Remote sensing of grassland with contaminated soil using the spectral red-edge
No full textIn most cases contaminants are concealed in soil and under vegetation and therefore cannot be measured directly by remote sensing. However, soil contaminants were detectedusing the spectral red-edge to indicate vegetation stress caused by the presence ofthe contaminants. An improved red-edge position (REP) was developed and gave aslight improvement in the predictive capability over existing indices and an effectiveadditional diagnostic indicator of soil contamination was found to be the spatial patternof the REP. Where an area had high levels of hydrocarbon in the soil it also had ahigh level of variation. The indication was that spatial variation of spectral indices(especially the REP) may be more useful than the spectral index value for the detectionand mapping of soil contamination.Field analysis and radiative transfer modelling (using a coupled leaf and canopy model,LIBSAIL) showed the influence of vertical layering in the grassland canopy. The influenceof a vegetated under-storey on the red-edge was found to be greatest whendifferent absorption spectra were present and high within-the-leaf scattering. The formerdefined wavelength positions of features while the later determined if they wereresolvable in a spectrum. This greater understanding of the grassland canopy identifiedthe importance of fully surveying vegetation canopy structure, especially in complex,multi-layered canopies such as those found with contamination. With this understandingof what the red-edge can reveal, remote sensing is an effective tool for the detectionof contamination
