Undertaking drone surveys and mapping in close proximity to airports poses unique challenges, particularly due to the strict regulations governing airspace safety. Airports operate under a 3NM (5.5km) exclusion zone during their operational hours, making it difficult for standard drones to perform critical survey and mapping tasks. However, advancements in drone technology, particularly LiDAR-equipped drones, have opened up new opportunities to overcome these obstacles and carry out efficient surveys even during nighttime hours.

Challenges near Towered Airports

Airports, especially those with control towers, are essential hubs for travel and commerce. To ensure the safety of aircraft and passengers, aviation authorities enforce a 3NM exclusion zone around these towered airports while they are in operation. This exclusion zone restricts drone operations during the day when most surveys and mapping tasks typically occur.

Nighttime Operations: A LiDAR Advantage

One significant advantage of LiDAR-equipped drones is their ability to operate effectively in both day and nighttime conditions. This unique feature circumvents the limitations imposed by the exclusion zones and allows for survey and mapping tasks to be performed when traditional photogrammetry methods are hindered.

​

Key Benefits of LiDAR for Nighttime Surveys:

1. Enhanced Visibility: LiDAR technology uses laser pulses to create highly accurate and detailed 3D maps, making it independent of natural lighting conditions. This means LiDAR-equipped drones can function effectively in low-light and nighttime environments.

2. Continuous Operations: Unlike photogrammetry that relies on daylight, LiDAR-equipped drones can continue surveying and mapping throughout the night. This is especially valuable for time-sensitive projects or those requiring minimal disruption to daytime activities.

3. Safety: Conducting surveys near busy airports during nighttime hours minimizes the risk of interfering with air traffic and enhances overall safety for both drone operators and aviation authorities.

Beyond Airports: Nighttime Street Mapping

LiDAR-equipped drones aren't limited to airport proximity. They also offer an ideal solution for nighttime street mapping and surveying. During the night and early morning hours, when traffic on the streets is minimal, these drones can capture accurate data for various purposes, including urban planning, infrastructure development, and traffic management.

Conclusion

The 3NM exclusion zone around towered airports presents a significant challenge for traditional drone survey and mapping operations. However, LiDAR-equipped drones have emerged as a powerful solution to overcome these obstacles. With their ability to operate effectively during both day and nighttime hours, they offer a versatile tool for various industries, from aviation-related surveys near airports to nighttime street mapping. Embracing this technology allows for increased efficiency, safety, and flexibility in surveying and mapping tasks that were once hindered by daylight constraints.
