CHATTANOOGA ENGINEERS CLUB http://www.utc.edu/~engrcs/cec/cec.htm Volume LI May 15, 2000 12:00 noon Number 18 The Cellar at Union Square THIS WEEK__________________________________________________________________ Gary Forrester, project engineer on the Apison Substation, will present the construction and engineering details on EPB's newest source station. Apison Substation is one of eight EPB substations in our area. LAST WEEK___________________________________________________________________ Alan Voss coordinated our visit to TVA Map Store, http://www.tva.gov/mapstore/. The Map sales office is part of Geographic Information and Engineering (GI&E) (formerly Maps and Surveys) facilities, which provides a public sales outlet for all the TVA Map products. These include aerial photography, from the 1920's to the present, topographic maps, navigation maps and charts, recreation maps, hiking maps, region and area maps, TVA property maps, and digital topographic maps. We were also introduced to the production facilities GI&E see the latest in computer mapping techniques, and the production of Geographic Information System (GIS) databases. The tour included a visit to the Remote Sensing area, where flight photography, using infrared sensing, records and translate non-point source data. With some generally accepted assumptions, the information is to verify environmental data, such as watershed and water vegetation. G&IE are involved in many power projects. Maps are needed by power operation in environmental permits. Maps and other documentation have seen the most growth in power projects. In delivery the data needed for many power projects, for the design of transmission line, as much information as possible is gathered. Some data will also benefit other projects. We had the opportunity to also hear from Bill Massa, former chief of Map and Services. He is a walking history book of the Mapping efforts of TVA, as well as some of the mapping done for the federal government. TVA Mapping supplied foreign maps during WWII, Korean War, and the Vietnam War. TVA also mapped possible invasion routes in New York State, Texas, and the Carolinas for the Department of Defense. During the height of its operation, Mapping employed 20 surveyors, and 82 mapping employees. The personnel and project load has decreased. It has been 15 years since some of maps have been updated. There is no longer a periodic update schedule for TVA maps. Over 30 members enjoyed a very informative tour. Many purchased various maps from the Map Store.
