Title: Shoreline Mapping Program of MITROFANIA ISLAND, AK, AK0403
Status: Completed
Creation Date: 2020
Abstract:

These data provide an accurate high-resolution shoreline compiled from imagery of MITROFANIA ISLAND, AK . This vector shoreline data is based on an office interpretation of imagery that may be suitable as a geographic information system (GIS) data layer. This metadata describes information for both the line and point shapefiles. The NGS attribution scheme 'Coastal Cartographic Object Attribute Source Table (C-COAST)' was developed to conform the attribution of various sources of shoreline data into one attribution catalog. C-COAST is not a recognized standard, but was influenced by the International Hydrographic Organization's S-57 Object-Attribute standard so the data would be more accurately translated into S-57. This resource is a member of https://www.fisheries.noaa.gov/inport/item/39808

Purpose:

The shoreline and associated data layers were originally intended to support NOAA Nautical Chart production. These datasets may be beneficial for performing change analysis for erosion and accretion studies, land use planning, determination of boundary extent, and other types of decision making.

Data Quality

Horizontal Positional Accuracy:

Compiled to meet 10 meters horizontal accuracy at 95% confidence level. This predicted accuracy

of compiled well-defined points is a deductive estimate based on

statistics of image rectification process

Completeness Measure:

All data are clipped to the neatline representing a surveyed project boundary. Line segments which did not close were snapped by the nodes to create consistently tied strings without node dangles.

Completeness Report:

The shoreline and associated data are a representation based on an office interpretation of imagery at the time of survey taken 199910. To maintain shoreline continuity, a line with 'Shoreline/Alongshore Feature Boundary' attribution was added to the 'Shoreline' class. This feature is an artificial line that separates double-lined alongshore features from the shoreline. The 'Shoreline/Alongshore Feature Boundary' indicates to the user that a man-made alongshore feature is coincident to the shoreline in the data file. The rectangular geographic boundary limits is for data management purposes and does not infer complete surveyed coverage.

Conceptual Consistency:

The attribute accuracy was verified on the softcopy workstation by overlaying the vectors over the imagery and by creating checkplots of the attributed linework. The attributes were translated into NGS's Coastal Cartographic Object Attribute Source Table (C-COAST) for data consistency. The C-COAST attributes were given symbology and visually inspected to verify attribute accuracy.

Process Steps

Process Step 1

CC ID: 916762
Description:

Softcopy compilation was from interpreted imagery based on standard digital photogrammetric procedures. All features were attributed during compilation. The exported shapefile attribution was translated to conform with the NGS 'Coastal Cartographic Object Attribute Source Table (C-COAST)' attribution scheme.
