A key lesson learnt from the fire management community is that the earlier an appropriate fire response can be mounted the better; resulting in significant community benefits. However, it can be hard to monitor a country as large as Australia and to detect fires, particularly in vast and remote areas where fire ground intelligence is not easily available. The Sentinel monitoring system provides an important and consistent overview for management of fires across the country. The system was developed in the mid-2000’s through a collaborative effort between Geoscience Australia, AGO and CSIRO Land and Water. The system monitors hotspots nationally and provides timely hotspots information to its end-users. Sentinel has been a valuable input into the tools used by government and private agencies managing fires in Australia. A number of land management and emergency response agencies have taken data feeds from the Sentinel system to embed into their routine fire management operations enhancing their situational awareness programs to assist staff, managers and the community. Hotspot data when merged with other spatial information provide a strategic picture to land managers; which allows them to understand the implications of a particular fire as well as to target resources. GA has completed a re-development of Sentinel, from the infrastructure that supports the system through to the spatial technology and user-interface. These changes will allow GA to more easily integrate data from different platforms and sources as well as provide additional products through the Sentinel interface. The new Sentinel was developed in consultation with stakeholders to ensure a close alignment between end-users needs and the services provided. The main areas improved in the new Sentinel were: Implementation of a robust and maintainable ‘backend’ system, enabling quick and easy ingestion of new sources of hotspot data and fire related products; Improved user interface for the visualisation and download of current and archived hotspots data; Separate access for emergency management users to ensure reliable access to hotspots data during a disaster event; Improved interoperability, through reconsideration of the attributes used to describe a hotspot, anticipating the need for a standard approach to this problem
