Key Sensor Types

Agricultural remote sensing is nott a one-size- fits- all approach. Several sensor type are common used, each phased to different applications:

  • Xi1; Xi1; FLT: 0 X3; Xi3; Multispectral sensors: Xi1; Xi1; FLT: 1 XI3; Xi3; Capture data in several disrate spectral bands, typically included ding red, green, near-infrared (NIR), and sometimes red- edge. Normalized Difference ce ce Vegetation Index (NDVI) is a classic vestiation index derived from such data, widelly used to assess crop vigor.
