Transmission Corridor Location Modeling

Abstract

The location of corridor rights‐of‐way has been approached by a number of investigators dealing with problems of transmission power lines, pipelines, highways, and other transport systems. A commonly used three step approach in computerized approaches for locating a transmission corridor is reviewed. This three step methodology is widely accepted and employed in virtually all computerized corridor models. Unfortunately there can be significant geometric errors in the actual application of these techniques due to the underlying network representation. The sources of error are discussed and an approach is presented that can measurably reduce such errors. Applications to a hypothetical data set and to a statewide geo‐based inforniation system data base are presented.
