Rate of spread is the speed with which a fire moves in a horizontal direction across the landscape, usually expressed in chains per hour (ch/hr) or feet per minute (ft/min). For purposes of the Colorado WRA, this measurement represents the maximum rate of spread of the fire front. Rate of Spread is used in the calculation of Wildfire Threat in the Colorado WRA. Rate of spread is a fire behavior output, which is influenced by three environmental factors - fuels, weather, and topography. Weather is by far the most dynamic variable as it changes frequently. To account for this variability, four percentile weather categories were created from historical weather observations to represent low, moderate, high, and extreme weather days for each weather influence zone in Colorado. A weather influence zone is an area where, for analysis purposes, the weather on any given day is considered uniform. There are 11 weather influence zones in Colorado. This output represents the weighted average for all four weather percentiles. The Characteristic Rate of Spread map is derived at a 30-meter resolution. This scale of data was chosen to be consistent with the accuracy of the primary surface fuels dataset used in the assessment. While not appropriate for site specific analysis, it is appropriate for regional, county or local planning efforts.</DIV></DIV></DIV> Colorado State Forest Service, Colorado Wildfire Risk Assessment Project 2012 characteristic rate of spread rate of spread fire behavior Colorado Wildfire Risk Assessment CO-WRAP external a118dd2db33d6e2c2d57124229a58c9f Richard Homann Colorado State Forest Service 5060 Campus Delivery Fort Collins Colorado 80523-5060 US 970-491-8500 True Richard Homann Esri ArcGIS 13.6.3.59530 002 File Geodatabase Raster Dataset dataset EPSG 6.18.3(9.3.1.2) Pixel 4302 4923 30.000000 30.000000 8 1 Upper Left FALSE LZ77 1 pixel codes FGDBR TRUE row and column 30.000000 30.000000 VAT_CharacteristicRateofSpread Table 6 OBJECTID OBJECTID OID 4 0 0 Internal feature number.
