system filename: basdcm file size = 0.15 mb Revisions and updates to this layer include: 3.) filename: basdcm1298 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. 2.)filename: basdcm598. Update included the addition of 3 beach access sites to the datalayer, and the addition of 2 items to the polygon attribute table, X-coord and Y-coord. 1.)filename: basdcm796 This is the first version of the data. The 796 in the filename stands for the July 8, 1996 version.

Data sources used in this process:
Data sources used in this process:
Attribute information was input onsite from observations made by field personnel and backed by information previously gathered and stored in the project files. An AML program was used to check for consistency.
Reviewed differential correction results. Only 0/0/0/0 corrections accepted (meaning all locations were corrected for SA and all data were acceptable). Ground positional accuracy is 2-5 meters. Data were collected using a Trimble Pro-Lite GPS receiver, accepting no less that 180 uncorrected locations per site. Locations are accepted at one second intervals from the satellites. The locations were differentially corrected using data from the closest base station on PFINDER software. The corrected points were then GENERATED into an Arc/INFO point coverage.
Only located beach access sites funded by DCM grants. Other access sites exist, and some of these are marked with DCM access site signage.
The data was built for points, using ARC/INFO's "build" command, to ensure topological consistency. There have been no edits since the last build or clean was performed.
Are there legal restrictions on access or use of the data?
