Dear colleagues,
I made some efforts to produce interferograns from ALOS 1.1 SLC data. Since I have to make temporal analyses I need to process about 20 scenes. So the simple answer is to make a graph, but surprisingly i can nor find in the graph builder the coregistration tool I’ve used via Radar->Coregistration->Coregistration.
Any ideas how to overcome this?
Thanks for your input.
Coregistration consists of two modules, cross-correlation and warp. You can build them in the graph builder similar to the arrangement of the GUI tool:
Actually I’m working on ALOS SLC data for small island in Antarctic trying to check if interferometry could be of use. By now the results are not promising for the large amount of water present in the data. I’m not aware how to limit processing just to the places having elevation above sea level i.e. some masking.
This is what I did the day before yesterday with only difference i did multilooking before snaphu export.
But I suppose the problem is that for sea surface the coherence is quite low (mainly in the interval 0.05 - 0.2) which reflects on the whole processing.
