Mr. Florian Chazottier from ENEO France, visited the OchraVine Control Project experimental vineyards in Nemea, Greece during his secondment in Agricultural University of Athens.
During his visit he collected NDVI (Normalized Difference Vegetation Index) and NDRE (Normalized Difference Red Edge Index) data, by using two different georeferenced spectro sensors (Crop Circle and Spectro Sense). With these sensors he had the opportunity to measure NDVI on the row (Crop circle sensor) using artificial light and above the canopy (Spectro Sense) using sunlight. In order to be more efficient, in the flat area the sensors were placed on a motorbike. At the same time a drone with a multispectral camera, took pictures of the vineyard to evaluate water stress.
