Pipeliners focus on automated class location studies for safety. R.M. White and R.H. Hughes. Pipeline Gas J., September 1994, 221(9), 81--83.

Increased safety precautions are being imposed on natural gas transmission companies as a result of recent pipeline incidents. Class location studies are described and the advantages of automation techniques and computerized tabular computations are reviewed. Data acquisition using a combination of automated mapping, facilities management and geographic information systems (AM/FM/GIS) is described. The AM/FM/GIS technique also supports new imaging technologies for displaying aerial photography. Pipeline operators are now using this technological approach to meet more stringent legislative requirements imposed by the US Department of Transportation.
