Metadata must conform to the FGDC Metadata Standard. The actual data can reside on your own server, or can be distributed in some other way. DRGs are scanned images of USGS topographic sheets whereas DLGs are comprised of vector-based land-surface data layers. Through our web server you can download all data (including metadata), determine information on data production and availability, and link to other relevant sites.
