3-4-1- Preprocessing and processing of the image
After preprocessing the image through the removal haze, the appropriate processes were done (see the methodology). The results of GWR showed that amongst different spectral variables (i.e., band analysis, vegetation indices, and texture analysis) difference between Excess Red Plant Index (ExR) and Excess Green Plant Index (ExG), which was indicated by ΔExGR had a significant correlation with the annual carbon sequestration. Figure 2 shows the result of applying the ΔExGR index on worldview image to extract tree canopy.
