* Metric Name: Canopy Veg Height  

* Tier: 1  

* Data Vintage: 06/2020  

* Unit Of Measure: Continuous meters, where each pixel value represents the average height above ground for vegetation within that pixel  

* Represent element and pillar: No  

* Type and distribution of data: Zero-inflated, right-skewed distribution representing continuous values. Raw data values range from 0 to 80.  

* Translation: Where is canopy vegetation high?  

* Translation method and outcome: Raw data values translated to range from +1 to -1 representing more favorable to less favorable conditions, respectively. **** The proposition of more favorable is based on the objective of canopy vegetation being higher (positive linear slope). More favorable (translated to +1) and less favorable (translated to -1) are based on climate and vegetation regions (Table 6).

* Metric Definition and Relevance: This layer represents distance between the ground and the top of the canopy. Canopy height is a proxy for aboveground biomass and the amount of foliage that may be consumed in a canopy fire. Since LANDFIRE doesn’t support a NoData value, all NoData pixels in canopy fuel metrics were set to 0 in the Landscape files. (e.g., canopy cover was set to 0 in all NoData locations). Topographic data and surface fuel model remain unaltered.
