Spectra Energy Inc. is proposing to construct a pipeline to transport liquefied natural gas (LNG) across northern British Columbia from near Fort St. John to Prince Rupert. Worley Parsons, one of the project engineering consultants, invited two of the geomorphologists at Palmer Environmental Consulting Group Inc. (PECG) to join their project team as terrain stability mapping specialists.
Robin McKillop, M.Sc., P.Geo. and Derek Turner, M.Sc., Ph.D. are currently completing detailed terrain stability mapping and geohazard identification along hundreds of kilometres of proposed pipeline corridor, based on high-resolution stereo aerial photography, bare-earth LiDAR hillshade models and surficial geotechnical field data. Our mapping is made particularly efficient by using a softcopy stereo-interpretation program integrated with an ArcGIS platform, which enables instant viewing of multiple spatial data overlays.
Our interpretive work provides the basis for estimating cut-and-fill requirements, identifying slope hazards requiring more detailed on-site assessment, and locating potential aggregate resources for pipeline construction.
