2. Remote sensing data sources
For renewal as well as monitoring of SOC crossways VNIR-SWIR spectral
span, remote sensing (RS) via various sources gave statistics streams.
Various kinds of sensors (in case of imaging spectroscopy) are set up on
airborne (Castaldi, Chabrillat et al. 2018) or else spaceborne
platforms. As a result, Unmanned Aerial Systems (UASs) are widely used
to perform succeeding generation of hand-sized hyperspectral imagers
(Aldana-Jague, Heckrath et al. 2016). Brief explanation of remote
sensors requirements for SOC estimations are given below:
