Gap Analysis Project (GAP) habitat maps are predictions of the spatial distribution of suitable environmental and land cover conditions within the United States for individual species. Mapped areas represent places where the environment is suitable for the species to occur (i.e. suitable to support one or more life history requirements for breeding, resting, or foraging), while areas not included in the map are those predicted to be unsuitable for the species. While the actual distributions of many species are likely to be habitat limited, suitable habitat will not always be occupied because of population dynamics and species interactions. Furthermore, these maps correspond to midscale characterizations of landscapes,...

The Biogeographic Characterization Branch (BCB) has conducted a number of activities over the last several years that have resulted in databases of named, significant spatial features that are important as a foundation for other databases and in analytical processes. We've discovered that all of these activities involve some of the same type of work in quality controls and data prep and result in a simple, common schema for the fundamental data attributes. In an effort to bring all of this work together and get maximum benefit for our systems as a whole, we are establishing this foundational ScienceBase collection to house the information. We use "Spatial Feature" for this collection because each of the items...
