After receiving the standard USGS-produced DRGs, the Land
Information and Computer Graphics Facility (LICGF) carried out two
basic processing steps:
a. The "collar" surrounding the map portion of each DRG and
containing ancillary information about the printed
map, such as
scale bars, legend and attribution, was re-classified
to a distinct
range of pixel values in the scanned image (values
20 through 32).
This enables ArcView users to optionally "turn off"
the DRG map
collar for display purposes.
b. DRGs were converted to the Wisconsin Transverse Mercator (WTM)
coordinate system, based on the North American
Datum of 1983
(NAD83).
