What is this data?
ERS-1 is the European Remote-Sensing Satellite-1 it was operated by the European Space Agency, ESA , which launched the satellite in 1991 carrying an array of earth-observation instruments. SAR (synthetic aperture radar) instrument operating in C band can detect changes in surface heights with sub-millimeter precision.
ERS-1 failed in 2000, far exceeding its expected lifespan.
Where is it available?
ERS-1 SAR images covering Iceland were collected between 1992-2000 and are available on ‘Askja’ remote computer (askja.rhi.hi.is) at The University of Iceland. For access and a list of available images please contact Freysteinn Sigmundsson (fs@hi.is).
