            1 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.
