        report:  (DQ_AbsoluteExternalPositionalAccuracy)
            nameOfMeasure:  Horizontal Positional Accuracy Report
            evaluationMethodDescription:  The horizontal accuracy of the grid is expressed as an estimated root mean square error (RMSE). The estimate of the RMSE is based on horizontal accuracy tests of the source data which are selected as equal to or less than the intended horizontal RMSE error of the grid. Horizontal positioning of the various source points were compared with each other to verify grid accuracy.
            result: (missing)
        report:  (DQ_AbsoluteExternalPositionalAccuracy)
            nameOfMeasure:  Vertical Positional Accuracy Report
            evaluationMethodDescription:  The vertical RMSE is used to determine vertical accuracy of the grid. It accounts for systematic and random errors. The accuracy of bathymetric soundings are within 2% of depth. The original topographic soundings are accurate within one-half the contour interval.
            result: (missing)
        report:  (DQ_CompletenessCommission)
            evaluationMethodDescription:  Errant data points were removed from the various sources before processing the grid. The final grid was visually and statistically inspected for completeness using ArcGIS.
            result: (unknown)
        report:  (DQ_ConceptualConsistency)
            measureDescription:  Each data set went through a stringent quality control procedure from their respective originators. The developed grid was compared with initial sources, other source control data, and corresponding data between datasets to verify accuracy.

                description:  Each raw data source was converted into ESRI ArcGIS formats. The resulting files were converted and adjusted to predetermined projection (geographic), horizontal datum (NAD27), and vertical datum (MHW). A polyline shapefile was created to represent the coastline. The coastline is a culmination of USGS hydrographic vectors, NOS high-resolution coastline, USACE data, and local knowledge of the area. A TIN (Triangulated Irregular Network) was created using bathymetric data point and coastline points. An 0.88-second grid was created from the tin. The data were assessed for quality and anomalies were removed. The grid was compared to its raw dataset. The 0.88-second grid was clipped to requested coordinates. A 0.88-arcsecond grid was created using USGS DEMs and UAF DEMs. The data were assessed for quality by comparing with raw datasets and control data. The topographic and bathymetric grids were merged into a single grid. The final grid was analyzed for blunders, systematic errors, and logical consistency.
