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 |
