Abstract
A pipeline surveying system including a pipeline pig can accurately provide a pipeline profile after correlation with a previously determined GPS survey. An inertial measurement unit located in the pig determines a pipeline profile as it travels through the pipeline and correlates the measured profile with the GPS survey.
