Vegetation datasets

Canopy Cover

The horizontal area covered by tree canopies. Maps community type & fire regime, as well as habitat for tree-dwelling species.

Canopy Height

The distance between the ground and the top of the canopy. Canopy height is a good proxy for aboveground biomass.

Canopy Base Height

The distance between the ground and the lowest branches in the canopy. Predicts whether a surface fire transitions to a canopy fire.

Canopy Bulk Density

The mass of available fuel that burns in a canopy fire—typically the leaves and small branches— divided by the volume of the crown.

Surface Fuel Model

A model describing vegetation fuel type, size class, depth, moisture content and heat content. Determines fire behavior patterns like flame length and spread rate.

Ladder Fuel Density

The amount of brush and/or understory fuels. Maps where low-lying surface fires are most likely transition to canopy fires.

Green Vegetation Abundance

The amount of green, leafy vegetation. This includes all photosynthetic tissues.

Dry Vegetation Abundance

The amount of dry or dead vegetation, including dead grass, timber slash, dry brush, and leaf litter.

Vertical Layer Count

The number of distinct vertical canopy layers. Vertical layer count is a proxy for leaf area index, and maps canopy complexity.

Wildfire datasets

Burn Severity

A metric of the amount of vegetation consumed in a fire, as well as the heat at which it burned.

Active Hot Spots

Active wildfire hotspots measured by VIIRS, a satellite that measures thermal anomalies twice daily.

Daily Weather

Wind speed, wind direction, temperature, and humidity. Determines the rate of fire spread, especially in grass or shrub fires.
