Forest Carbon Diligence
About Forest Carbon Diligence
The Forest Carbon Diligence product is composed of a bundle of data resources: Canopy Height, Canopy Cover, and Aboveground Live Carbon at 30-meter spatial resolution. These data resources are produced annually over the entire landmass of the Earth (between 75° N and 60° S).
Discover samples of Forest Carbon Diligence, free to all active Planet users and Sentinel Hub users with a paid subscription: Sandbox Data for Forest Carbon Diligence.
Basic facts
Note: This chapter describes version 1.0 of the Forest Carbon Dligence product, which is currently supported by the Sentinel Hub Data Import API. For the newer version 1.1, which will be supported soon and is already available through the Planet Subscriptions API, please find the documentation here.
