EarthView® InSAR v3

Changes included in EV-InSAR (version 3.0)

·         A new version of Python, and (on Windows) a new version of MKS Toolkit (v8.6) have b een incorporated into the product.

·         The processor was not reading the Doppler centroid and rate values correctly from “flipped” images produced by APP (on descending passes, APP flips the image from sensor geometry to a nominal “North-up” orientation). This in turn caused problems with image resampling and co-registration. The problem is most obvious with high Doppler centroid (low latitude) RADARSAT descending passes. In this case the coherence is poor, and shows strong banding.  We recommend reprocessing any descending RADARSAT pair at latitudes of less than 25 degrees.
