 payload size and weight are critical factors for small unmanned aerial vehicles, UAVs. Digital color infrared photographs were acquired from a single 12 megapixel camera that did not have an internal hot mirror filter and had a red light blocking filter in front of the lens, resulting in near infrared, NIR, green and blue images. We tested the UAV camera system over two variably fertilized fields of winter wheat and found a good correlation between leaf area index and the green normalized difference vegetation index, GNDVI. The low cost and very high spatial resolution associated with the camera UAV system may provide important information for site-specific agriculture. This article was authored by Greg W.
