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.
