| Abstract | The economic importance of the railway transportation corridor through the Thompson River valley, British Columbia, together with the need to understand and manage the safety risks related to
landslides, make on-site investigations of landslides a strategic priority for the federal government and railway industry. Here, we compare and evaluate the agreement and reliability of ground motion measurements from several complimentary landscape
monitoring approaches. Interferometric analysis of satellite synthetic aperture radar datasets, global navigation satellite system measurements, unmanned aerial vehicle photogrammetry, and benchmark ground observations provide valuable baseline
spatial and temporal information on movement of the North Slide toe slope in the vicinity of critical railway infrastructure. Monitoring unstable slopes and infrastructure at risk is a cost-effective hazard management practice that also provides
important geoscience information to help develop appropriate mitigation and adaptation measures. |

Monitoring unstable slopes and infrastructure at risk is a cost-effective hazard management practice that also provides important geoscience information
to help develop appropriate mitigation and adaptation measures. |
