We are proud to present a comparison of satellite NDVI (from the Fruitlook service) and our AgriDrone NDVI for a field of potatoes for the same day. To make this NDVI we created a new spectrum lookup table, to match that of the satellite NDVI. The correspondence is remarkable except that the AgriDrone NDVI is much higher resolution and does not contain ‘edge bias’ errors. To clarify, the lookup table runs from red (low NDVI) to green (mid NDVI) to purple (high NDVI). The potato field is flanked by barley, which having a much higher leaf area shows much higher NDVI. However, within the potato field it is clear the main stressed area is the patch in the lower middle.
