MULTISPECTRAL

Multispectral cameras are capable of capturing several light spectra simultaneously. From multispectral images, we can calculate different vegetation indices that indicate the health of the vegetation. These indices are commonly used in precision agriculture to optimize crops.

The indicators give us information about the hydration of the plants, the amount of chlorophyll it activates, and the amount of leaf it has, among other information. Possibly the most common and well-known index is the NDVI (normalized difference vegetation index) by means of which we can measure the metabolic state of the plant. Other indices that can be obtained are SAVI, RG, GVI, GNVDI, RVI, among others.

Octocam-maps carries out different vegetative control projects throughout Spain, monitoring the vegetative health of different wetlands.

For this work, we have a state-of-the-art multispectral camera. It is the Micasense Rededge-P with Skyport kit for our Matrice 300 RTK aerial platform. It has 6 different high-resolution multispectral band cameras and can generate both RGB and different combinations of multispectral images. Thanks to the DJI kit, we can geo-reference the images more accurately, with the use of the RTK base linked to the drone.
