I have two ALOS-2 level 1.1 SLCs in CEOS data format. They are in Stripmap-mode and have a temporal baseline of around 2 months. Additionally, I have a “ground truth” lidar data height GeoTiff. I wanted to plot the coherence vs. the lidar height in some sort of a scatterplot. Hence I thought the lidar-data and the coherence-estiamte shoulb be “coregistered” and resampled.
I formed the interferogram according to this procedure:
I need to confess that I didn’t look too much into the processing parameters in that workflow. Now my final result has due to filtering and multilooking some resolution that is completely different from my 10m resolution Lidar height.
Does it make any sense to resample the coherence again to the lidar height or do you think it would be better to resample the lidar height to the coherence estimates?
Any help would be super appreciated:)
