In the context of this class we had to work with LiDAR data in eCognition software. We executed the vegetation extraction process by setting new rulesets in eCognition software. We generated masks which will show all vegetation.
LiDAR stands for Light Detection and Ranging, it is similar to RADAR, but it is using infrared spectrum, LiDAR is active sensor, because it is not using solar energy to see the reflectance. LiDAR is actually a platform, it is not a single sensor, it is the combination of other sensors. It has a positional part, inertial technology, laser scanner and digital imagery. The last one can be added, but it is not necessary.
