Understanding Photogrammetry—And How Drones Have Changed Everything
Photogrammetry is the science of making measurements from photographs. This technique uses photos to create maps or 3D models of real-world objects or scenes, capturing intricate details by processing multiple overlapping photographs taken from different angles.
In the last ten years, drone technology has radically changed photogrammetry.
Why? Put simply, drones have made it much easier and more cost-effective to collect aerial imagery, especially in hard-to-reach areas or large areas.

This accessibility has expanded the application of photogrammetry across a range of fields, including agriculture, archaeology, construction, and environmental monitoring, empowering professionals to obtain accurate, actionable data without the substantial costs and logistical challenges previously associated with aerial surveying.
Moreover, the integration of advanced sensors and cameras on drones has continued to enhance the precision and quality of data collected. Today, drones are an indispensable tools in the photogrammetry toolkit.
A Note on Drone Photogrammetry vs. LiDAR for 3D Mapping
3D maps can be made using either photogrammetry or LiDAR data. This can be confusing, because sometimes when people are talking about 3D models made with drone data they’re talking about LiDAR, and sometimes they’re talking about photogrammetry.
Keep reading for a quick overview on the key differences, and how to navigate choosing between the two.
Drone Photogrammetry
Photogrammetry uses images captured by drones to create 3D models and maps. It’s highly effective in well-lit conditions where high-resolution visual detail is required. The technology is more cost-effective compared to LiDAR and is accessible for projects with smaller budgets.
- Advantages. Cost-efficient, provides high-resolution imagery, good for mapping in visible light conditions.
- Limitations. Less effective in low light or where obstructions prevent clear imagery, such as in dense forests.
LiDAR with Drones
LiDAR technology uses laser light to scan the ground and objects to create detailed 3D models. It excels in areas where photogrammetry might struggle, such as low-light environments or when mapping complex geometries like forests, where foliage can obstruct visible light imaging.
- Advantages. Highly accurate in diverse conditions, can penetrate obstacles like foliage, and is effective in both day and night.
- Limitations. Historically more expensive than photogrammetry, though costs have been decreasing, making it more accessible and popular.
So Which Should You Choose?
Despite the rise in popularity of LiDAR due to its increased accessibility and reduced cost, photogrammetry remains a viable and widely used method for creating 3D models, especially in projects where visual detail and color are important.
The choice between drone photogrammetry and LiDAR will depend on the specific requirements of your 3D mapping project, including your budget, terrain complexity, and the level of detail required in the final output.

In almost any circumstance, doing drone photogrammetry will qualify as commercial drone operation under current FAA guidelines. Even if you’re not getting paid, the FAA views any activity done for trade or barter as a commercial drone operation.
Here’s a quick overview of what you need to do to operate drones commercially in the U.S.
1. Understand and Follow the Part 107 Rules
The FAA’s Part 107 rules cover all commercial drone operations in the U.S.
- Remote Pilot Certificate. Obtain a Remote Pilot Certificate by passing the FAA Part 107 Knowledge Test.
- Drone registration. Register any drone weighing more than 0.55 pounds with the FAA before flying commercially.
- Visual Line-of-Sight (VLOS). Always keep the drone within visual line-of-sight and use visual observers as necessary.
- Daylight operations. Operate the drone only during daylight or civil twilight (30 minutes before sunrise to 30 minutes after sunset) with appropriate anti-collision lighting.
- Maximum altitude and speed. Do not fly above 400 feet above ground level (AGL) or faster than 100 mph.
- Yield right of way. Always yield the right of way to manned aircraft and avoid flying near other aircraft.
- No flights over people. Do not fly directly over people unless they are directly participating in the operation or located under a covered structure that can protect them from a falling drone.
It’s crucial for drone operators to familiarize themselves with these rules to avoid penalties and ensure the safety of airspace. Special attention should be paid to local laws which may further restrict drone usage in certain areas or during specific events.

- Conduct a pre-flight safety check. Before taking off, perform a thorough pre-flight check. This includes inspecting the drone for any physical damage, checking the propellers, ensuring all electronics function correctly, and verifying GPS signal strength and connectivity.
Flying the Mission
- Launching the drone. Find a clear area for takeoff and ensure the home point is well recorded for the return-to-home feature. Take off and allow the drone to stabilize at an initial altitude.
- Begin mission execution. Initiate the pre-planned flight path. Monitor the drone’s progress constantly, keeping an eye on battery levels, signal strength, and camera settings.
- Data capture. As the drone follows the flight path, ensure it captures images at the set intervals. Monitor the image quality and coverage through the controller’s display.
- Monitor environmental conditions. Keep a close watch on changing weather conditions that might affect the flight, such as sudden winds or rain.
- Completing the flight. Once the area has been fully covered, guide the drone back to the landing spot. Perform a safe landing and immediately turn off the drone and camera.
- Post-flight procedures. Download the captured data and check the image quality and coverage. Conduct post-flight equipment checks and store everything securely.
