EarthView® InSAR v3
included in EV-InSAR (version 3.0)
- The coherent target monitoring (CTM) module
(beta release) has now been integrated with the core InSAR
software. The software must be licensed for this module in order for it to
be used. The general release is expected to be early in 2004.
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.
- A mistake in tutorial 5 has been corrected,
which described how to interpret the sign of a change product. This table
has been corrected.
- The option to re-run a given step has been added
to the EV-InSAR GUI in the form of a re-run
- The ability to apply residual phase corrections
to the raw interferogram has been added,
primarily for CTM work.
- Improvements have been made to the way
processing errors are reported.
- Coarse tiepoints now
work properly in the master/slave tiepoint
editor. The use of such points is still discouraged.
- A bug preventing report files from being
generated has been fixed.
- Several reported ENVISAT ingest issues have been
solved. Differential runs using ENVISAT data no longer cause an error
during SAR simulation.
