Opportunity for scientific use of PAZ data

Just for information for anyone interested in making application for scientific use of PAZ SAR data (the third satellite of TerraSAR-X constellation - https://directory.eoportal.org/web/eoportal/satellite-missions/p/paz).

One could apply here - http://www.inta.es/WEB/paz-ciencia/en/announcement-of-opportunity/


I received the first delivery today and just wanted to share some first impressions.
Three SpotLight images of the city of Hue, Vietnam
red = 20191008 descending, small incidence angle
green = 20191009 ascending, small incidence angle
blue = 20191014 ascending, large incidence angle


Impressive Andreas, thanks!

thank you. The data quality is great, as expected, as it is almost identical to TerraSAR-X SL data.
I was granted 24 products both ascending/descending and small/large incidence angles and try to find out which configurations (and threir combinations) are the most valuable for the mapping of buildings and urban flooding.

This is the coherence [0 - 0.75] in ascending (top) and descending (bottom) direction, both at around 25° incidence angle. As soon as I get more images, I will be able to analyze how the incidence angle affects backscatter and coherence of the urban area.

Are the products in SLC format?

yes, single look complex, HH polarization

What consistency values ​​(Coherence) are optimal for applying a deformation or subsistence with SAR SENTINEL 1

there is no absolute limit (the higher the better), but besides high coherence, what is more important is the availabiliy of good coherence over wide areas, and not just single patches), because this is needed for the later unwrapping.
But I think this discussion does not belong in here.

@Oliverius I suppose 0.4 for coherence could be fine. You can also experiment with BandMath setting different values for coherence masking the unwrapped image.
