What is LiDAR?<\/strong><\/h3>\n

LiDAR (Light Detection and Ranging) is a remote sensing technology that uses laser pulses to measure distances between the sensor and objects on the ground. Based on these measurements, it is possible to generate extremely accurate three-dimensional models of terrain, vegetation, structures, and buildings.<\/p>\n

LiDAR vs. traditional photogrammetry<\/strong><\/h3>\n

While traditional photogrammetry uses overlapping images to reconstruct topography through triangulation, LiDAR directly measures distances, generating high-density point clouds, even in areas with dense vegetation or topographical variations.<\/p>\n\n\n\n\n\n\n

Practical applications in drones<\/strong><\/h3>\n

The integration of LiDAR sensors into long-range drones such as the DJI Matrice 350 RTK<\/a> + Zenmuse L2<\/a> has enabled high-precision topographic surveys to be carried out in record time, especially in:<\/p>\n
