<scope-and-purpose>A digital raster graphic (DRG) is a scanned image of 
a U.S. Geological Survey (USGS) standard series topographic map, 
including all map collar information. This particular dataset is 
composed of scans of the most current edition (as of date of scanning) 
of 1:24,000-scale topographic maps of California; the sheets were 
scanned by the Teale Data Center. The image inside the map neatline is 
georeferenced to the surface of the Earth and fitted to the Universal 
Transverse Mercator projection. The horizontal positional accuracy and 
datum of the DRG matches the accuracy and datum of the source map. The 
map is scanned at a min resolution of 250 dots per inch.</scope-and-purpose>
