Novel hyperspectral indices, which are the first derivative normalized difference nitrogen index (FD-NDNI) and ratio vegetation (FD-SRNI), were developed to estimate leaf content (LNC) of wheat. The field stress experiments conducted with different water application rates across growing season wheat 190 measurements collected on canopy spectra LNC under various treatments. inversion models constructed based dataset evaluate ability spectral indices LNC. A comparative analysis showed that...

A hybrid inversion method was developed to estimate the leaf chlorophyll content (LCC) and canopy (CCC) of crops. Fifty hyperspectral vegetation indices (VIs), such as photochemical reflectance index (PRI) (CCI), were compared identify appropriate VIs for crop LCC CCC inversion. The models then generated from different modelling methods, including curve-fitting least squares support vector regression (LS-SVR) random forest (RFR) algorithms, by using simulated Compact High Resolution Imaging...

Underground mining activities usually induce large surface displacements thus causing serious safety hazards and potential ecological damage. The capability of conventional Interferometric Synthetic Aperture Radar (InSAR) to monitor tectonic movements, volcanic eruptions city subsidence has been fully demonstrated, but its application is limited because the failure caused by localized with strong spatial gradients. In this paper, a new method presented utilize SAR pixel Offset Tracking (OT)...

Net ecosystem productivity (NEP) plays an important role in understanding function and the global carbon cycle.
