The study was conducted to verify application developed an Automatic Forest Resource Investigation Program (AFRIP) of the Terrestrial Laser Scanning (TLS) for accuracy, speed and effectiveness of forest resource investigation. We set up study plot(plot size 30m × 30m) and investigated sample plot survey. Simultaneously, compared and analyzed to expert survey and terrestrial laser scanner Study site located Daegwallyeong, Gangneung city, Gwangwondo with Pinus densifora stand, 10 class of Age, 51.8cm of DBH and 22.6m of tree height. The results of analysis are 51.8cm of average DBH and 22.6m of tree height in expert survey, 50.9cm and 23.0m in Terrestrial Laser Scanning(TLS) and 51.6cm and 23.1m in developed automatic analyzing program of TLS. The deviation of measurement were 0.9cm and 0.2cm in DBH and –0.4cm and –0.5cm among expert survey, Terrestrial Laser Scanning(TLS) and automatic 3D analyzing program in measurement of DBH and tree height, there were no significant difference among three measurements. And it taken measuring data accurately and rapidly in forest survey by TLS in results of this study. Especially the applied automatic program in this study, the TLS showed precise measurements of measured DBH and height to the extent to which little difference was found between the outcomes by expert. Hence, it is expected to be applied with efficiency on the forest inventory spot.
