@Boris I have run into this as well. KPMD photogrammetry / TIN overlaps runways which makes adding heightmaps and/or runway profiles get really crazy bumpy. turning off photogrammetry, the same heightmaps and runway profiles are smooth as silk. would be great to be able to at least exclude TIN with a custom airport area. Other areas that don’t have photogrammetry work as expected with heightmaps and runway profiles. can we at least get the KPMD area photogrammetry excluded even if the tools don’t enable us to do it? happy to share example privately.
