General GIS Data	Aerial Photography	Coweeta NE DOQQ Description - USGS 1:24000 Digital orthophoto quadrangle in the southern Appalachian Mountains (northeast area of Coweeta) (contributed by K.C. Love, 2011)

		Coweeta NW DOQQ Description - USGS 1:24000 Digital orthophoto quadrangle in the southern Appalachian Mountains (southeast area of Coweeta) (contributed by K.C. Love, 2011)

		Coweeta SE DOQQ Description - USGS 1:24000 Digital orthophoto quadrangle in the southern Appalachian Mountains (southeast area of Coweeta) (contributed by K.C. Love, 2011)

	Elevation	Coweeta Synoptic Sampling Program LIDAR DEM Description - This 6.67m digital elevation model was derived from NCDOT LIDAR survey obtained as base data for the Coweeta Synoptic Sampling Program (contributed by John Chamblee, 2011)

		Watauga Watershed 10m DEM Description - These data were collected to reconstruct spatially-explicit land use/land cover change trajectories that were temporally consistent and at very high accuracies. The data were developed for four watersheds in Macon County, NC: Cartoogechaye, Coweeta, Skeenah Creek Watershed and Watauga. Buildings (pts) and roads (lines) were digitized from historic maps and aerial photographs and aligned where necessary for temporal consistency. Land cover was simultaneously classified across all years for each 25x25m pixel (1/16 ha) in order to maximize temporal consistency. 10 meter DEM for each watershed were subset from USGS developed DEMS. These DEMS are useful as a mask for raster analyses and for derived additional data such as slope and aspect. (contributed by Ryan Kirk, 2011)
