You can download Exposure Analysis (EA) outputs for use outside of IFTDSS. This can be done from My Workspace by right clicking on the Exposure Analysis file to show the file options, then clicking Download.
Downloading
When the "File Download" window opens, by default the folder has the same Exposure Analysis name you selected when running an EA. If you prefer to change the name for use on your computer you can click on the name field and type a different name, this does not change the name in IFTDSS.
The individual files within the downloaded zip folder are prefixed with the original or modified <Exposure Analysis Name>. Once extracted, the folder includes:
| Output | File Type | Naming | Brief Description |
|---|---|---|---|
| Multiband GeoTIFF | .tif | <Exposure Analysis Name>.tif | EA outputs in raster format for use in ArcMap. See the Exposure Analysis GeoTIFF topic for more detail. |
| Table of HVRAs | .csv | <Exposure Analysis Name>.csv | A table listing the Primary HVRA Categories, the Sub-HVRA names, and the Sub-HVRA short names. |
| Symbology_ArcMap | folder containing .lyr files | <output type>.lyr | Symbology files for setting colors in ArcMap that match those used in IFTDSS. See the Symbology Layer topic for Landscape Burn Probability for more details. |
| Symbology_ArcPro | folder containing .lyrx files | <output type>.lyrx | Symbology files for setting colors in ArcGIS Pro that match those used in IFTDSS. See the Symbology Layer topic for Landscape Burn Probability for more details. |
The screenshot below shows an example of files in the downloaded zip folder for an Exposure Analysis output. In the image the <Exposure Analysis Name> was BFR Prod EA.
Layers (also known as bands) included in the GeoTIFF are listed in the table below.
| Band # | Output | Brief Description | Map Studio Units | Report Units | Download Units |
|---|---|---|---|---|---|
| 1 | 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 Burn Probability for more detail. | proportion | proportion | proportion |
| 2 | Conditional Flame Length A B | The mean flame length of all the fires that burn a given point on the landscape. See Conditional Flame Length for more detail. | feet | feet | feet |
| 3 | Integrated Hazard A B | The combination of Burn Probability and Conditional Flame Length ranging from lowest probability/lowest conditional flame lengths to highest probability/highest conditional flame lengths. See Integrated Hazard for more detail. | unitless | unitless | unitless |
| 4 | Sub-HVRA 1 | Rasterized version of Sub-HVRA, where the band name is <Primary HVRA Category>-<Sub-HVRA Short Name>. Where the Sub-HVRA is present the value is 1, where it is absent the values is NoData. See Exposure Analysis Technical Documentation for more detail. | unitless | unitless | unitless |
| n | 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.
