DRONE OPS Mission Planning · Recording · Execution

Tools, workflow, and reference for drone survey, heritage capture, and cinematic recording operations across Dartmoor, Cornwall, and beyond. From pre-flight mission planning to 3DGS pipeline handoff.

01 Planning tools

MISSION SOFTWARE

The tools that matter for planning autonomous mapping and recording flights — especially for DJI drones that support waypoints but ship with no planning software.

Free
Desktop · Win / Mac
WAYPOINT OS
Draw a boundary, auto-generate camera-aware flight lines, export a DJI-compatible KMZ. The only proper mission planner for Mini 4 Pro, Air 3, and Mavic 3 — DJI provides no SDK-based alternative for these models.
KMZ export Camera-aware overlap Mission splitting Offline capable Local data
NTRIP · Subscription
PILOTBYTE RTK
Real-time GNSS correction network delivered via NTRIP. Connects RTK-capable drones and receivers to base station corrections without deploying your own base station. Sub-5cm horizontal accuracy under good conditions.
RTK corrections NTRIP stream DJI RTK drones Emlid Reach RTCM output
Mobile · Controller
DJI FLY
The execution layer. Loads the KMZ exported from Waypoint OS, runs the autonomous mission, handles obstacle avoidance, and records footage. Waypoint OS plans it — DJI Fly flies it.

METASHAPE
Photogrammetry processing for survey outputs. Takes the captured imagery from a Waypoint OS mission and produces dense point clouds, DEMs, and orthomosaics for client deliverables or 3DGS pipeline handoff.
Point cloud Orthomosaic DEM → COLMAP / 3DGS
02 Survey workflow

MAPPING MISSION FLOW

End-to-end workflow for a heritage survey or mapping mission — from pre-flight planning through to 3D reconstruction handoff.

01
PLAN
Open Waypoint OS. Select drone, draw site boundary, set altitude and overlap. Export KMZ.
Waypoint OS
02
PREP
Transfer KMZ to controller. Check weather, NOTAM, airspace. Lay GCPs if sub-5cm accuracy needed.
Pre-flight
03
FLY
Load mission in DJI Fly. Verify parameters. Execute autonomous grid. Monitor battery and coverage.
DJI Fly
04
EXTRACT
Pull footage from SD card. Run ffmpeg frame extraction at target fps for photogrammetry input.
ffmpeg
05
PROCESS
COLMAP feature matching and sparse reconstruction. Feed into 3DGS trainer or Metashape for deliverables.
COLMAP → 3DGS
06
PUBLISH
Trained splat deployed to Hylas Spatial. Scene card added to atlas. WebGL viewer live.
