Abstract
 Analysis of Forest Structure Using LiDAR in South Korea Track: Forestry, Wildlife, and Fisheries Management Author(s): Doo-Ahn Kwak, Woo-Kyun Lee, Min-Ho Son LiDAR (Light Detection And Ranging) makes it possible to detect and measure individual trees. In this study, a method that estimated position, height, diameter at breast height of individual trees, stand volume and accuracy of digital elevation model derived from of LiDAR data was validated with field data. Tree species used for accuracy measurement were Pinus Koraiensis, Larix Leptolepis and Quercus spp. Because all the tree in this study were measured with high accuracy, their positions could be matched with laser point LIDAR data, making validation on an individual tree basis possible. DBH estimated with LiDAR data has highly accurate and stand volume estimated with end-area equation was validated. DEM from LiDAR data had 0.3m spatial resolution and was moe accurate than 1:5,000 and 1:2,5000 Digital Maps.
