Bushfire - Resource Deployment Optimising Tool

Esk Mapping and GIS developed an ESRI Add-In to Optimise Ground and Air Attack Resource Deployment to Bushfire Incidents, as part of the wider Bushfire Risk Assessment Model (BRAM).

    'FireSpread' Model

Working with the Tasmanian Parks and Wildlife Service (TPWS), Esk Mapping & GIS developed the 'Resource Deployment Tool' ESRI Add-In for ArcMap 10 using the Microsoft .NET Framework (C#). The tool gives an effective and immediate solution to the Duty Officer as to the optimum Ground or Air Attack resource that should be deployed to a fire incident anywhere in Tasmania. The tool forms part of the wider Bushfire Risk Assessment Model (BRAM) developed as a decision support tool for bushfire fighting planning and response within Tasmania. 

Deployment Optimiser 

Immediately the map coordinates for a new bushfire incident are known, the tool can rapidly determine from the state-wide pool of TPWS, Tas Fire Service (TFS), Forestry Tasmania (FT) and privately contracted tankers, rotary aircraft or fixed-wing aircraft stored in its database, which will arrive within effective range of the fire in the shortest amount of time. The tool has the ability to run and store multiple scenarios for each fire incident. For Ground Attack scenarios, the Add-In utilises the power of ESRI's Network Analyst to determine the optimum route across the Tasmanian transport network.

Esk Mapping and GIS also developed the Python 'FireSpread' model, run from within the Add-In, which maps the geographic extent of the Fire Boundary at the Estimated Time of Arrival (ETA) for the optimum Ground and Air Attack Resources. The 'FireSpread' model utilises the forecast Rate of Spread (ROS) raster model, as generated daily by the PWS Bushfire Operational Hazard Model  (BOHM), to propagate a simplified wavelet spread model based on a grid of nodes superimposed on the ROS data.

The system incorporates a database of all fire stations, field offices and bases, to which ground and air attack resources are allocated, the availability and location of which can be easily modified by the Duty Officer as fire crews and supporting organisations report in. The inputs and results of each deployment optimisation that are run are stored in text file format for audit trail purposes.
