Land Use Land Cover (LULC) Data Frames
Description
Datasets containing information on the land use and land cover (LULC) characteristics calculated at all LAGOSNE spatial classifications (see ?scales) from the National Land Cover Dataset (NLCD).
Format
Data frames with all or a subset of the following variables. Number of observations is equal to the number of zones in each spatial scale (see Details below). Wildcard options include the 9 LAGOSNE spatial scales (* = buffer100m, buffer500m, iws, hu12, hu8, hu4, edu, county, state), year of measurement (** = 1992, 2001, 2006, 2011), and unit of measurement in hectares or percent of zone area (*** = ha, pct unless noted otherwise). Each variable is available at each scale, year, and unit unless otherwise noted.
*_nhdid (* = buffer100m, buffer500m, iws)
*_canopy2001_***: per pixel tree canopy percent measured 2001. Summary statistics include minimum, maximum, mean and standard deviation (*** = min, max, mean, std).
*_damdensity_***: dams in zone. Summary statistics include a point count, points per hectare, and points per square kilometer (*** = pointcount, pointsperha, pointspersqkm)
*_nlcd**_***_0: No data
*_nlcd**_***_11: Open water
*_nlcd1992_***_21: Residential, low intensity
*_nlcd**_***_21: Developed, open space. Note, this variable was not measured in 1992 (** = 2001, 2006, 2011)
*_nlcd1992_***_22: Residential, high intensity
*_nlcd**_***_22: Developed, low intensity. Note, this variable was not measured in 1992 (** = 2001, 2006, 2011)
*_nlcd1992_***_23: Commercial/industrial/transportation
*_nlcd**_***_23: Developed, medium intensity. Note, this variable was not measured in 1992 (** = 2001, 2006, 2011)
*_nlcd**_***_24: Developed, high Intensity. Note, this variable was not measured in 1992 (** = 2001, 2006, 2011)
*_nlcd**_***_31: Bare rock/sand/clay
*_nlcd1992_***_32: Quarries/strip mines/gravel pits measured in 1992

*_nlcd1992_***_51: Shrubland measured in 1992.
*_nlcd1992_***_52: Scrub/shrub. Note, this variable not measured in 1992 (** = 2001, 2006, 2011)
*_nlcd1992_***_61: Orchards/vineyards/other measured in 1992.
*_nlcd**_***_71: Grasslands/herbaceous
*_nlcd**_***_81: Pasture/hay

*_nlcd1992_***_83: Small grains measured in 1992.
*_nlcd1992_***_85: Urban/recreational grasses measured in 1992.
*_nlcd**_***_90: Woody wetlands. Note, this variable not calculated in 1992 (** = 2001, 2006, 2011). Equivalent code for 1992 = 91.
*_nlcd1992_***_91: Woody wetlands measured in 1992. Equivalent code for 2001, 2006 and 2011 = 90.
*_nlcd1992_***_92: Emergent herbaceous wetlands measured in 1992. Equivalent code for 2001, 2006, and 2011 = 95.
*_nlcd**_***_95: Emergent herbaceous wetlands. Note, this variable not calculated in 1992 (** = 2001, 2006, 2011). Equivalent code for 1992 = 92.
*_roaddensity_***: Roads within the zone, calculated as sum of the length in meters, or sum of the length in meters divided by area of zone in hectares (*** = sum_lengthm, density_mperha)
*_slope_***: The slope at each cell is the slope with respect to its immediate neighbors (10m scale). Cells in zone summarized as either the minimum, maximum, mean, or standard deviation (*** = min, max, mean, std)
*_tri_***: Terrain ruggedness index (TRI) at each cell is the absolute difference in meters between the elevation of the focal cell and its immediate neighbors (10m scale). Cells in zone summarized as either the minimum, maximum, mean, or standard deviation (*** = min, max, mean, std)
*_zoneid: unique zone identifier (* = iws, hu12, hu8, hu4, edu, county, state)
lagoslakeid: unique integer identifier for focal lake
lakeconnection: connectivity class of focal lake. Only in iws.lulc table.
borderiws: whether iws zone intersects Canadian border (1 = yes, NA = no). Only in iws.lulc table.
