Introduction to TerrafirmaGSE TERRAFIRMA Service coverage 2009-2011 ESA Terrafirma : biggest GMES terrain motion hazard information service, Altamira is its project manager Sser The current (third Stage) of the project is lead by Altamira Information; it has a budget of 3.5 M€ over 3 years.
InSAR motion mapping basics and current projects Results Second measurement (afterwards) Radar satellites First measurement Ground movement rate maps Superimposition of waves to detect differences In terferometric = S ynthetic A perture R adar High resolution radar system = Ground movement time series Difference between two measurements indicates ground movement over time Travel phase between ground and sensor gives mmtric distance 3 cm InSAR ground motion data utilised in a multiude of geo-hazard focused projects PanGEO - 3 cm
Wide area map initiative of Terrafirma SPACE SEGMENT SENTINEL 1 • Traditionally InSAR analysis of local area or of single phenomena = inefficient • Advanced algorithms to process full image data frames rapidly and allow multiple applications of InSAR to Geo Hazards • Methodology will be applicable to Sentinel-1 data to allow rapid wide area motion maps to be produced • Method for integrating multiple track datasets into a single motion map • Resulting datasets can be freely viewed • To allow continental scale and future worldwide ground motion dataset NEW CONCEPT and NEW ALGORITHMS for a NEW PRODUCT Process large land-masses as one dataset – one dataset ….. many applications
