资源简介：
This Digital Raster Graphic (DRG) was created using
scanned U.S. Geological Survey 7.5-minute 1 to 24,000
scale maps georeferenced in Universal Transverse
Mercator (UTM) grid. DRGs can be acquired with or
without collar information for use in Geographic Information
System (GIS) environment. Collarless DRGs can be edge
matched creating a continuous collection of topographic
maps.
