It’s best not to use ignore-gsd, it does cause a lot of problems with many datasets. It really is time for developers to make it really hard to select!
Are there only 5 images in total?
Based on those 5 images, it is quite difficult set of images to work with, especially if there was any wind, as the trees cover such a large part of the scene. Increasing minimum number of features significantly may help.
No, there are 300+ images in total. Will continue uploading the rest of images when the connection is better.
Unfortunately, I’ve also tried only using --dtm and --dsm parameter and the DTM still not produced correctly. But with other previous datasets, it was all fine. I really can’t caught what makes two of them different.
