Camera lock
- ND filters off by default; no digital zoom, HDR, or AEB.
- Full 5472 × 3648, 3:2, wide camera. Use JPG for the 2 s cadence; DNG needs at least 5 s or a settled capture.
- Manual 1/1000 s target; 1/800 s moving-flight floor.
- Prefer f/4; open to f/2.8 before allowing a slower shutter.
- ISO 100–800; lock white balance and focus.
Metric control
Require RTK FIX before production routes. Preserve raw satellite observations and flight logs; record the base/NTRIP correction source, datum, and firmware; measure independent checkpoints.
Passes
Planned heights, gimbal angles, overlap, speed, and view diversity| Pass | Geometry | Cadence |
|---|
| Global block | 30 m AGL · −90° nadir + four −45° to −50° oblique headings · 83/80 overlap | 1.5 m/s · 2 s |
|---|
| Upright detail | 10 m AGL · −25° · N/S/E/W · ≤5 m line spacing | 1 m/s · 2 s |
|---|
| Facades | 8–15 m stand-off · −10° to −25° · five azimuth offsets | 1–2 m stations · ≤0.5 m/s or settled hover |

Facade azimuth offsets: −60°, −30°, 0°, +30°, +60°.
