We have been using them for 3 years now, we have a fixed wing ebee with a NIR and colour camera. We have been using it to do vr dribble band N in wheat, and corn, and VR fungicide in canola by creating NDVI images. We have also done bare earth imagery to help define our maps for VR irrigation and fertility, as well as pivot calibrations using colour images as areas that are getting less or more water show up quickly in the crop. The main thing to fly large fields is you cannot use a copter type drone as they don't have the battery life to make enough passes and take enough images to make a detailed image. There are some out there that claim they can do it in less passes but even in there demo images on their website I can see poor imagery that I would never use for any kind of crop application cause by not enough overlap of the images.

What we can do will gain more and more every year with more sensors, there are thermal sensors out now that would be great for seeing stress in a crop from insect or disease pressure before it is visible to the naked eye. As well there are multi-spec cameras coming out that will allow us to get both a colour and NIR image in the same flight which we can make a true NDVI image. Some are also working on fine tuning cameras to pick up disease infection before it shows visible symptoms.
