Abstract Nautical Mapping with the United States Army Corps of Engineers Track: Defense and Intelligence Author(s): Ralph Scheid, John Merritt In November 2007, USACE and 3001 completed the 2007 Flood Control and Navigation Book for the Lower Mississippi River. The data collection for a project of this scope included hydrographic surveys to determine shallow and project depth areas, stereocompilation and GPS to determine current location, condition and ownership of all facilities and docks, and GPS survey to collect present locations of all navigation aids and wrecks. ArcGIS and MPS Atlas were utilized in the production of the maps and a similar effort is underway by the USACE on the Upper Mississippi River.
