thanks for the feedback. I went on and tried with different sections of my point cloud. Started out really small, a few thousand points, and worked my way up. At this scale, it still worked as expected (I recolored class 72, embankments to yellow to make a clearer distinction):
but going back to the original size, the same thing happens.
A few things do not make sense:
- From your message I gather that the ground classes should never be reclassified, but even if I take them up in the ignore_class, it is still changed
- Another extended class, 64 is also reclassed (see green arrow) (also in ignore list), but other extended classes are not.
- they are both reclasssified to a value that makes absoluetly no sense: if for some reason it should be classified, it should at least be class 3.
The only thing that all the correct files had in common, was that I extracted the sections with CloudCompare and saved the resulting sections. So I tried simply saving the whole file via CC, and then it worked :o
So there is something in the original file that makes lasheight behave the way it does. Is it possible for you to find out what it is exactly if I send you the file?
