When it comes to documenting and analyzing crime scenes or complex environments, drone technology has already transformed how public safety agencies operate. Photogrammetry—using high-resolution drone imagery to build accurate 3D models—has quickly become the go-to solution thanks to its affordability, ease of use, and proven results.
So where does LiDAR fit into this picture? While LiDAR is not yet widely deployed on drones for public safety, it brings unique capabilities that can complement photogrammetry rather than replace it. At MAXSUR, we don’t view one technology as “better” than the other. Instead, each has its strengths—and in many cases, the two can be used together to provide the most complete dataset possible.
LiDAR vs. Photogrammetry: Different Tools for Different Jobs
Photogrammetry
-
Cost-effective and accessible
-
Creates accurate 3D models from high-resolution images
-
Easy to deploy with standard drones and cameras
-
Ideal for large, open areas and detailed visual reconstructions
LiDAR
-
Uses laser scanning to capture millions of points per second
-
Better suited for penetrating vegetation to reveal true terrain details
-
Excels at mapping fine objects like small cables or uniform surfaces
-
Requires a larger, enterprise-class drone due to payload weight
Why Use LiDAR in Public Safety?
For agencies working in environments with dense vegetation, complex infrastructure, or where precise terrain data is needed, LiDAR offers unmatched accuracy. Think of accident reconstruction in wooded areas, powerline inspection for forensic evidence, or capturing the subtle details of a crash scene where every millimeter matters.
By combining LiDAR’s structural accuracy with photogrammetry’s visual detail, investigators can create comprehensive 3D datasets that are both precise and visually rich—an invaluable asset in courtrooms, training environments, and long-term case storage.
The Right Platform for the Job
High-quality LiDAR scanners are heavy, which means they demand drones built to handle enterprise-class payloads. A leading option is the Inspired Flight IF1200 Heavy Lift Hexacopter. This U.S.-made aircraft offers the lift capacity, flight time, and reliability needed to carry advanced LiDAR systems, making it an excellent choice for public safety agencies ready to explore LiDAR applications.
Key Considerations for Agencies
-
Budget vs. Benefit: Photogrammetry is more cost-effective; LiDAR requires larger investments but provides capabilities you can’t get otherwise
-
Mission Profile: Consider terrain, vegetation, and the type of data your investigations demand
-
Integration: Using LiDAR and photogrammetry together can give your team the most accurate and defensible evidence
-
Training & Workflow: Both technologies require planning and expertise to maximize their value in the field
Final Thoughts
LiDAR isn’t here to replace photogrammetry—it’s here to enhance it. Together, these technologies represent the future of aerial scene documentation, giving public safety professionals the ability to capture crime scenes, accidents, and complex environments in ways never before possible.
