Their names, descriptions and categorization are as follows:\n\nHousing\nThis raster dataset contains seventeen housing layers which are all named in the format \"bhc1940,\" where \u2018bhc\u2019 is Built Housing Capacity and year represents the decades from 1940 through 2100. The layers depict the location and density of private land housing unit classes, as described below. The classifications were produced using the SERGoM v3 model (see Theobald, D. 2005. Landscape patterns of exurban growth in the USA from 1980 to 2020. http://www.ecologyandsociety.org/vol10/iss1/art32). These data are based on existing US Census datasets and growth projections. \n\nSERGoM_bhc_metrics:\n\nValue CLASSNAME\n0 Private undeveloped\n1 < 1.5 units / square km\n2 1.5 - 3 units / square km\n3 4 - 6 units / square km\n4 7 - 12 units / square km\n5 13 - 24 units / square km\n6 25 - 49 units / square km\n7 50 - 145 units / square km\n8 146 - 494 units / square km\n9 495 - 1,234 units / square km\n10 1,235 - 2,470 units / square km\n11 > 2,470 units / square km\n12 Commercial/industrial\n\n\nLand Cover\nLand cover and impervious surface data comes from version 2 of the circa 2001 National Land Cover Dataset (NLCD), the circa 2006 NLCD, and the NLCD 2001/2006 Land Cover Change product, which was acquired from the Multi-Resolution Land Characteristics Consortium. The names and descriptions of the five land cover raster layers are as follows:\n\n- NLCD_2001v2. This raster layer depicts 16 land cover classes using data from version 2 of the circa 2001 National Land Cover Dataset. \n\n- NLCD_2006. This raster layer depicts 16 land cover classes using data from the circa 2006 National Landcover Database. \n\n- LandCover_2001. This raster layer depicts 16 land cover classes using data from the circa 2001 National Land Cover Dataset. \n\nLand cover classes for NLCD_2001, NLCD_2006 and LandCover_2001 are shown below. \n\nValue Land Cover\n11 Open Water\n12 Perennial Snow/Ice\n21 Developed, Open Space\n22 Developed, Low Intensity\n23 Developed, Medium Intensity\n24 Developed, High Intensity\n31 Barren Land\n41 Deciduous Forest\n42 Evergreen Forest\n43 Mixed Forest\n52 Shrub/Scrub\n71 Herbaceous\n81 Hay/Pasture\n82 Cultivated Crops\n90 Woody Wetlands\n95 Emergent Herbaceous Wetlands\n\n- ImperviousSurfaces_2001. This raster layer represents impervious surfaces using data from the circa 2001 National Land Cover Dataset.\n\n- ImperviousSurfaces_2006. This raster layer represents impervious surfaces using data from the circa 2006 National Landcover Database. \n\n- LandCoverChange_2001_2006. This raster layer represents land cover change from 2001 to 2006 using data from the NLCD 2001/2006 Land Cover Change product, which was acquired from the Multi-Resolution Land Characteristics Consortium.\n\n\nWildlife\n- Grizzly_Connectivity. This raster layer represents grizzly habitat connectivity in the GYA. For more information, please consult the corresponding reference citations from the report.\n\n\nAgriculture\n- GYA_Agriculture is a CSV file containing tabular county-level data from the 2002 and 2007 U.S. Department of Agriculture (USDA) Census of Agriculture.
