Hi,
We are having issues where we get large deformations in our DSM due to shadows of various objects like light posts.
See the attached two images. In the top left you can see the shadow from the light post, and then in the DSM you can see the deformation from this. The ground is known to be smooth yet, the DSM shows it as deformed right where the shadow is.
Does anyone know a way to process the data without this occurring? What settings might we try?
We believe that this effect is particularly pronounced when the aircraft has taken a long time to return and the shadows have moved and/or the surface is fairly featureless.
