Process_Step:

Process_Description:

Data was downloaded from NOS/NOAA Hydrographic survey website and converted to GIS format. Data were reprojected and clipped to study area. A TIN was created from mass points using the Point Judith shoreline as a breakline feature (elevation = zero). TIN was converted to a ArcGIS GRID with 10 ft pixel resolution
