Dear List,
I have some ALOS Prism Triplet imagery, L1B1 which come in four CCD images
per look angle (a total of 12 images). I've been able to produce DEM's from
the pairs of strips e.g. Nadir 1 + Backward 1, Nadir 2 + Backward 1 which is
necessary for this processing this product level, according to Phillip Chen.
However, the process is time consuming and there are slight differences in
the DEM produced by each stereo pair. Ideally, I would like to produce a DEM
from the whole scene, since Orthoengine 10.2. will stitch the data together
on import. However, whenever I do this, I get strange results in the output
DEM. Has anyone found a solution to this ? Ideally I suppose I would have
the level L1B2R product in which each look angle is a single scene, but I do
not.
Thanks in advance.
Paul
