The cross-section displays a 30mm slice of the model, and displays data variance within that slice. In this scenario, this elevation view shows the minimal elevation variance in the models created from the L1, but it is worth noting that sharp elevation changes in the 30mm slice could be responsible for elevation variance rather than noise. Deep Insights From LiDAR Data How accurate is a drone survey? It's an important and frequently-asked question when it comes to aerial mapping.

And yet, compared to aerial photogrammetry, the adoption of commercial drone LiDAR technology has been conspicuously slow. Blame it on the paucity of lightweight yet highly functional and inexpensive airborne LiDAR systems or pin it on the complexities of post-processing and classifying the super dense data, the fact remains that aerial LiDAR technology is yet to have its day in the sun.TerraSolid offers a comprehensive suit of tools to conduct classification and convert the information to the British coordinate system, also known as OSGB36. DJI M600 has 2 D-RTK GNSS antennas receiving the GPS L1/L2 and GLONASS F1/F2 constellations, which are resistant to strong magnetic interference and allow centimeter-level positioning. Measured with video transmission control system operating in Control mode in an unobstructed environment free of interference with FCC compliance. Image captured by the Phantom 4 RTK and processed at high resolution through high-performance workstations. Equipped with a mechanical shutter and the all-new TimeSync 2.0 system, which synchronizes time across modules at the microsecond level, the Zenmuse P1 lets users capture centimeter-accurate data combined with real-time position and orientation compensation technology.

Image captured by the Phantom 4 RTK and processed at high resolution through three high-performance worker devices. The inertial measurement unit (IMU) measures a drone’s real-time 3-axis acceleration and angular velocity, thereby calculating the aircraft’s speed, position, and altitude angle. A high-accuracy IMU is pivotal for quality LiDAR data collection because, without it, your point cloud would be nothing but an arbitrary collection of points.This is something we would struggle to achieve without the overview obtained from the drone LiDAR survey," said Darren.
