________

This Open File presents seasonal surface displacement and embankment grade calculated for a 48 km section of Highway 3 (km marker 282 to 330), located to the west of Yellowknife. Satellite interferometric synthetic aperture radar (InSAR) was used to calculate relative surface displacement from May to September of 2010 along the highway corridor. Airborne light detection and ranging (LiDAR) data were also acquired on August 22 and 24, 2010 to measure road elevations, calculate embankment grade and map raised ice-rich ground and wet terrain. The derived data products accompanying this Open File are presented in graphical and digital format.
