Environmental Conditions
Lighting
Imagery should be captured between the time of 2 hours after sunrise and 2 hours before sunset. Consistent lighting conditions required for best results, including avoidance of hard shadows cast over the field which cause bright spots and dark spots in the dataset.Wind
Wind conditions should be within the specified limits of the aircraft or system being used to carry the imaging sensor.Precipitation
There should be no active precipitation during imagery capture.Deliverables

Tree NDVI (87004-00)
Description
Normal Difference Vegetation Index (NDVI) is a commonly used indicator of Crop Health that is useful in differentiating a healthy tree from a stressed tree or sensing crop or from bare soil. NDVI uses imagery containing Red and Near-Infrared spectral bands. While NDVI does not necessarily diagnose the source of tree stress, it is a useful metric to quantify variability and location of relative strong and poor tree performance.Deliverable List

Tree NDRE (87005-00)
Description
Normal Difference Red-Edge Index (NDRE) is a derivate of NDVI using the Red-Edge spectral band rather than the Near-Infrared spectral band. NDRE uses imagery containing Red-Edge and Near-Infrared spectral bands, and is particularly sensitive to crop nutrient stress, including crop nitrogen status. While NDRE does not necessarily diagnose the source of tree stress, it is a useful metric to quantify variability and location of relative strong and poor tree performance.Deliverable List
