The Challenge: Documenting Active Coastal Construction
Coastal construction sites present unique documentation challenges that inland projects never encounter. Salt spray, unpredictable wind gusts, and rapidly shifting light conditions demand equipment that adapts instantly.
I recently documented a 12-story beachfront resort development in Southern California. The project manager needed weekly progress documentation for investors, insurance records, and regulatory compliance. Standard drone footage wouldn't cut it—they needed cinema-quality captures that showed precise construction details while handling the harsh coastal environment.
The Mavic 4 Pro became my primary tool for this three-month assignment. Here's exactly how I configured and operated it for professional results.
Pre-Flight Protocol for Coastal Environments
Sensor Calibration in Salt Air
Before each flight session, I run a complete sensor diagnostic. The Mavic 4 Pro's omnidirectional obstacle avoidance system uses 8 wide-angle vision sensors plus 2 fisheye sensors for complete environmental awareness.
Salt crystallization on sensor surfaces degrades detection accuracy. My pre-flight checklist includes:
- Microfiber wipe of all sensor lenses with distilled water
- Gimbal calibration to compensate for any salt buildup on motors
- IMU verification after transport to coastal locations
- Battery contact cleaning to prevent corrosion-related power fluctuations
Pro Tip: Store your Mavic 4 Pro in a sealed case with silica gel packets between coastal flights. This reduces salt moisture absorption by approximately 60% and prevents internal corrosion.
Wind Assessment and Flight Planning
Coastal winds rarely stay consistent. The Mavic 4 Pro handles sustained winds up to 12 m/s and gusts to 15 m/s, but construction site documentation requires stability beyond mere survival.
I use a three-tier wind protocol:
| Wind Speed | Flight Approach | Recommended Settings |
|---|---|---|
| 0-6 m/s | Full creative freedom | Normal mode, all QuickShots available |
| 6-10 m/s | Modified patterns | Sport mode for positioning, Cine mode for capture |
| 10-12 m/s | Essential shots only | Manual exposure, increased shutter speed |
When Weather Changed Everything
Three weeks into the resort project, I launched for a routine morning capture session. Conditions read 4 m/s winds, clear skies, perfect visibility. Twenty minutes into the flight, everything shifted.
A marine layer rolled in faster than any forecast predicted. Wind speed jumped to 9 m/s with gusts hitting 13 m/s. Visibility dropped from unlimited to approximately 800 meters in under four minutes.
The Mavic 4 Pro's response impressed me. The obstacle avoidance system immediately detected the construction crane that had become partially obscured by fog. Rather than relying solely on my visual line of sight, the drone's sensors identified the structure at 45 meters and adjusted my planned flight path automatically.
ActiveTrack maintained focus on the concrete pour happening on level seven, even as I repositioned the drone to compensate for wind drift. The subject tracking algorithm predicted equipment movement and kept framing consistent despite my control inputs fighting the gusts.
Expert Insight: When conditions deteriorate rapidly, resist the urge to immediately return home. The Mavic 4 Pro's sensors often provide better situational awareness than your eyes in reduced visibility. Trust the obstacle avoidance while you execute a controlled, deliberate return rather than a panicked rush.
I captured 47 usable frames during that weather transition—footage the project manager later called the most dramatic documentation of the entire build. The fog lifting over the partially completed structure became their primary marketing asset.
D-Log Configuration for Construction Documentation
Coastal construction sites present extreme dynamic range challenges. Bright sand reflects intense sunlight while scaffolding and interior spaces fall into deep shadow. Standard color profiles clip highlights or crush shadows—often both.
The Mavic 4 Pro's D-Log M color profile captures approximately 14.5 stops of dynamic range. This preserves recoverable detail across the entire exposure spectrum.
