Hyperspectral mapping is a non-invasive remote sensing technique (i.e. the observation of phenomena and features from a distance) that combines standard, conventional imaging with spectroscopy. Although originally developed for military and space use, it is now used, among other things, in crops and especially in viticulture, allowing farmers to have a more detailed picture of the condition and health of their crops.
To capture hyperspectral images, satellites or drones equipped with special cameras are used. Each consists of a number of spectral bands: the more these bands, the greater the amount of information included. Hyperspectral technology is a real revolution in the field, especially if one compares it with the immediately preceding technology: when multispectral mapping could offer five to seven such bands, in hyperspectral their number exceeds 40!
The way hyperspectral mapping works is based on the reflection of sunlight on the surface of plants. Crops, depending on their condition (from hydration levels and soil quality, to possible diseases or pests that may have appeared) reflect light differently, as any change affects their physiology and consequently their reflective properties.
Therefore, having the ability to identify a wide range of chemical and biological characteristics, hyperspectral mapping is able to inform winegrowers about possible water shortages or excessive moisture, poor soil quality or even diseases in their early stages. The above data leads to so-called precision agriculture, allowing growers to focus on the real needs of their crops (fertilizers, irrigation, etc.), improving their production while reducing costs.
Oenolytics’ integrated solutions move in exactly this direction, providing remote observation capabilities using hyperspectral mapping technology at affordable prices and through an easy-to-use interface, offering winegrowers the optimal prevention for their crops.
