system filename: cen70 file size = 2.9 mb Revisions and updates to this layer include: 2.) filename: cen701298 The December 1998 update to this layer consisted of projecting the data from NAD27 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. 1.) filename: cen70794 July 1994 - (also archived as nc.cen70, filename was change July 31, 1996, no data changed). Due to discrepancies in population totals, the DEHNR-State Center for Health Statistics, Environmental Statistics and GIS Section reviewed the population totals and corrected inaccuracies in July 1994. Due to funding constraints, the previous file had only been thoroughly quality-controlled within the Albemarle-Pamlico Estuarine Study Area.
