LiDAR or Photogrammetry – Which one is better?  

Lidar or Photogrammetry

Drones make operations Safer, Efficient, Accurate, Quick, and way more Cost-effective compared to traditional practices. Drones are becoming increasingly popular in Surveying and Mapping, and this adoption can only be attributed to the huge array of benefits that come along with it. Drones allow you to conduct operations with a fraction of the workforce while improving efficiency and accuracy; moreover, drone-powered surveys and mapping are 75%-80% quicker than terrestrial measurement while giving you high precision and improved safety. For surveying and mapping professionals, LiDAR and Photogrammetry data-capturing techniques have been a part of the process. Now the only question that is troubling almost everyone – from amateurs to experienced drone professionals is – ‘Which one is better – Lidar or Photogrammetry?’ and naturally, the next question is – ‘DJI Zenmuse L1 or DJI Zenmuse P1? So let’s get into this dilemma.

DJI Zenmuse L1; LiDAR Survey Made Easy

DJI Zenmuse L1 payload

For a multitude of reasons, DJI’s first Livox LiDAR payload — the Zenmuse L1, is gaining a lot of traction among drone professionals. First of all, the DJI Zenmuse L1 incorporates the powers of both laser and visible light; this payload can simultaneously capture both LiDAR and Photogrammetry data. L1 is well known for capturing ‘accuracy’ by integrating a Livox LiDAR module, a high-accuracy IMU, a survey-grade camera, and additionally, it comes with a 3-axis stabilized gimbal. Well, not just that, there is a lot more to explore on this unparalleled player in the Drone-based solutions!

How DJI Zenmuse L1 Makes Right of Way Surveys Flexible and Practical

Right of Way (ROW) Surveys are tricky but incredibly important to Power & Utilities companies looking to expand their power grid. Especially in areas with dense vegetation and tree growth, in these areas, photogrammetry cannot provide bare ground level elevations. Without a reliable DTM (Digital Terrain Model), the next set of substations and power lines cannot begin. This is where LiDAR comes in. Using drone-powered LiDAR -DJI Zenmuse L1, we were able to survey the modest stretch of land quickly, efficiently and cost-effectively.

Announced late last year, DJI’s first Livox LiDAR payload- the DJI Zenmuse L1- was set to change the game. The L1 comes seamlessly integrated with the DJI M-300 and DJI Terra software, giving you a completely self-sufficient ecosystem. We were excited to test out the new system and took it to the field as soon as we got it; here are our findings.
