Orange Grove Study
July 21, 2015

During this survey the sun was going in and out from behind the clouds. You'll notice that the Visible Light image shows some of the trees shaded abnormally due to this change in sunlight. The NDVI images though were not affected by the clouds. All stitching was completed with Pix4D Pro after the images were geo-tagged in post.

The stitching was not perfect due to the increased speed and low altitude. Our recommendation is 8kmh (5mph) per 20m (65ft) altitude or slower.
