Hyperspectral mapping records reflective-emission surface properties in the narrow range of the electromagnetic spectrum. As a result, multi-channel image is being formed, which enables to precisely identify vegetation cover, soil, artificial structures peculiarities and assess their condition. Such image has far greater capabilities than conventional optical image. Any tiny changes and anomalies of object physical properties can be detected by hyperspectral mapping.
Forests characteristics that can be detected:
- Species composition
- Sanitation condition
- Number of trees per unit area
- Tree crown size
- Tree height
- Clearing, dumping, and burnt areas
The system operates remotely from an aircraft or UAV. Impulse is directed to the land surface; reflected from the surface, it returns to the sensor. The system sends more than 200 000 impulses, which enables to continuously scan the entire examined surface.
The laser system principle is that impulses continuously emit from sensor to the objects surface. Impulse interacts with different surfaces. Due to differences in surface physical properties, the nature of impulse reflection may change and vary. Therefore, not only the distance from the sensor to the object is being recorded but also the information about their physical properties.

Individual scanning device
LiBackpack — available and easy portable 3D scanning system.
LiBackpack lets the users of various industries map the information about the examined object quickly and with high accuracy. The processing of data is happening at the very moment of mapping, which allows to see 3D model of points in real time. Software is embedded into the device.
