6 tasks, each one witnessed by the sources that watched the job — and behind every one, a prompt you can use tonight.
You usually start 1–2 hours before sunset to plan and upload the mission. That means checking the flight plan, battery levels, camera settings, and NOTAMs (airspace notices) for your area.
After dark you launch drones, fly pre-planned routes to capture overlapping night images, and land to swap batteries and memory cards. Back at the van or office you download imagery and run quick checks in PIX4Dmapper or PIX4Dcloud to confirm coverage before finishing.
You will fly commercial drones that support low-light cameras and autonomous waypoint missions. For processing, PIX4Dmapper is used on a laptop to turn night aerial photos into georeferenced maps; PIX4Dcloud shares and reviews results online.
You may also use the drone manufacturer’s ground control app for planning and a traffic-awareness tool (like ADS‑B receiver or DJI AirSense) to stay compliant with airspace rules.
Mission planning means setting flight altitude, speed, camera overlap, and exact waypoints so night images cover the target area. You plan these in the drone app and export photo sets for PIX4D processing.
You also check air traffic restrictions and local laws (NOTAMs, temporary flight restrictions), get any needed permissions, and schedule flights when light conditions match your survey goals (e.g., after midnight for reduced traffic).
AI can help sort images, enhance low-light detail, and classify light sources (streetlamps, signage). You feed cleaned images into PIX4Dmapper for structure-from-motion; AI tools can then assist with labeling or anomaly detection.
Risks: AI can misclassify bright reflections as light sources. Always verify AI outputs by spot-checking originals and use human review before publishing results or decisions.
Start with a basic drone pilot certificate from your national aviation authority (e.g., FAA Part 107 in the U.S.). Then take a course in night operations and aerial photogrammetry, and practice mission planning in your drone’s app.
Learn PIX4Dmapper basics (online tutorials) and PIX4Dcloud for sharing results. Training in GIS basics and map reprojection helps when you turn photos into light‑pollution maps.
Attention to detail in mission planning and image overlap is critical: good surveys need consistent altitude, exposure, and 70–80% image overlap for PIX4Dmapper to build accurate maps.
Also important is airspace compliance—regularly checking NOTAMs and flight rules—and basic image processing skills in PIX4D tools. Good surveyors double-check geotags and verify outputs against raw photos.
