A G.I.S. for Cross Country Pipelinesby Edward B. Nicholson, Columbia Gas Transmission, St. Albans, United States,
Abstract: Faced with an increased workload, greater information demands and a limited staff, the Civil Engineering Section of Columbia Gas Transmission is trying a different approach to the selection and mapping of proposed natural gas pipeline routes. We are having d digitized database created from aerial photography along a proposed corridor. The proposed pipeline route and property information is then entered into the database from information gathered during field reconnaissance. A preliminary strip map is then prepared for use in the actual field survey and to begin the permitting process with the appropriate regulatory agencies. Using this database, we are creating some of the vast array of drawings necessary for pipeline construction. The database structure allows different information to be shown on each map based on the purpose of the map. This paper explores our experiences with this technique.
