| Résumé | (disponible en anglais seulement)
Seasonal surface displacement was mapped by the Canada Centre for Remote Sensing and the Geological Survey of Canada for Yellowknife and the surrounding area
using satellite interferometric synthetic aperture radar (InSAR). RADARSAT-2 Ultra-fine scenes acquired on May 21, July 8, August 1, August 25 and September 18, 2010, were interferometrically stacked and the total amount of summer vertical
displacement was calculated. This open file presents the relative surface displacement in both map and digital ArcGIS form. The calculated values are portrayed in terms of relative displacement that has been classified as stable, low and medium
downward displacement and upward displacement. At some locations a significant change in surface characteristics results in a loss of interferometric coherence and no values were calculated. Surface displacement may be from natural and human-induced
processes.
This dataset provides spatial context for the variability and relative magnitude of seasonal surface displacement within the Yellowknife area. |
