uav aerial surveys

Webber Surveying has been utilizing drones for surveying and mapping purposes since 2018. We now have drones for photogrammetry and lidar scanning devices which are capable of sub 0.1 foot accuracies. Using powerful photogrammetry software overlapping aerial images can be processed into accurate 3D models, orthomosaics, and point clouds. Using lidar scanning devices we can now penetrate the forest canopy to capture the forest floor. Lidar scanning can also accurately locate power lines, utility poles, towers, guy wires, street signs, and other thin and/or non-textured surfaces difficult with just photogrammetry. All aerial projects will include ground targets and check shots surveyed accurately to verify horizontal and vertical accuracy of the final product.

DJI Matrice 350 RTK with the Zenmuse L2 LiDAR scanner

The DJI Matrice 350 RTK with the Zenmuse L2 LiDAR scanner is a professional-grade aerial mapping solution built for precision and efficiency.

The Zenmuse L2 LiDAR scanner elevates this setup with a high-precision LiDAR module, a 4/3 CMOS RGB mapping camera, and a high-accuracy IMU on a 3-axis stabilized gimbal.

Paired with DJI Terra software, it’s a complete solution for geospatial data collection, perfect for surveying, construction, and infrastructure projects.

DJI Phantom 4 RTK

The DJI Phantom 4 RTK has a dual frequency GNSS receiver and a 20M camera. It is capable of capturing hundreds of high resolution aerial photographs in a single flight. Those photographs are fed into digital photogrammetry software such as our Agisoft MetaShape and processed into 3D models or high resolution aerial orthomosaics which can be very accurately georeferenced and be used seamlessly with existing field surveys.
