Multispectral imaging

A multispectral sensor is able to record the natural radiation released or reflected by the object or the surrounding areas across the electromagnetic spectrum (visible, infrared and thermal bands).

CGR SpA can employ the MIVIS scanner which records the wavelengths of the natural radiation  in 102 bands, from the visible range to the near, middle, far infrared and thermal bands. All these data are acquired in the same moment for each pixel and with the same field of view to ensure that all the spectral information are coming from the same point above the terrain.

For its spectral characteristics, the MIVIS sensor can be used for different applicative fields where remote sensing techniques are significantly applied, such as Agriculture, Geology, Geomorphology, Botany, etc.

 Applications

Vegetation typical classification

 MIVIS Classificazione tipologie di vegetazioneCharacterization of vegetable coverage (vegetation classification and mapping, spectral libraries processing, sometimes related with field  analysis).Monitoring of vegetation health status  based on biophysics parameters and vegetation indexes.
