General GIS Data Elevation 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.

    Cartoogechaye 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. All data are in UTM Zone 17 NAD83 with units of meters. A 10 meter DEM is included for each watershed. These 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.

  Other Coweeta Watershed Land Cover 1942
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. Land cover was manually classified for each 25x25m cell (1/16th of a ha). Classifications were completed for each 10x10m cell simultaneously across all years to maximize temporal accuracy and consistency. Six land cover classes were used:

Code--Name (description)
1)--100% forest
2)--Transitional forest (those areas at least 25% forest cover that were abandoned or harvested and left to return to 100% forest)
3)--Agriculture
4)--Riparian/Shrubland
5)--Developed
6)--Open Water (mostly rivers and streams were open water was visible and ponds)
