![]() Infrared (IR) lies between the visible and microwave portions of the electromagnetic spectrum. We are unable to see infrared (IR) light with our eyes, but as it grows in intensity and moves down the spectrum we begin to experience it as heat. Learn how Drone Dynamics helps planters to build up NDVI maps to better understand their plants. Thus near infrared imagery is ideal for applications such as agriculture, archaeology and forestry. This band forms part of the complex equation named NDVI, which is used as a baseline for vegetation analysis. The human eye is considerably less sensitive to this area. The band of NIR sitting right next to the visible spectrum is referred to as the “red edge” (NIR, 720nm to 850nm) and is used heavily in agricultural solutions. The near infrared region (NIR, 720nm to 1000nm) is closest in wavelength to the visible region of the electromagnetic spectrum. It forms the backbone of most UAV applications and is fairly easy to process into large maps and mosaics with mainstream programs such as Agisoft Photoscan and Pix4D. Visible imagery is ideal for a wide range of applications including agriculture, archaeology, construction, surveying, mining, forestry, maintenance, marine/maritime and surveillance. This is the light range that our eyes can naturally see. Visible light sensors detect all light that falls in the visible light region of the electromagnetic spectrum.
