Pig Locating is the process of determining the location of a pig that has not continued to progress along the pipeline as expected or verifying that a pig is in the expected location for example a pig receiver.

Pig Tracking is used to confirm the passage of a moving pig at a particular location(s) most commonly by a team of operators using "leapfrogging."
