I’m looking for suggestions on waypoint optimization for an orthomosaic mission where a portion of the roof is obscured by tree overhang. There is enough clearance to fly beneath the canopy to capture the surface, but this requires dropping elevation for the intersecting waypoints. My main concern is whether this change in altitude will cause significant GSD (Ground Sample Distance) variance or alignment errors during the stitch. Has anyone successfully managed mixed-elevation waypoints for a single ortho, or found a better workflow for tree-masked roof sections?
I’ve flown mapping missions with varying altitudes. Also spiral missions with altitudes ranging from 15 ft AGL to 150 ft AGL.
Orthos and 3Ds both turned out great, using WebODM to process the images.
