Abstract

Study on estimating carbon storage biomass of Dipterocarpus alatus Roxb. ex G.Don using unmanned aircraft Vehicle (UAV) 1,450 trees in KhonKaen University area. The study found that there is a positive relationship between height and circumference trees, and a coefficient of decision (R2 = 0.78). An equation for predicting the circumference (cm) = 7.854*height(m) - 8.587. The results of aerial photograph processing showed 3 layers Orthophoto, Digital Elevation Model (DEM) and Digital Terrain Model (DTM) at resolutions of 2.42, 4.81 and 4.81 cm respectively. Interpret 906 tree-shaped canopy and analyze the height trees to predict the circumference of trees. The study was found that the Dipterocarpus alatus Roxb. ex G.Don in KhonKaen University area had the biomass equal to 820.32 tons and the carbon storage by 385.55 tons in the biomass.
