Object-based detection of hazards to the European gas pipeline network using SAR images
conference paper
In this paper the results of a study for a hazard detection system for Europe’s extensive high pressure gas mains transmission systems are presented. The system is designed to trace uncontrolled digging, ploughing, excavating activities using draglines or other machinery, construction works and planting of trees near pipelines using remote sensing. The architecture of the system consists of three stages: SAR and optical change detection, change categorisation and change classification. In case of SAR change detection two cases were worked out, one for airborne sensors and one for spaceborne sensors. For the airborne case an average percentage of detection was found of 74 %. For the spaceborne case this figure was 37 %. Results of optical change detection are not fully elaborated yet, but some are shown. Additional reduction of false alarms takes place in the change classification stage. The study is part of the European Commission fifth framework project PRESENSE - Pipeline REmote SENsing for Safety and the Environment.
