Abstract
Persistent Scatterer Interferometry (PSI) is a remote sensing technique to measure and monitor land deformation from a stack of interferometric SAR images. Its main products are the deformation maps (maps of the average displacement rates), the deformation time series and the maps of the so-called residual topographic errors. In this paper, we describe a new product derived from X-band PSI: the thermal deformation maps. This paper briefly describes the thermal component of the PSI phase observations and outlines the approach to estimate the thermal maps. The last part of the paper discusses three examples of thermal maps derived from a stack of 28 StripMap TerraSAR-X images that cover the metropolitan area of Barcelona (Spain).
