CurrentPractices
AccordingtotheUSDepartmentofTransportation1,therewere1,718,407milesofoilandgaspipelinesin2012.Newpipelinesarecurrentlyunderconstruction,andeverysinglemileofpipelinerequiresroutineinspections.

• Cost:AnnualandbiweeklyaircraftpatrolsflyingovertheROWtomonitorforencroachmentsisexpensive.
• Accuracy:Humananalysisduringflyoverissubjecttoerror.• Time:Changedetectionandencroachmentmonitoringaretime-intensiveprocesses.
