What is the LiDAR and how it works?
LiDAR for Light Detection and Ranging, it is an assembly of different modules capable of emitting a light (laser) and measuring its variations when it encounters an obstacle. These variations are transcribed into points that can be classified and represent at the end a point cloud that will be a 3D representation of our environment.
To perform the mapping, we will grid the area with our drones, above a defined perimeter. During the flight, the laser raises more than 100,000 points per second and is able to pierce the vegetation to reach the ground. Our drones and LiDAR are synchronized with an RTK GNSS Base Station who sends the GPS correction in real-time to keep a centimetric accuracy. In some cases, we process the GPS correction in post-flight using PPK technology.
With this method, we can generate Digital Elevation Model (DEM) and also Digital Terrain Model (DTM) because the laser and our software are able to classify the readings to make them appear only in some object classes in post-processing, like trees or buildings for example.
A Digital Surface Model (DSM) and Digital Terrain Model (DTM) are both types of digital elevation models (DEMs), which are representations of the Earth’s surface using elevation data. They are used in various applications, such as remote sensing, GIS, cartography, and environmental and urban planning. However, there are some key differences between the two models:
Digital Surface Model (DSM): A DSM represents the elevation of the Earth’s surface, including both natural and man-made features. It includes the heights of buildings, trees, and other objects on the terrain. DSMs are typically created from remote sensing data, such as aerial photographs, satellite imagery, or LiDAR (Light Detection and Ranging). They can be used in applications like urban planning, 3D modeling, telecommunications, and line-of-sight analysis.
Digital Terrain Model (DTM): A DTM, on the other hand, represents the bare ground elevation, removing any above-ground objects like buildings and vegetation. It provides a more accurate representation of the Earth’s surface, focusing on the topography and terrain features such as hills, valleys, and slopes. DTMs are often created by processing DSMs to remove the above-ground objects and interpolate the bare ground elevation. They are used for applications like hydrological modeling, flood risk assessment, land use planning, and geological analysis.
From these point clouds, we can also extract other data, such as contour lines and we can realize orthomosaic plans, thanks to the photos captured during the flight. These data can be integrated into your professional software (GIS and Autocad for example)
