COSMO-SkyMed MultiTemporal Coherence
over Concepcion area.
This map shows potential changes that have occurred between the acquisition
dates of the COSMO-SkyMed Spotlight-2 images (28.02.2010 - 08.03.2010).
Such potential changes have been faced with optical VHR pre-post earthquake
images.
In MTC map, green elements detects areas where the coherence is low and
the backscattering value is significantly higher in the post image rather
than in the pre image. Viceversa, red areas detects areas where the coherence
is low and the backscattering value is significantly higher in the pre
image rather than in the post image. Red and green areas are areas where
a change could have happened, in the urban areas maybe caused by the earthquake.
Blue elements are areas where the coherence between the two images is high
and therefore should not have changed that much.
- Red: Pre-event
SAR detected amplitude (26.04.2009)
- Green: Post-event
SAR detected amplitude (15.01.2010)
- Blue: Interferometric
