Estimation of above-ground biomass of a tropical forest in Northern Borneo using high-resolution satellite image
Estimating above-ground biomass is important in establishing an applicable methodology of Measurement, Reporting and Verification (MRV) System for Reducing Emissions from Deforestation and Forest Degradation-Plus (REDD+). We developed an estimation model of diameter at breast height (DBH) from IKO...

| Summary: | Estimating above-ground biomass is important in establishing an applicable methodology of Measurement, Reporting
and Verification (MRV) System for Reducing Emissions from Deforestation and Forest Degradation-Plus (REDD+). We
developed an estimation model of diameter at breast height (DBH) from IKONOS-2 image that led to above-ground
biomass estimation (AGB). The IKONOS image was preprocessed with dark object subtraction and topographic effect
correction prior to watershed segmentation for tree crown delineation. Compared to the field observation, the overall
segmentation accuracy was 64%. Crown detection percent had a strong negative correlation to tree density. In addition,
satellite-based crown area had the highest correlation with the field measured DBH. We then developed the DBH
allometric model that explained 74% of the data variance. In average, the estimated DBH was very similar to the
measured DBH as well as for AGB. Overall, this method can potentially be applied to estimate AGB over a relatively
large and remote tropical forest in Northern Borneo. |
