Description: UPPTM_200910 is a 90-m spatial resolution raster dataset that differentiates five types of protection: 1) private (unprotected); 2) private protected (with known conservation easement or other legal protection mechanism); 3) public protected (e.g., state, federal); 4) Tribal lands; and 5) military (bases, etc.).

Description: ESRI Streetmap 2003 was gridded at 30 m resolution to match the domain alignment of the NLCD2001 dataset. An inverse mask was made from the areas that were not streets and this was masked with the n-index from the NLCD2001. A regiongroup was run on this mask. The region group of the roadless areas was then reselected for only those areas greater than 5000 acres and recoded to PEA_RDLS5K --
Description: Those classes used were beaches, military bases, Native American reservations, parks (National, state , county, local), national parks and monuments. Most of the data was originally from usgs national atlas . HSIP access/use constraints was either none or graphics for official use. The data used only included boundaries and was combined to one mask layer (graphic) where no identifying features of individual items were portrayed.

Description: This data represents approximately 290 species (polygon and lines) that are Fish and Wildlife Service critical habitat layers These data identify, in general, the areas where final critical habitat exist for species listed as endangered or threatened. --
Description: The NLCD2001 data was recoded into 6 separate habitat/landscape classes (similar to the habitat types coded from the NLCD92 data use in the Southeastern Ecological Framework Project, Carr, etal 2002). A focal variety was calculated (hab_divmsk27) for a 27x27 window within the cat12ter grid. The final pea_div mask was generated from the grid hab_divmsk27 where the total variety was 5 or 6 within the 27x27 window.
