Forest Emission Factor Database
Forest biomass can be estimated from field measurement, remote sensing, and GIS-based approach; whereas the field measurement is considered to be more accurate. This field measurement involves selection of sample trees, measurement of predictors (diameter at breast height, height, wood density, crown length etc.) and output variable (biomass from destructive of semi-destructive methods). Finally, allometric models are developed from the field inventory data of these predictors and output variables. In other way, volume allometric models can also be used to estimate the tree biomass by converting the estimated volume into biomass using the wood density value of the respective species. This modules provide databases for allometric equations, wood density, raw data and tree species list.
