High‑Resolution Capture: Mapping, Panoramas, and HDR
Blend nadir passes with slight oblique rows to capture façades and edge detail. Maintain 70% overlap and constant ground sampling distance. Calibrate focus at cruising altitude to prevent soft seams and warping.
High‑Resolution Capture: Mapping, Panoramas, and HDR
Lock exposure brackets per node, then yaw in fixed increments with a consistent tilt. Shoot a clean horizon row to reduce stitching errors. Use a nodal offset test beforehand to minimize parallax complications.

Build a distortion and vignetting profile using test charts at altitude. Apply uniformly before stitching to avoid ghosted edges. Flat‑field correct skies to prevent banding in large, softly graded gradients.
