But when using the same technique on a small- er scale (with a drone f lying 70m above the ground), that ratio is said to be correlated with several plant characteristics including biomass, leaf area index and chlorophyll concentration. "Though the (NDVI) ratio is unlikely to be correlated with all these variables at once," Calvet said, "getting one (element) of this infor- mation for all our hybrids with a single drone f light could be interesting; that's why further investigation could be carried out." In the meantime, however, simply counting the gaps in the rows may prove to be particu- larly useful. As applications go, for now, Calvet said, "I think plant counting is still by far the most promising one." TEAMING UP In October 2016, Delair- Tech announced that it had bought Trimble Navigation's drone manufacturing entity Gatewing and allied with Trimble and Germany's microdrones to offer a broader and more complete range of unmanned aircraft solutions. Those solutions now include Gatewing's small fi xed- wing drones and the UX5 multicopter, microdrones' md4- 200, the md Mapping 1000 packages, and Delair-Tech's larger fi xed-wing UAS.
