1.11 Data Set Credit: Data from NOAA/NOS - CERC Cooperative
Shoreline Movement Study, Cape Henlopen, DE - Cape Charles,
VA. 1980. Digitization and projection by John Porter, Dept. of
Environmental Sciences, University of Virginia,
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: Unknown
2.3 Completeness Report: Only the areas around Cobb Island were
digitized.
2.4 Positional Accuracy
2.4.1 Horizontal Positional Accuracy: 40.0
2.4.1.1 Horizontal Positional Accuracy Report: Estimated.
Digitization was <10 m however the underlying field
survey is unlikely to be that accurate.

2.5.2 Process Step
2.5.2.1 Process Description: Data was digitized into
ARC/INFO coverage cobbchng3. It was then transformed
using an affine transformation to latitude and
longitude (NAD27) and projected to the UTM system
using zone 18 and spheroid Clark 1866 to the NAD27
datum. Arcs were labeled with the relevant year. For
polygon coverages, label points were also labeled by
year.
