Imagine investing thousands of dollars into drone flights, only to discover your drone survey maps are distorted, misaligned, or simply unusable for precision work. For many in construction and earthworks, this painful scenario happens more often than it should — and the culprit is frequently overlooked: the camera shutter.
In aerial photogrammetry, especially when mapping sites at speed and altitude, the type of shutter your drone uses can make or break your results. Let’s break down why rolling shutter vs. global shutter is one of the most critical decisions in drone mapping — and how getting it wrong leads to warped, nearly useless maps.
The Camera is the Gatekeeper of Quality
In a recent Propeller Aero webinar, a standout quote summed it up:
“The camera is often the biggest hurdle in creating the imagery earthworks companies need for their day-to-day use.”
At first glance, that might seem surprising. After all, modern drones are packed with smart features, and camera specs are getting better every year. But in aerial mapping, it’s not just about resolution — it’s about the way the image is captured, especially when you’re flying 300 feet up and moving at 15+ mph.
Enter the shutter.
Rolling Shutter vs. Global Shutter: What’s the Difference?
To understand why some drone survey maps look great while others fall apart, you need to know how each shutter works:
Rolling Shutter captures an image line-by-line from top to bottom. That’s fine for still photography. But when your drone is moving, the scene changes as the image is being captured, which can cause skewed buildings, wavy lines, or “jello” effects — exactly what you don’t want in a map.
Global Shutter captures the entire image at once, freezing the frame in time. This eliminates distortions caused by motion, making it the gold standard for photogrammetry.
The difference is subtle to the naked eye but monumental in the data world. When you’re stitching hundreds (or thousands) of images together for a detailed map, rolling shutter distortions introduce inconsistencies that degrade your model’s accuracy.
Real-World Impact on Drone Survey Maps
So what does this mean in the field?
Let’s say you’re documenting a 30-acre site during active construction. You rely on drone data for:
Progress tracking
Volumetric measurements
Site planning
Coordination between teams
If your camera uses a rolling shutter, fast-moving drone flights can introduce warped lines, blurry edges, and uneven ground features into your drone survey maps. The map software may struggle to align images, leading to errors in your final output.
On the other hand, with a global shutter, every image is crisp and aligned — no distortion, no warping. This leads to survey-grade accuracy and true-to-scale models that you can confidently hand off to engineers, PMs, or clients.
In short: Rolling shutters can render your drone maps nearly useless, especially for precision tasks. Global shutters make them impactful and reliable tools.
Shutter Type: Make it a Priority
Whether you’re a drone pilot or a construction manager relying on drone data, the shutter type should be a non-negotiable in your checklist. It’s as critical as choosing the right altitude or overlap settings.
Not all drones offer global shutters, but if accurate mapping is your goal, invest in a system that does. Many high-end mapping drones are built with global shutters for this exact reason.
Elevating Earthworks with Smarter Tools
At Big Falcon Digital, we’ve seen firsthand how global shutter-equipped drones deliver dramatically better drone survey maps. We help construction and manufacturing clients get crystal-clear aerial data that translates directly into more efficient site planning, real-time progress tracking, and reliable as-built documentation .
By focusing on the right technology — including the right shutter — we ensure your drone data works as hard as you do.
Want Better Drone Survey Maps?
If you’re serious about drone mapping, don’t let your camera’s shutter type be an afterthought. Rolling shutters are fine for casual photos, but they’re a liability in aerial mapping. Global shutters, on the other hand, are your best bet for creating high-quality, distortion-free drone survey maps that drive real-world decisions.
