Example of data formats available in the DMS-Data Manager This example illustrates some of the usable data formats in the Data Manager. First, a georeferenced image of a Geological Survey (USGS) quadrangle (labeled USGS ) provides the underlying base map. An AutoCad drawing () of the authorized channel and disposal sites has been layered on top of the base map. Above the CAD drawing, the east and west jetties are shown as an Arc View shapefile {Jetties, shp). Point data from a comma-delimited X,Y,Z ASCII file () were loaded into the project but not displayed. However, the point data were used to create a triangulated irregular network (TIN) to represent the surface defined by a 1985 bathymetric survey. The TIN has been color coded based on the given elevations to illustrate depths within East Pass. As this single screen shot shows, multiple data formats can now be brought together to provide a detailed view of a project. With the data assembled in one place, the user can first make some simple observations. First, areas of persistent shoaling become easy to identify. Although personnel with extensive experience on a given project are likely familiar with such areas, documentation in a graphical format he
