The Division of Coastal Management provides financial support to coastal communities who wish to provide public access to waterfront areas. This GIS data set provides point locations of such access sites in North Carolina. Attributes that can be taken from this layer include: the municipality or county responsible for the site (sponsor), the general size of the parking lot, the type of waterfront (urban, ocean, estuarine), the date the data were collected and the DCM contract number of the site.
This data was created to assist governmental agencies and others in making resource management decisions through use of a Geographic Information System (GIS).

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.
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.
Only located beach access sites funded by DCM grants. Other access sites exist, and some of these are marked with DCM access site signage.
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.
Beach Access Sites location GIS export file with attributes.
The supplied Arc/Info export file was imported and is managed as part of the North Carolina Corporate Geographic Database.
Beach Access Sites were collected on a Trimble GPS Datalogger. The data were downloaded to a UNIX Sun SPARC Station using Arc/Info GIS software. The data were then converted into an Arc/Info coverage, and projected to the Stateplane Coordinate System. Only 3-D points were accepted (4 satellites) while standing at the seaward end of the crossover to collect the point. An Arc Macro Language (AML) program was used to input attribute information. The completed coverage was then exported and sent to CGIA for inclusion in the NC Corporate Geographic Database.
