assessment report have been discussed here. The next step is to compare the results of the image interpretation with measurements taken in the field. This also allows us to calculate approximate carbon values for each class. The next chapter will explain how to collect sample field data required to estimate the above-ground biomass and carbon stock, assign average carbon levels to each category (while noting that the purpose is not to calculate an exact carbon number but rather to differentiate types of land cover through estimated carbon values), and further refine the classification in order to create the land cover map from which the potential HCS forest areas are delineated.
