This is a data-set level implementation of the Federal Geographic Data Committee's Content Standards for Digital Geospatial Metadata. DOQ's serve a variety of purposes, from interim maps to field references for earth science investigations and analysis. The DOQ is useful as a layer of a geographic information system and as a tool for revision of digital line graphs and topographic maps. Information about county and individual DOQ records can be obtained from the EROS Data Center. See re-distribution NOTE Data available for distribution by USGS Eros Data Center.
