2.  Data Quality Information

   2.1  Attribute Accuracy

  2.1.1 Attribute Accuracy Report:  This map was created by linking 7
    USGS 1:100,000 scale DLG files and eliminating all boundary lines
    (DLG files:ze1.hyf05,ze1.hyf06,ze3.hyf01,ze3.hyf02,ze3.hyf05,
    rh4.hyf04 and rh4.hyf08). Minimal edgematching was done when necessary 
    to correct for inconsistancies visible after the DLG sections were 
    joined. Some attribute values were added and some were shifted to 
    different attribute columns, to enable better use in ArcView without
    loss of origional USGS data values. See BIGCODE.HTM 2.4.3 for a complete 
    explanation of USGS attribute accuracy. All attribute information 
    contained in this map was deleted, along with interior land features
    to create an outline of the county's shoreline and northern boundary. 

    The northern county boundary line was digitized at UVA from 1:24,000 USGS
    quadrangle maps, 7.5 minute series (topographic). the sections used
    were Jamesville, Exmore, Nassawadox and Quinby Inlet, VA.
    All data above this line was deleted from the coverage.
   
   2.3 Completeness Report: All area within Northampton County limits

   2.4  Positional Accuracy: See BIGCODE.HTM 2.4.2 for a complete
        explanation of USGS positional accuracy.

   2.5.2 Process Step

         2.5.2.1  Process Description: Information obtained from
	 USGS DLGs online Server(www.usgs.gov). The DLG sections used for
         this coverage were listed at
         http://edcftp.cr.usgs.gov/pub/data/DLG/100K
         The DLGs were converted using DLGARC. JOINITEM was used to link
         DLG major and minor codes as attributes in the ARC coverages.
         APPEND was used to unite the seven coverages, then boundary
         boxes were removed.  Minimal EDGEMATCHing was done to correct
         inconsistancies between sections (automatically, using
         EDGEMATCH and manually, in ARCEDIT).

         2.5.2.2  Source Used Citation Abbreviation: 
         The USGS DLGs used, in full or in part, to complete the
         Northampton County section were: ze1.rdf05, ze1.rdf06, ze3.rdf01,
         ze3.rdf02, ze3.rdf05, rh4.rdf04 and rh4.rdf08.

      2.5.2  Process Step

         2.5.2.1 Process Description: Existing attributes were used to 
         isolate all arcs which represented shoreline. All other arcs were
         deleted. This included internal land features such as streams,
         and tidal flats which were idedtified as being on the ocean side 
         of the shoreline.  A paper copy of the 1:100,000-scale map was
         used by the processor to visually verify this outline. The northern
         county line was coded as "no_data" and preserved along with the 
         shoreline to create the outline.
