What makes this interferogram stand out, according to Nico Adam, the DLR scientist who headed the effort, is that the SARs on ERS-2 and Envisat operate at slightly different frequencies, enough to ...

An interferogram can be considered as the difference between two SAR images acquired over the same area at different dates. The color of a pixel represents how much the land surface has moved ...

This ‘interferogram’ combines 19 scans by Sentinel-1A’s radar over the San Joaquin Valley in the US state of California. Covering an area of about 30 000 sq km, a number of oil fields are ...

The interferogram on this page was produced by COMET's partners - the Norut research institute in Tromso, Norway; and PPO.labs in The Hague, Netherlands.

The interferogram will be refined in the coming days. It will be used to map damage and landslides. INSARAP will also derive a model to interpret the quake's "anatomy".

This flattened cross-sensor-interferogram has been created from a mixed image pair with four days’ temporal separation acquired by TerraSAR-X and PAZ (StripMap scenes from Nov. 22-26, 2018). The area ...
