Bushfire Mapping on the Web
Bushfires are a natural part of the Australian landscape. Many of our native flora and fauna have adapted to the specific fire regimes of the regions in which they live. If Australian communities are to do the same then it is important that we are able to accurately map and monitor fires on a near real-time basis. Such information allows emergency services to control bushfires, develop risk assessments and disaster relief plans.
Bushfires and grassfires are common throughout Australia. Grassfires are fast moving and smoulder for minutes while other fires can sweep across vast areas and continue burning for many weeks.
Sentinel is an internet-based national bushfire monitoring and mapping system run by Geoscience Australia to provide timely information to emergency service managers across Australia about 'hotspots' (areas of elevated thermal spectral response). The mapping system enables users to identify the locations of fire which create a potential risk to communities and property. The system is not isolated to emergency service agencies however and is used by climate change researchers, policy makers and the broader public.
The Sentinel system uses the Moderate Resolution Imaging Spectroradiometer (MODIS) and Advanced Very High Resolution Radiometer (AVHRR) sensors to detect areas producing high levels of infrared radiation accurately, and pinpoint their position to within 1.5km. The use of multiple systems allows Sentinel hotspots to be updated daily.
