Digital Raster Graphic (DRG) Mosaic of Idaho at 1:100,000-scale

Description

The downloadable ZIP file contains a georeferenced TIF.  This data set is a mosaic of 69 individual DRGs georeferenced to the IDTM83 grid. The original Digital Raster Graphic (DRG) is a raster image of a scanned USGS topographic map including the collar information, georeferenced to the UTM grid.   DRGs are useful as a source or background layer in a GIS and as a means to perform quality assurance on other digital products.

These data were contributed to INSIDE Idaho at the University of Idaho Library in 2004.
