2.2. Airborne
Spatial evaluation of soil environment gives correct mapping of
changeability in agricultural field via Airborne hyperspectral imaging
(Stevens, van Wesemael et al. 2008). It is also useful for data
collection to divide a place in agreement with soil heterogeneity
(Mulder, De Bruin et al. 2011). Airborne set-up sensors exhibit
flexibleness for a specific measurement time window giving power to
choose optimal flight condition and work under an extraordinary-cloud
coverage (Usha and Singh 2013).
