Visibility analysis of oceanic blue space using digital elevation models
Yi Qiang,Suwan Shen,Qi Chen +2 more
TL;DR: In this article, the authors applied an innovative sampling strategy which generalizes blue space as a lattice of points and calculate visibility of all the points within a continuous area, compared to traditional viewpoint-based visibility analyses, this approach can assess blue space visibility over a large area at a fine spatial resolution.
Journal ArticleDOI
Improvement of the Edge-based Morphological (EM) method for lidar data filtering
TL;DR: This study introduces a new method to identify buildings so that the total number of parameters to be tuned is reduced from 7 to 2 and it was found that the average filtering error slightly decreased compared to the original algorithm when tested with the benchmark dataset provided by the ISPRS Commission III/WG3.
Journal ArticleDOI
Hyperspectral Estimation of Canopy Leaf Biomass Phenotype per Ground Area Using a Continuous Wavelet Analysis in Wheat.
Xia Yao,Haiyang Si,Tao Cheng,Min Jia,Qi Chen,Yongchao Tian,Yan Zhu,Weixing Cao,Chaoyan Chen,Jiayu Cai,Rongrong Gao +10 more
TL;DR: The potential of precision phenotyping to assess the dynamic genetics of complex traits, especially those not amenable to traditional phenotypesing are highlighted.
Journal ArticleDOI
Local validation of global biomass maps
TL;DR: validation entailed assessing the accuracy of map-based estimates of mean biomass per unit area for a sub-global, approximate 7600-km2 validation site in Minnesota, United States of America (USA).
Journal ArticleDOI
Individual and Interactive Influences of Anthropogenic and Ecological Factors on Forest PM2.5 Concentrations at an Urban Scale
Guoliang Yun,Shudi Zuo,Shaoqing Dai,Xiaodong Song,Chengdong Xu,Yilan Liao,Peiqiang Zhao,Weiyin Chang,Qi Chen,Yaying Li,Jianfeng Tang,Wang Man,Yin Ren +12 more
TL;DR: It is suggested that in order to reveal the direct and indirect effects of human activities and multiple factors on PM2.5 concentrations in urban forests, quantification of fusion satellite data and spatial statistical methods should be conducted in urban areas.
