producing high levels of infrared radiation — called Hotspots — to allow users to identify potential fire locations with a possible threat to communities and property.
Hotspot colour shows how recently it was last observed by a passing satellite (red being most recent). Hotspot size shows how confident the algorithm is in correctly identifying a hotspot (large meaning high confidence).
Updated with new information every 10 minutes, DEA Hotspots can be viewed online, downloaded, or imported as a web service (WMS and WFS), allowing other platforms to draw on Hotspot information without having to store datasets locally.
Learn about how hotspot data is produced, and what it is used for.
