Charlottesville, VA 22903 USA.
1.13 Native Data Set Environment: ARC/INFO 6.1 running under SunOS
4.1 on a SUN SPARC station 1.
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.
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.

USGS DLGs
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.

readily interchangable between systems.) Another version was
converted to UTM, NAD83 using PROJECT for use on a UNIX system
and EXPORTed (compression FULL).
