Geographic Engineering Management Systemby Harold L. Smith, Memphis District, Corps of Engineers, Memphis, United States,
Abstract: The Memphis District Engineering Division is developing a GIS type data base as part of a Geographic Engineering Management System (GEMS) to assist both the District and the Lower Mississippi Valley Division in executing the Master Plan for Channel Improvement on the Lower Mississippi River. The Master Plan includes both construction and maintenance of dikes, revetments, dredging, and numerous miscellaneous structures, along 355 miles of the Mississippi River. The engineering data base will include an aerial photo base map, as-built drawings of existing structures, horizontal and vertical survey control, historical as well as current topographic and hydrographic surveys, a relational data base of existing and planned features as well as budget, environmental, 404 permit information, and real estate data. GEMS will be developed on 3050 and 6040 Intergraph workstations utilizing numerous off-the-shelf Intergraph software packages. With an annual engineering and design budget for the Memphis District project of $4.5 million, the estimated $600,000 developmental cost will be saved from increased productivity and reduced manpower within 3 years after full implementation. In 1989 Intergraph completed a pilot project demonstrating the use and capabilities of an engineering data base on a 3-mile reach of the Mississippi River. This project answered many questions and concerns about data storage, data management, engineering and design, user access, and overall system management. A contract was awarded in September 1990 for an additional pilot project and subsequent full development of the data base.
