Surface Movement Monitoring of Underground Construction in Budapest, Hungary

TerraSAR-X-based surface movement assessment performed during the construction of a new subway line in Budapest, Hungary.

Significant surface displacements of up to approx. 10 mm per year along the new track have been observed especially in the vicinities of the subway stations, reflected by the yellow and red colouring in the image. The line-of-sight velocity was derived by persistent scatterer differential interferometry of 43 TerraSAR-X StripMap acquisitions recorded between October 2008 and April 2010

The background displays an optical image acquired on September, 22nd, 2010 by SPOT5.
