DESCRIPTION:Abstract\nSoils are the largest terrestrial carbon pool providi
 ng important ecosystem services\, essential for sustainable land managemen
 t\, agricultural productivity\, and climate regulation. Spaceborne imaging
  spectrometers represent a promising tool for producing up-to-date\, inexp
 ensive and spatially explicit maps. The recent availability of spaceborne 
 imaging spectroscopy sensors provide high signal-to-noise ratio\, such as 
 the EnMAP\, offers new opportunities for detailed and spatially explicit s
 oil assessment.\nThis study investigates the potential of EnMAP hyperspect
 ral imagery for retrieving and mapping key topsoil properties\, with a par
 ticular focus on soil organic carbon (SOC)\, using advanced machine learni
 ng and spectral processing techniques. The analysis conducted across agric
 ultural landscapes in Kopaida region in Central Greece and was supported b
 y an extensive soil sampling campaign designed to capture the spatial vari
 ability of soil conditions within the study area.\nBare soil spectra were 
 extracted from EnMAP imagery\, and the effects of spectral transformations
  and feature selection on model performance were assessed. Random Forest (
 RF) models were trained based on different spectral transformations and fe
 ature-selection methods\, and their impacts on predictive performance were
  compared to derive a robust modelling workflow. The SOC results showed st
 rong performance at the laboratory scale. Results demonstrated the potenti
 al of EnMAP hyperspectral observations for operational soil monitoring and
  support the development of scalable methodologies for regional soil monit
 oring and digital soil mapping. Overall\, the generated soil maps revealed
  substantial spatial variability across the study area\, highlighting the 
 influence of local environmental factors on soil distribution patterns.
