General GIS Data Other Coweeta Synoptic Sampling Program TIGER Water Features
Description - The TIGER/Line Shapefiles are an extract of selected geographic and cartographic information from the Census MAF/TIGER database. The Census MAF/TIGER database represents a seamless national file with no overlaps or gaps between parts. However, each TIGER/Line Shapefile is designed to stand alone as an independent data set or the shapefiles can be combined to cover the whole nation.

    Coweeta Synoptic Sampling Program Previous Study Watersheds
Description - The previous watershed study areas were included in this data set for comparison purposes. This data contains watershed delineations compiled from previous Coweeta studies.

    Coweeta Synoptic Sampling Program Final Watersheds
Description - The watershed boundary was intended to give the scientists a better idea of where the water in the synoptic sampling area was flowing. This data set was created through the watershed delineation process using the hydrological tools in ESRI's ArcMap 9.2, the DEM of the study area, and the synoptic field points collected by the scientists.

    Coweeta Synoptic Sampling Program Final Roads
Description - The road data was intended to help better visualize the amount of usage and traffic in the synoptic sampling study area. The road data was obtained from the Macon County GIS and has been clipped to only include the road data of the synoptic sampling watersheds.
Note: The road data for the synoptic sampling watersheds outside of Macon County is not included.

    Coweeta Synoptic Sampling Program Final Pour Points
Description - The pour points are the field points that have been corrected to make sure that they are located on an area of highest flow accumulation within a certain range. These points are the final points used for the watershed delineation process. They are the field points adjusted to make sure all points were on a pixel of high flow accumulation.

    Coweeta Synoptic Sampling NHD Flowline GUID Routes
Description - This stream set was intended for comparison of the synoptic flow accumulation model and for better visualization of the water flow in the synoptic area. This data was derived from the North Carolina Stream Mapping Program website at http://ncstreams.org. The data was then clipped to only include the hydrography of the synoptic sampling watersheds.

    Skeenah Watershed Buildings 2006
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. Separate Shapefiles are available for buildings for several years. Buildings for 1906 were digitized from original USGS topographic maps. Buildings for 1929 were digitized from the original Soil Survey. All other years were digitized from aerial photographs. A point is included for each building with the exception of farmyards, where one building was placed in the approximate center of multiple buildings (house, barn, shed, garage, etc). Building locations are snapped between years so that newly constructed or recently removed buildings can be detected for each year. There are no attributes in this data set.
