Frequently Asked Question
What is the difference between Single Sensor or Converted Consumer Cameras and Multispectral Sensors?
With the proper equipment, NDVI imagery can be collected with a drone and processed to create map overlays that can give a wealth of potentially cost saving information.
"Proper Equipment" is the key phrase here. There is no shortage of companies who are willing to sell users "Ag" or "NDVI" cameras that are nothing more than hacked cameras with the IR blocking filters removed and a blue filter installed. We will not mention any particular model here because they are all very misleading in the capabilities and accuracy. Accurate NDVI data processing requires the capability to calibrate the camera and the imagery to ensure that the ratios of near infrared light and visible light throughputs are known and can be appropriately scaled. Hacked consumer cameras cannot do this and a scientific-grade camera must be used for accurate results.
This is why we decided to use the MicaSense™ RedEdge® MultiSpectral Sensor.
MicaSense™ have been successfully supplying Agricultual Sensors like the RedEdge® for a number of years and are considered the Industry Standard.
The smaller and newer sibling to the MicaSense™ RedEdge®, the Parrot SEQUOIA, also provides excellent spectral imagery in the size of a GoPro camera.
However, the RedEdge® provides 5 discrete bands (R, G, B, RE, NIR) at a higher quality and interfaces better with ATLAS processing.
Our aim is to provide reliable and proven data to our clients.
