| Abstract | ALOS-PALSAR interferometric pairs are examined to determine the potential for monitoring ground movement in permafrost environments. Data sets are from the Herschel Island, Yukon Territory, northern
Canada. The coherence levels of PALSAR pairs are shown to be exceptionally high in this northern environment, even with one year separation, and with very large baselines, close to critical values. The importance of an accurate digital elevation
model is shown in the successful detection of seasonal and long-term ground movement trends. |
