These data represent the bare ground cover.

Fundamentally, the vegetation cover model is an observation-based (or empirical) model. This means that the model “learns” the relationships between satellite imagery and field data. Once relationships are learned, the model can then predict percent cover of five vegetation functional types available in the dataset:
Annual forb and grass
Perennial forb and grass
Shrub
Tree
Bare ground
What types of satellite imagery and field data are we talking about? Essentially, the RAP uses: 1) satellite imagery from the Landsat program and 2) field vegetation data from the Natural Resources Conservation Service’s Natural Resources Inventory (NRI), Bureau of Land Management’s Assessment, Inventory, and Monitoring (AIM), and National Park Service Northern Colorado Plateau Network (NCPN) programs.
Dataset was used as a model input for the Washington Columbia Plateau Least-Conflict Solar Project.
