Description:
Abstract:
This dataset contains polygonal hydrographic
features including lakes, ponds, reservoirs,
swamps, and islands. Original data were captured
from Mylar separates containing the "blue-layer"
from the U.S. Geographic Survey's 1:24000-scale
quadrangle maps. Individual quadrangles were
combined and edgematched using Arc/Info GIS
software and then clipped into individual county
titles using boundary data from the Georgia
Department of Transportation's 1:31680-scale
County General Highway Maps.
Purpose:
This data was compiled for use as a cartographic
layer in the Georgia Department of
Transportation's General Highway Maps.

This was the primary source of the hydrologic
data.
Process Step:
Process Description:
1. Mylar separates were scanned using an
Intergraph Eagle scanner. 2. Scanned images were
vectorized and features tagged using Genasys
Genarave raster-to-vector conversion software. 3.
After DXF translation, vectors were loaded into
Workstation Arc/Info v6.1 coverages and manually
edited. 4. Individual quadrangle based coverages
were edgematched and appended together to form a
statewide coverage. 5. Coverages were plotted
to scale and overlayed on the source mylar and the
corresponding paper map for QA/QC.
