In this document, you'll learn the following: First, we'll discuss what biophysical settings (BpS) and the associated LANDFIRE BpS models are. Second, you'll learn how you can use the BpS models and associated descriptions. After that, we'll go over some background information on how they were created. We'll then illustrate how to obtain the BpS descriptions from the LANDFIRE website, and you'll download an example BpS model description. And finally, we'll examine the major elements of the model descriptions and briefly look at the ancillary files included with the descriptions.
