Salo Forest Observatory Layers in Lens


Salo Sciences, Inc. has developed the California Forest Observatory, which maps wildfire drivers across the state on an annual basis. This data is derived from airborne lidar and satellite data used to train machine learning models. Data is provided from 2016 to 2020 at 10-meter spatial resolution, and a subset of data is provided at 3-meter spatial resolution using Planet data.

Getting Salo Forest Observatory Layers into Lens

We’re thrilled to be able to bring this data into Lens for customers interested in forest monitoring in California, and eventually other geographies as well. If your organization is interested in viewing these layers for your California properties in Lens, reach out to us at to learn more. 

About Salo’s Forest Observatory Data Layers

Canopy Cover - the horizontal cover fraction occupied by tree canopies, measured as a percentage. An area with 0% canopy cover would have no trees at all, and 90+% would be a dense forest. 

Canopy Height - The distance between the ground and the top of the canopy. Canopy height is an indicator of aboveground biomass and the amount of foliage that may be consumed in a crown fire. It is measured in meters

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. Measured in meters.

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. Measured in kilograms per cubic metre.

Canopy Layer Count - The number of distinct vertical canopy layers. Vertical layer count is a proxy for leaf area index, and maps canopy complexity. Forests with multiple layers tend to be more diverse and resilient.  

Ladder Fuel Density - The amount of surface / understory fuels. These ladder fuels can carry a fire up towards the tree canopy. It is measured as a percentage where more ladder fuel means a higher risk that fires will spread up to the forest canopy. 

Surface Fuels - Combined layer which takes into account vegetation fuel type, size class, depth, moisture content and heat content. Determines fire behavior patterns like flame length and spread rate. Darker orange indicates a faster spread rate in the event of a fire, since more fuel is available to burn.

Wildfire Hazard - This layer incorporates information about burn probability or likelihood and the intensity of a fire if one occurs. The Wildfire Hazard layer is designed to inform planning and management efforts to mitigate the risk of wildfire events. 

Dry Vegetation - Percentage of dry vegetation on the property, which impacts wildfire risk.

Green Vegetation - Percentage of green, or healthy vegetation on a property. 

Burn Severity - The intensity of a fire that has occurred in this region during the year selected. Note that this layer will not have data for years when no fire events occurred.
