The persistent scatterer interferometry (PSI) is a powerful technique to monitor the line of sight (LOS) deformation with Millimeter accuracy in urban areas. Nowadays, this technique is well established for the sensors ERS and Envisat/ASAR. Nevertheless, the availability of high resolution SAR sensors enables new applications which require new estimation principles. Application test cases for the...
Persistent Scatterer Interferometry is a well-known technique to obtain displacement rates in urban areas from a stack of SAR interferograms. Besides the original method introduced by A. Ferretti, C. Prati and F. Rocca in the late 1990's, which estimates the displacement rates and DEM corrections by an ensemble coherence maximization approach (periodogram) based on a common master image, several other...
This paper presents the integration of the world's sensor networks. These should help monitor the health of the globe. Environmental monitoring satellites today knits a complex web of orbits around the Earth, providing analysts on the ground with continuous updates on cloud cover, storms, minute changes in gravity, land profiles and a wealth of other data
