        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:  The final grid was visually inspected for completeness using ArcView. The grid was compared with other sources through spatial analysis techniques. The grid was contoured to detect anomalies, which were corrected.
            result: (unknown)
        report:  (DQ_ConceptualConsistency)
            measureDescription:  Each data set went through a stringent quality control process from their respective originators. NOAA hydrographic surveys, and NOAA charts meet IHO Order 1 standards. USGS vector and dem data is based on USGS Level 2 standards. The developed grid was compared with initial data and other sources to verify accuracy.

        lineage:  (LI_Lineage)
            processStep:  (LE_ProcessStep)
                description:  Each raw data source was converted into ESRI Arc-compatible formats. The resulting files were converted and adjusted to predetermined projection (geographic), horizontal datum (NAD27), and vertical datum (MHW) using the ArcInfo PROJECT command and ArcView Spatial Analyst MAP CALCULATOR algorithm. An ArcView polyline shapefile was created to represent the coastline. The coastline is based on USGS hydrographic vectors. The USGS coastline was compared to high-resolution NGS vector shoreline; no discernible difference was found between the two datasets. Bathymetric contours and data points were digitized from raster charts and images. Each dataset was analyzed for quality. Anomalies were removed; approximately 30 points were removed from NOS hydrographic survey datasets. Overlapping contours and points were assessed for matching. Bathymetric data was prioritized by quality and date. Recent surveys superseded older data. A TIN (Triangulated Irregular Network) was created using bathymetric data and coastline vectors using ArcView 3D Spatial Analyst. A 0.88-arcsecond grid was created. The grid was contoured at 1-, and 5-meter contours to compare with the original datasets. Problematics areas were redone by adding additional contours in areas of low point density. The bathymetric grid was clipped to requested coordinates. USGS 30-meter DEMs were merged into a single grid and analyzed for quality. The dataset was compare to hydrographic and hypsographic contours, as well as USGS, NGS, and COOPs control points. Problematics areas (airport, grid overlaps) were redone by creating TINs using source data. The topographic grid was clipped to requested coordinates. The topographic and bathymetric grids were merged into a single 0.88-arcsecond grid. The 0.88-second grid was compared to the Yakutat AK 2.66-second grid to ensure continuity and quality. A gridmatching graphic (yak3_1.jpg) was produced to verify nest matching for modeling efforts. The final grid was analyzed for blunders, systematic errors, and logical consistency.
