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.
