Product Overview
Description
Permanent Crop Multispectral and/or Thermal Tree Health provides tree-level measurements of Blue (B), Green (G), Red (R), Red-Edge (RE), Near-Infrared (NIR), and Long-Wave Infrared (LWIR) spectral bands and derivate vegetation indices. This product utilizes precision-aligned orthomosaics derived from high-resolution 6-band multispectral imagery. Specific deliverables for this product are sensor dependent. Multispectral imagery that does not include the particular 6-band configuration of B, G, R, RE, NIR, and LWIR will include only a subset of deliverables.Recommended Use Cases

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

Tree Multispectral and Thermal (87011-00)
Description
Tree Multispectral and Thermal includes a standard set of 8 vegetation indices and single band measurements derived from 6-band multispectral imagery containing Blue (B), Green (G), Red (R), Red-Edge (RE), Near-Infrared (NIR), and Long-Wave Infrared (LWIR) spectral bands. This includes 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). These vegetation indices and the underlying radiometrically calibrated or uncalibrated band measurement data have a wide range of applications. Multispectral imagery that does not include the particular 6-band configuration of B, G, R, RE, NIR, and LWIR will include only a subset of deliverables. Units for B, G, R, RE, and NIR bands are provided as Reflectance (%) if calibrated, or as Digital Number (#) if not calibrated. Units for LWIR band are provided as Temperature (deg C). Vegetation indices are provided as unitless values (#).Deliverable List
