These data are derived from shoreline maps that were produced by the NOAA National Ocean Service including its predecessor agencies. Shoreline spatial data are considered a crucial element in land use planning, determination of boundary extents, performing change analysis for erosion and accretion studies, and other types of decision making.

The different codes depict shoreline, piers, dikes, jetties, breakwaters, and groins. A light table review of the checkplots would reveal any inaccurate coding. Mistakes would be identified and corrected until accurate checkplots were produced. The feature codes (f-codes) are identified as follows: Shoreline (1); Dike or levee (25); Jetty, breakwater, or groin (27); Pier, ramp, or dock (30); User added arc (-9999); Graticule (-9998); State Boundary (-9997); State Water (-9996) LOGICAL CONSISTENCY REPORT: Linework was vectorized to the neatline of the shoreline map. All data crossing the neatline was clipped to the neatline. All arcs were snapped by the nodes to create consistently tied strings without node dangles. COMPLETENESS REPORT: These shoreline data adequately represented the shoreline at the time of the survey. HORIZONTAL POSITIONAL ACCURACY REPORT: The horizontal positional accuracy for the digital data was tested by producing checkplots of the vectorized data and overlaying it with a plot of the rasterized T-Sheet on a light table. Linework which appeared to be greater than a pen width off of the T-Sheet was considered in error, and revisions were made until new checkplots revealed an accurate depiction of the T-Sheet. PROCESS DESCRIPTION: During the vectorization process, all adjoining shoreline maps in the project are displayed on a computer screen and the shoreline is traced and coded appropriately. Maps within a project generally adjoin and, therefore, there is significant agreement of linework across the borders of the shoreline maps. This results in fewer errors related to the edge-matching process. Polygon labels and attributes are assigned to features containing area so that users may shade the data to determine land and water. All lines are coded with the feature code (f-code) value, a feature name (f-name), the shoreline map number (t/tp-sheet#), the scale of the shoreline map, the survey date, and the date the spatial data were captured. After the edgematching process is complete, the state boundary of Maine was added, as was a one-degree buffer of the shoreline on the seaward side. This allowed for polygons to be created and attributed with the appropriate feature name (land/water). A 15-minute graticule was then overlayed onto the spatial data so that faster draw speeds of the data could be achieved. Lastly, the data were projected into the North American Datum (NAD) of 1983.
