Revisions and updates to this layer include:
7.) filename: gdc0803 Layer updated August, 2003. 29939 points.
6.) filename: gdc1299 Layer updated December, 1999. Geodetic control
points added and attribute z-value added. 28549 points. Data is in
83, state plane, meters.
5.) filename: gdc1298 The December 1998 update to this layer consisted
of projecting the data from NAD83 datum, State Plane projection, units
of measure feet TO: NAD83 DATUM, State Plane PROJECTION, UNITS OF MEASURE
METERS. This was done to comply with the NC Geographic Information
Coordinating Council's "Statement of Direction for North Carolina
Corporate Geographic Database Horizontal Reference, Datum and Unit of
Measure". This reprojecting was done in various ways depending on the
data type and content. Vector data was projected using the 'project'
command in ESRI's Arc software and topology was cleaned and built based
on coverage needs. Raster data was projected using ESRI's Grid module
and various steps as applicable.
