Description:
Abstract:
Linear hydrographic features, including rivers,
streams, and artificial flow paths through water
bodies. Data were captured from USGS 7.5 minute
mylar seperates containing the "blue-layer" from
the U.S. Geological Survey's 1:24000-scale
quadrangle maps. Individual quadrangles were
combined and edgematched using Arc/Info GIS
software, and then clipped into individual county
tiles using boundary data from the Georgia
Department of Transportation's 1:31360-scale
County General Highway Maps.
Purpose:
This data was compiled for use as a cartographic
layer in the Georgia Department of
Transportation's County General Highway Maps.

Process Step:
Process Description:
1. Mylar separates were scanned using an
Intergraph Eagle Scanner. 2. Scanned images were
vectorized and features taged 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.
