what footprint to show for high-res data ?

[falkamelung]

1. There have been some changes to the workflow. Can you please remind me what you use for drawing the blue box and what the footprints are used for?

From your screenshot I see it uses mintpy.subset.lalo for the high-res data. It rather should use miaplpy.subset.lalo. If this does not exist, then use mintpy.subset.lalo. If that does not exist then use what it regularly uses.

2. For the high-res data it used to be drawing the swath/scene footprint (much bigger than the actual data area), and when you click on it you got the smaller, data area. Is this needed? I don't see much benefit of showing the swath. The current data_footprint is a straight N-S-E-W rectangle although the data area is inclined in satellite-flight direction (swath-type but smaller). It would be preferred to show the inclined actual data coverage. I wonder how to do this. Assuming that modifying data_footprint is not a good idea, shall we introduce a new field such as tight_data_footprint ?

One advantage would that it will be straightforward to discern the basic LOS (current) data from vertical and east-west. The latter would always have a straight rectangle.
