On-Demand Spread Prediction Outputs (FireSim)
The following table presents a summary of the risk outputs derived for the on-demand fire spread predictions derived using the FireSim desktop and mobile applications. All outputs are provided as exportable GIS data and also summarized in a report for each prediction.
On-Demand Fire Spread Prediction Output Data (FireSim) | ||
Dataset | Format/ Resolution | Description |
Time of Arrival | Raster 30 m | Fire spread prediction depicted as a raster fire perimeter representing fire time of arrival for each cell. |
Fire Perimeter | Hourly Polygons / Shapefile | Fire spread prediction depicted as a hourly polygons. Can be exported to shapefile and XLS table. |
Fire Behavior | Raster 30 m | A series of charts and raster output map layers depicting conventional fire behavior outputs Rate of Spread, Flame Length, Fireline Intensity, Crown Fire Potential. |
Buildings Impacted | Total Number | Total number of buildings impacted during the duration of the prediction. Each building impacted will include time of impact, and time since ignition. This includes both summary and spatial location. |
Population Impacted | Total Number | Total number of population impacted by hour for the duration of the prediction. This includes both summary and spatial location. |
Acres Burned | Number of Acres | Summary of possible acres burned by hour for the duration of the prediction. This data is numeric only. |
Time of Arrival | KMZ | Ability to export the TOA raster data as a Google Earth KMZ file. |
Crown Fire Type | Raster 30 m | Torching (1), Conditional (2), Crowning (3) |
Fire Paths | Raster 30 m | Minimum travel time depiction of fire paths |
Wind Barbs | 2 km | Wind speed in barbs, long lines are 10 mph, short lines are 5 mph. |
