Quantitative Wildfire Risk Assessment (QWRA) GeoTIFFs from IFTDSS
The GeoTIFF for Quantitative Wildfire Risk Assessments (QWRA)s in IFTDSS contain the bands outlined in the table below:
| Band # | Band Name | Brief Description | Units in Map Studio | Units - GeoTIFF | Units - IFTDSS (Report) |
|---|---|---|---|---|---|
| 1 | Conditional Weighted NVC A | The sum-product of value change (to one or more resources or assets) over a range of flame lengths. See the Conditional Weighted NVC topic for more detail. | unitless | unitless | unitless |
| 2 | Expected Weighted NVC A | Burn Probability times Conditional Weighted NVC. See the Expected Weighted NVC topic for more detail. | unitless | unitless | unitless |
| 3 | Conditional Weighted NVC Classified | Categorical version of the Conditional Weighted NVC output to enable mapping in a GIS to match Map Studio. | categorical | categorical | categorical |
| 4 | Expected Weighted NVC Classified | Categorical version of the Expected Weighted NVC output to enable mapping in a GIS to match Map Studio. | categorical | categorical | categorical |
| 5 | Burn Probability A, B | The likelihood that a fire will burn a given point on the landscape (expressed as a value between 0 and 1). See the Burn Probability topic for more detail. | proportion | proportion | proportion |
| 6 | Proportion of Flame Lengths 0-2 ft A, B | The probability of fire burning with a flame length between >0 and 2 ft (expressed as a value between 0 and 1). See the Proportion of Flame Lengths topic for more detail. | proportion | proportion | proportion |
| 7 | Proportion of Flame Lengths 2-4 ft A, B | The probability of fire burning with a flame length between >2 and 4 ft (expressed as a value between 0 and 1). See the Proportion of Flame Lengths topic for more detail. | proportion | proportion | proportion |
| 8 | Proportion of Flame Lengths 4-6 ft A, B | The probability of fire burning with a flame length between >4 and 6 ft (expressed as a value between 0 and 1). See the Proportion of Flame Lengths topic for more detail. | proportion | proportion | proportion |
| 9 | Proportion of Flame Lengths 6-8 ft A, B | The probability of fire burning with a flame length between >6 and 8 ft (expressed as a value between 0 and 1). See the Proportion of Flame Lengths topic for more detail. | proportion | proportion | proportion |
| 10 | Proportion of Flame Lengths 8-12 ft A, B | The probability of fire burning with a flame length between >8 and 12 ft (expressed as a value between 0 and 1). See the Proportion of Flame Lengths topic for more detail. | proportion | proportion | proportion |
| 11 | Proportion of Flame Lengths >12 ft A, B | The probability of fire burning with a flame length 12 ft (expressed as a value between 0 and 1). See the Proportion of Flame Lengths topic for more detail. | proportion | proportion | proportion |
| 12 | Sub-HVRA 1 | The rasterized version of the presence of a Sub-HVRA at the same resolution of the Landscape Burn Probability outputs. See the Exposure Analysis Technical Documentation for more detail. | unitless | unitless | unitless |
| 13 | Sub-HVRA n... | Each subsequent Sub-HVRA you use in the analysis will have its own band, there can be up to 100 Sub-HVRAs total within a GeoTIFF. | unitless | unitless | unitless |
A Non-burnable pixels are indicated with a value of -1.
B Burnable but not burned pixels are indicated with a value of 0.
