Contents

This open file publication contains information on seasonal surface displacement for Iqaluit and the surrounding area for the years 2011, 2012, and 2013. 

Data were derived using differential Interferometric Synthetic Aperture Radar (DInSAR). RADARSAT-2 data acquired over Iqaluit were used for the DInSAR analysis.

Conventional differential InSAR (DInSAR) makes it possible to detect very small ground surface movement, on the order of centimetres, for every pixel over large areas, providing a way to assess active layer and permafrost dynamics.
