Wide area map initiative of Terrafirma

SPACE SEGMENTSENTINEL 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
