The downloadable ZIP file contains a georeferenced TIF.  This data set is a mosaic of 24 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.<br /><div><br /></div><div>These data were contributed to <a href='https://insideidaho.org' rel='nofollow ugc' target='_blank'>INSIDE Idaho</a> at the <a href='https://www.lib.uidaho.edu' rel='nofollow ugc' target='_blank'>University of Idaho Library</a> in 2004.</div>
