Proceeding of the Joint International Symposium on Deformatuon Monitoring. 2-4 November, 2011. Hong Kong. China. Report. The intention of this paper is to outline the application of multi-temporal helicopter-based laser scanning over an approximately 100 hectare earthflow in the Interior Plateau of southwest British Columbia, Canada. Since 2006, Terra Remote Sensing Inc. has collected seven high-resolution LiDAR and orthophoto datasets over the Fountain Slide and is scheduled to continue surveys through 2011. The slide is situated between a major highway transportation corridor and a BC railroad line. The British Colombia Ministry of Transportation and Infrastructure (BC MoTI) has used the temporal LiDAR and orthophoto data in combination with in-situ slope inclinometer data to monitor the slide's movement. This paper will outline the methodology of LiDAR data collection, data processing and integration with geotechnical engineering software applications. The paper will also discuss the approach taken by the BC MoTI to ensure safety along the affected transportation corridors, which includes road re-alignments and the implementation of innovative slope stability techniques
