In the FP7 DORIS project, one of the main tasks was devoted to generate and deliver relevant and accurate maps and timely information for managing the different civil defence phases involved in the onset of ground deformation. TRE ALTAMIRA provided ground motion data over different periods of time by the use of Synthetic Aperture Radar Interpherometry on sites of Rácalmás and Dunaszeksö, where high loess river bank collapses along the Danube with deep seated landslides affected urban areas and infrastructures, and former volcanic mountain with several ground deformation events occured. Several radars and time periods where used to obtain the maximum information: L band mid‐resolution sensors ERS and ENVISAT for 1992–2002 and 2003–2010, ALOS sensor for 2007 and 2011 and X band high‐resolution TerraSAR‐x for 2011. Their combination allows to improve and optimize the information and to correlate radar with on‐site data, improving the knowledge of the phenomena and its triggering as well as the in situ observational method approach.
