摘要

Although above ground biomass (AGB) inventory provides critical information for sustainable ecosystem management, credible metrics assaying AGB remain a significant challenge. Projecting AGB dynamics, can be enhanced by understanding technological processes and products, thereby isolating the “myths from reality”. Generally, “myths” tacitly presuppose map aptness, whereas “reality” create awareness to proceed with caution by exhibiting imperfections that not only enhance knowledge but create new opportunities for innovation on remedial strategies. Other than data issues (i.e., complexity, heterogeneity, scarcity, accessibility), factors influencing scientific integrity and accuracy in AGB quantification include efficacy of measurement tools, robustness of algorithm, and systemic error in generalized map products smoothened after mosaicking. Here, AGB quantification at variable scales particularly for heterogeneous landscapes are explicated, and limitations of generalization exposed. Consideration is given to the mixed pixels challenge in digital imagery with emphasis on related technology flaws that exacerbate misclassification. The effects of heterogeneity in ground dataset and contribution to product accuracy are explicated. A case study of an unadulterated detailed AGB map output from multi-platform datasets is previewed to show real map aspect prior to generalization which is ordinarily subjective. Future opportunities are advanced for transferable metrics and models that incorporate a minimum data set of key covariates and fusion of multi-platform datasets.
