TY - JOUR AU1 - Ogunjemiyo, Segun AU2 - Roberts, Dar AU3 - Ustin, Susan AU4 - Parker, Geoffrey AB - Data from small and large footprint lidar systems were used to derive basic forest attributes from old-growth Douglas fir/western hemlock dominated stands at the Gifford Pinchot National Forest in the Pacific Northwest of United Sates. The derived forest attributes include canopy height and canopy closure. The crown depth estimates were made from the large footprint dataset. The study provides the unique opportunity to compare basic forest attributes derived from small and large footprint lidar systems, and also demonstrates the significance of complimentary analysis of data from different lidar systems in providing expanded information on forest structure. Results of the analysis showed a high degree of agreement between the canopy height estimates from both lidar systems TI - Comparison of small and large footprint lidar systems in predicting forest structural characteristics JF - Proceedings of SPIE DO - 10.1117/12.681034 DA - 2006-08-31 UR - https://www.deepdyve.com/lp/spie/comparison-of-small-and-large-footprint-lidar-systems-in-predicting-aWUA0W8I4x SP - 629803 EP - 629803-9 VL - 6298 IS - 1 DP - DeepDyve ER -
