GPS pipeline mapping services and experience of Controlwork and Merrett Survey Partnership

NEW! Mapping without an IMU

CASE STUDIES Pipeline GIS for Class Location Survey. Navigational GPS survey for asset management risk/threat analysis. >>more... Pipeline profiles to determine ground profile and cover levels across both the river bed and flood plain. >>more...
Field work: GPS pipeline mapping GIS asset data collection New pipeline route /corridor mapping Aerial mapping from photogrammetry Airborne laser scanning ( LiDAR) As-built surveys Site survey for development projects Oilfield mapping - flowlines / gathering stations / compressor stations etc		Experience: Why wait for the problems to occur, when we have the solutions already in place? Through long experience (our own, plus supervising other surveyors worldwide) we have witnessed all the problems, and we know how to prevent them. We have a detailed knowledge of the pipeline mapping process - how the pig works, the need for reliable high accuracy GPS, the correlation of in-line MFL data to above ground features.

Processing: Network adjustments. Datum transformations - horizontal and vertical. Geoid / ellipsoid separation models / conversions. Format changes for geo-referenced data.		Consultancy & Training: Advice on pipeline mapping. Training of pipeline operators and integrity management staff in GPS, survey and geodesy. Audits of third part survey companies. Pre- qualification assessment of surveyors. Troubleshooting - can we solve the problem using the data you have already ?
