Airborne LiDAR scanning is an active remote sensing technology, which is capable to gather very precise data over a large area fast and it is applicable to measure on those areas where traditional on-field geodesic surveys can be realized with great efforts and resource needs.
Orthophotos look just like regular ones at first glance, but it lacks the geometrical distortion that regular photos are subject to. They are vectored photographs, which allows us to make precise calibrations and measurements based on them.
Images assessed through aerial hyperspectral technology contain information in spectrum that is invisible to the human eye.
The technological advances of the past decade accelerated the improvement of remote controlled and automated tools. Perhaps, the most intensive progress and the greatest attention was focused on the development of UAVs (Unmanned Aerial Vehicles) and their applications.
