Multi-Round Monitoring and Time Windows
In some industries—like large-scale construction projects—monitoring a site just once isn’t enough. You might need multiple visits to track changes:
- Minimum and Maximum Intervals: For instance, if a site must be checked every two weeks, but not more than four weeks apart, you must schedule flights carefully.
- Progress Documentation: Regular aerial captures help managers compare “before” and “after” images to identify potential hazards, structural shifts, or project milestones.
Charging and Battery Considerations
- Battery Endurance: Most UAVs can fly for 20–50 minutes, depending on factors like payload and wind conditions. Longer flights require either battery swaps or mid-mission charging, which influences route planning.
- Charging Stations: Large sites might have multiple charging stations so that the drone can “hop” from one station to another, reducing downtime.
- Power Management Strategy: Tools for route optimization factor in the flight time needed between each waypoint and when the drone must land to recharge.
No-Fly Zones and Route Accessibility
Some areas may be restricted for drone flights due to safety or regulatory reasons:
- Obstacles and Structures: Buildings, cranes, or tall trees may require flight path adjustments.
- Geofencing: Certain software prevents a drone from entering regulated airspace. Operators must plan routes that respect these boundaries.
- Detours: If direct flight paths are blocked, the drone’s route may become longer, adding time and battery consumption to the inspection schedule.
Understanding these aspects ensures that a UAV-based inspection proceeds smoothly, on time, and within budget.