My D-Log Settings for Coastal Construction
- ISO: Base 100 whenever possible, never exceeding 400 for documentation work
- Shutter Speed: Double the frame rate minimum (1/50 for 24fps, 1/60 for 30fps)
- Aperture: f/4 to f/5.6 for optimal sharpness across the 1-inch CMOS sensor
- White Balance: Manual 5600K for consistency across clips
Color Grading Workflow
D-Log footage requires post-processing. I apply a base correction LUT, then adjust:
- Lift shadows by 15-20% to reveal scaffolding detail
- Reduce highlights by 10-15% to recover sky texture
- Add 5-8% saturation to compensate for D-Log's flat profile
- Apply subtle orange/teal grade to enhance construction equipment visibility
Hyperlapse for Progress Documentation
Weekly progress reports benefit enormously from Hyperlapse sequences. The Mavic 4 Pro offers four Hyperlapse modes, but construction documentation primarily uses two:
Waypoint Hyperlapse
I establish 5-7 waypoints around the construction perimeter, creating a consistent orbital path. Each week, I fly the identical route, capturing 300+ frames per sequence.
The resulting Hyperlapses show construction progress from identical perspectives, making week-over-week comparisons immediately apparent to stakeholders.
Free Hyperlapse
For specific detail documentation—concrete pours, crane operations, material deliveries—Free Hyperlapse allows manual control while the drone handles interval timing and stabilization.
Key settings for construction Hyperlapse:
- Interval: 2 seconds for slow-moving construction activity
- Duration: Minimum 10 minutes of real-time capture for 15 seconds of final footage
- Resolution: 4K for maximum crop flexibility in post-production
QuickShots That Actually Work on Construction Sites
Not every QuickShot mode suits construction documentation. After extensive testing, three modes consistently deliver professional results:
Orbit
Circling completed structural elements showcases scale and context. I typically set orbit radius at 30-50 meters with speed at 3 m/s for smooth, professional movement.
Rocket
Vertical reveals work exceptionally well for multi-story progress documentation. Starting at ground level and ascending to full building height creates dramatic before/after comparisons.
Helix
Combining orbital movement with altitude gain captures both horizontal and vertical construction progress simultaneously. This mode requires clear airspace above the structure.

Common Mistakes to Avoid
Ignoring salt accumulation between flights. Even invisible salt deposits degrade sensor accuracy and motor performance. Clean thoroughly after every coastal session.
Flying in D-Log without understanding post-processing. Raw D-Log footage looks flat and unusable. Budget time for color correction or your deliverables will disappoint clients.
Trusting weather apps over on-site observation. Coastal microclimates shift faster than forecasts update. Check actual conditions immediately before launch.
Positioning too close to active construction. Obstacle avoidance works brilliantly, but crane swings and material hoists move unpredictably. Maintain minimum 20-meter clearance from active equipment.
Neglecting battery temperature in marine environments. Cold ocean air reduces battery performance by 15-25%. Keep batteries warm until launch and monitor voltage carefully.
Frequently Asked Questions
How does the Mavic 4 Pro handle sudden wind gusts during coastal flights?
The drone's flight controller makes approximately 2,000 adjustments per second to maintain position and stability. When gusts hit, the system compensates almost instantaneously, though you'll notice slight position drift in extreme conditions. The key is allowing the drone to stabilize rather than fighting it with aggressive stick inputs.
Can ActiveTrack follow construction vehicles through complex site layouts?
ActiveTrack 6.0 uses predictive algorithms that anticipate subject movement based on trajectory analysis. For construction vehicles following predictable paths, tracking accuracy exceeds 95%. However, vehicles making sudden direction changes may briefly lose lock. The system typically reacquires within 2-3 seconds.
What's the best approach for documenting both interior and exterior construction progress in a single flight?
Start with exterior establishing shots in full sunlight, then transition to interior spaces. The Mavic 4 Pro's auto-exposure handles the transition smoothly, but for professional results, land and manually adjust settings before entering enclosed spaces. Interior construction typically requires ISO 400-800 and wider apertures.
