Railway Right of Way Monitoring and Early Warning System (RailMEWS) Based on Satellite and Aerial Imagery

This report presents the findings of a one-year study that explores the feasibility to use commercially available satellite and other aerial imagery to monitor the right of way of railroads for effects and conditions that could potentially trigger landslides and other geotechnical failures. Two major objectives have been identified: (1) Establish the methodologies for processing satellite and aerial images suitable for detecting and quantifying deformations on the right of way of railways at desired levels of accuracy; and (2) Provide recommendations for the development of a remote monitoring system. An extensive review of existing methods is conducted. Showcase studies have demonstrated that the current satellite technology makes it feasible to monitor the railway infrastructure for large- and small-scale deformations and changes in the ground moisture content with adequate resolution. The satellite analysis results can be superimposed to aerial visual imagery for ease of visual inspection and evaluation. Future work for the development of a monitoring system of the railway right of way needs to focus on verifying the accuracy of the techniques with in-situ measurements through conventional means and quantifying the changes of the moisture content.
