Aerial surveying with LIDAR

Aerial surveying with LIDAR , for its acronym (Light Detection and Ranging), is an advanced technology that allows obtaining detailed and accurate terrain data from the air. This technique uses pulses of laser light to measure the distance between the sensor and the object, providing three-dimensional information about the environment with high resolution and accuracy .

Aerial surveying with LIDAR is used in a wide range of applications, from mapping and 
civil engineering to agriculture and natural disaster management . With this technology, it is possible to generate digital models of the terrain, analyze soil morphology, identify changes in the landscape and calculate land volumes, among many other functions.

Thanks to aerial surveying with LIDAR, we can carry out surveying work quickly , efficiently and safely , reducing costs and minimizing risks. In addition, this technology allows us to obtain detailed data in areas that are difficult to access or large, making it an indispensable tool in many jobs.

At ESTOP we have the DJI MATRICE 350RTK drone with the Zenmuse L2 LIDAR sensor

1. This sensor offers greater precision in detecting obstacles and creating maps compared to other obstacle avoidance sensors.
2. Greater range: Said LiDAR has a detection range of up to 40 meters, which provides greater long-distance obstacle detection capacity.
3. Improves Safety: By providing more accurate obstacle detection, LiDAR L2 helps avoid collisions and increases safety for both the drone and nearby people and objects.
4. Greater Reliability: Using next-generation LiDAR technology, this sensor offers greater reliability in obstacle detection, improving confidence in performing flight missions. L2 not only detects smaller objects with a higher level of detail, it can also penetrate denser vegetation and generate more accurate Digital Elevation Models (DEM).
5. Supports 5 returns: In areas of heavy vegetation, the L2 can capture more points of soil under the leaves.
6. High-level precision: By combining GNSS and a self-developed high-precision IMU, this solution achieves 4cm vertical accuracy and 5cm horizontal accuracy
7. Effective point cloud rate: 240,000 pts./s. In single and multiple return modes, the L2 can achieve a point cloud emission rate of 240,000 points per second.
