Content Description
Abstract:
The Digital Raster Graphic (DRG) is a raster image of a
scanned USGS topographic map including the collar information,
georeferenced to the UTM grid.
Purpose:
A DRG is useful as a source or background layer in a GIS,
as a means to perform quality assurance on other digital products,
and as a source for the collection and revision of DLG data. DRG's
can also be merged with other digital data, e.g. DEM's or DOQ's, to
produce a hybrid digital file.
