    I use an Inspire 1 with the X3 camera.  One thing to take into account is the canopy of the crop and if it is not fully closed then you will want to fly at a 15-30 degree angle to the rows, or else the curvature of the lens looking down into the canopy will mess with your stitching.  Also, the sunspots in the camera really messes with stitching so flying directly toward the sun will spread out the sunspot across your image and help in the stitching process.  Two helpful tips that have helped me tremendously.

    We’ve noticed some of the same stitching problems when the sun is high. Crops like wheat seem to disperse the glare, whereas the collective rows of corn seem to act as a big ol’ mirror for high sun. Some folks we talk to have the best stitching when shadows start to get a little long in the early morning or late afternoon; which for RGB imagery is fine. Where NDVI is concerned, maybe the incident light sensor on the newer imaging systems would alleviate(?), but really that’s just speculation.  Thanks for sharing!
