Spectral signature of vegitation
The shape of the reflectance spectrum can be used for identification of vegetation type. For example, the reflectance spectra of d…
Spectral Reflectance Signature of vegetation ( in remote sensing)
Vegetation has a unique spectral signature that enables it to be distinguished readily from other types of land cover in an optica…
Spectral Reflectance Signature 2
The reflectance of clear water is generally low. However, the reflectance is maximum at the blue end of the spectrum and decreases…
Spectral Reflectance Signature ( Remote sensing)
When solar radiation hits a target surface, it may be transmitted, absorbed or reflected. Different materials reflect and absorb d…

Landsat satellite (remote sensing)
The sensors aboard the Landsat satellite measures reflected radiation in seven spectral bands from the visible through the thermal…
spectral sensitivity ( remote sensing)
This spectral sensitivity makes it suitable for measuring vegetative condition and because the satellite passes overhead twice a d…
Infrared images (remote sensing)
Satellite remote sensing is becoming more readily available for use in precision agriculture. The Landsat and the NOAA polar-orbit…
Infrared images (remote sensing)
If the stress continues it could be a sign of insect infestation. The farmer still has to conduct in-fieldassessment to identify t…
