Near Infrared / NDVI
• Near infrared is highly reflected by biomass
• NDVI – biomass index that is normalized to reduce variation in the reflectance in the imagery

Considerations
• Size of the area to be flown, must be scale appropriate
• Transport Canada requirements (SFOC)
• Training of personal to operate
