DJI Terra quality report excluding some ortho imagery

[rtk350]

I recently did a flight to capture LiDAR data and RGB of a forested area, using the Matrice 350 RTK. We're running into a problem with the quality report generated by Terra. The LiDAR point cloud looks great, however the ortho preview as well as the scene overlapping visual show a significant missing chunk. Is there any way to tell what is causing the exclusion of this area?

Is the area too homogeneous such as being just trees? The other areas have bald spots and roads which would work better with photogrammetry. I have had heavily forested areas not process on different occasions.

What was the flight height (GSD) and were you using nadir or oblique images?

That's definitely possible. Here's an image of the missing chunk, which does look rather uniform. I am flying at 90m/300ft using nadir images

I have had this happen sometimes. But I am surprised that it happened at 300 ft since the larger FOV should allow each image to have more areas to match points in. Flying with all oblique images could help since they will have a larger FOV

Were you using RTK for the flights?
