(ArcToolbox<Spatial Analyst Tools<Surface<Contour) The layer's properties were changed to display the unique values for the contours. Applying the Definition Query's Query Builder, the contour polylines were isolated and exported as a shapefile. 2019-05-19T00:00:00 O'Conner, Robert 808-725-5083 Robert.OConner@noaa.gov processor The polyline was incomplete, or unconnected, thus unable to represent a full isobath area at this depth. The Editor tool was used to connect vertices to close the isobath, using hillshade and other contours as guides. (Hillshade was generated using ArcToolbox<Spatial Analyst Tools<Surface<Hillshade) The completed polyline was converted to a polygon using Arctoolbox's Feature to Polygon Tool. (ArcToolbox<Data Management Tools<Feature<Feature to Polygon) Using Arctoolbox's Smooth Polygon Tool, the polygon was smoothed using a Bezier algorithm. (ArcToolbox<Cartography Tools<Generalization<Smooth Polygon) The smoothed polygon was reprojected to GCS WGS 84.
