Abstract :
A new approach for the measurement of deformations with SAR interferometry in scarcely decorrelated, long term interferograms is presented. The approach makes use of the interferometric phase information from highly coherent features, mostly of anthropogenic nature. The method has been applied to measure the deformations in a subsiding area in The Netherlands and the results turned out to be in good agreement with those from a pre-existing subsidence model
