Accurately quantifying the above-ground carbon stock of tropical rainforest trees is the core component of "Reduction of Emissions from Deforestation and Forest Degradation-plus" (REDD+) projects and is important for evaluating the effects of anth...

REMOTE SENSING OF ENVIRONMENT 173 304-313 2016年2月 [査読有り]
Human activities in tropical forests, such as logging or shifting cultivation, largely affect forest biodiversity. These disturbances often create small patches of successional vegetation and heterogeneous spatial patterns. Airborne LiDAR can dete...
Inter-annual canopy growth is one of the key indicators for assessing forest conditions, but the measurements require laborious field surveys. Up-to-date LiDAR remote sensing provides sufficient three-dimensional morphological information of the g...

We estimated inter-annual growth of broad-leaved trees planted in the urban park, by using multi-temporal airborne LiDAR datasets acquired in 2004, 2008, and 2010. The annual changes in the LiDAR-estimated growth of average canopy heights were sig...
