UAV Photogrammetry Survey &
Lidar Drone Mapping

What Is UAV Photogrammetry & Lidar Services

UAV (unmanned aerial vehicle) photogrammetry is a method of using aerial photographs taken by a UAV to create maps and other geospatial products. The process involves using specialized software to analyze the photographs and extract information about the location, orientation, and shape of features in the images. This information is then used to create accurate representations of the features on a map.

UAV LiDAR (light detection and ranging) is a method of using a laser ranging sensor mounted on a UAV to create maps with high-resolution elevation data. The LiDAR sensor emits a laser beam and measures the time it takes for the beam to bounce back after it hits the ground. By analyzing the time delay and the angle of the laser beam, the LiDAR sensor can determine the distance between the UAV and the ground, which can be used to create detailed maps of the terrain. Both UAV photogrammetry mapping and LiDAR drones can be used to create accurate, high-resolution maps and other geospatial products for a variety of applications, including land use planning, engineering, and environmental management.
