Satelite radar interferometry for operational geodesy: a SWOT analysis

Hanssen, R. (Speaker)

Activity: Talk or presentationTalk or presentation at a workshop, seminar, course or other meeting

Description

Satellite radar interferometry (InSAR) has evolved to a frequently used geodetic technique, particularly for measuring and monitoring the kinematic behaviour of its measurement points. Applications first started from analysing geophysical processes (tectonic, volcanic, cryospheric or atmospheric phenomena), but are rapidly expanding to the measurement, monitoring and analysis of the structural health of constructions and other man-made objects. In this presentation, we will perform a SWOT analysis of the state-of-the art in InSAR: Strengths, Weaknesses, Opportunities and Threats. We will discuss issues related to the difficult interpretation of the InSAR data, and provide methods to cast InSAR in a conventional geodetic framework. We will address the reference systems involved, and how we can relate InSAR observations to a conventional datum. Experiences from different experiments in the Netherlands will be shared.
