The Territory-wide wildfire risk metrics in FireRisk reflect the current and forecasted wildfire risk across the entire project area. The results are shown through gridded layers representing risk in terms of fire size potential, number of buildings impacted, and population impacted (same impacts as asset risk). For each of the outputs, the user will be able to choose whether to display the result in the output’s native units (e.g. acres for fire-size potential) or their percentile value to see the spatial and temporal distribution of the risk across the project area.
Territory Wide Ignition Locations
The impact analysis for a single fire spread prediction is calculated for a regular grid of ignition points across the project area (1000 m grid spacing). This provides a continuous coverage across the territory. For each daily 100-hour weather forecast, the risk outputs are calculated for each ignition point every 3 hours, consistent with asset risk.
A fire spread prediction is calculated for each ignition point, for each 3 hour time slice. A standard 8 hour duration for each spread prediction (simulation) is used and outputs calculated for the duration.
