Product Overview
Description
Field Scale Crop Health provides measurements of vegetation indices including Normalized Difference Vegetation Index (NDVI), Normalized Difference Red Edge Index (NDRE), or Visible Atmospherically Resistant Index (VARI).

Environmental Conditions
Lighting
Imagery should be captured between the time of 3 hours after sunrise and 3 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

Visualized Layers
Composite, Single-band, and Index visualized layers are dynamically rendered in FieldAgent. Composite layers include Color Infrared (NIR, R, G) and Natural Color (R, G, B). Single band layers include Blue (B), Green (G), Red (R), Red Edge (RE), Near Infrared (NIR), Long Wave Infrared (LWIR). Index layers include Normalized Difference Vegetation Index (NDVI), Normalized Difference Red Edge Index (NDRE), Green Normalized Difference Vegetation Index (GNDVI), Green Leaf Index (GLI), Chlorophyll Index Red Edge (CIRE), Chlorophyll Index Green (CIG), and Normalized Difference Water Index (NDWI). Multispectral imagery that does not include the specific band(s) needed to render a given layer will not be visualized.
