1The first all-season sample set for mapping global land cover with Landsat-8 data显示文摘We report the world's first all-season training and validation sample sets for global land cover classification with Landsat-8 data.Prior to this,such samples were only available at a single date primarily from the growing season.It is unknown how much limitation such a single-date sample has to mapping global land cover in other seasons of the year.To answer this question,we selected available Landsat-8 images from four seasons and collected training and validation samples from them.We compared the performances of training samples in different seasons using Random Forest algorithm.We found that the use of training samples from any individual season would result in the best overall classification accuracy when validated by samples in the same season.The global overall accuracy from combined best seasonal results was 67.2% when classifying the 11 Level-1 classes in the Finer Resolution Observation and Monitoring of Global Land Cover(FROM-GLC) classification system.The use of training samples from all seasons(named all-season training sample set hereafter) produced an overall accuracy of 67.0%.We also tested classification within 10° latitude 60° longitude zones using all-season training subsample within each zone and obtained an overall accuracy of 70.2%.This indicates that properly grouped subsamples in space can help improve classification accuracies.All the results in this study seem to suggest that it is possible to use an all-season training sample set to reach global optimality with universal applicability in classifying images acquired at any time of a year for global land cover mapping.Congcong Li Peng Gong Jie Wang Zhiliang Zhu Gregory S.

2The role of forensic anthropology in disaster victim identification(DVI):recent developments and future prospects显示文摘Forensic anthropological knowledge has been used in disaster victim identification(DVI)for over a century,but over the past decades,there have been a number of disaster events which have seen an increasing role for the forensic anthropologist.The experiences gained from some of the latest DVI operations have provided valuable lessons that have had an effect on the role and perceived value of the forensic anthropologist as part of the team managing the DVI process.This paper provides an overview of the ways in which forensic anthropologists may contribute to DVI with emphasis on how recent experiences and developments in forensic anthropology have augmented these contributions.Consequently,this paper reviews the value of forensic anthropological expertise at the disaster scene and in the mortuary,and discusses the way in which forensic anthropologists may use imaging in DVI efforts.Tissue-sampling strategies for DNA analysis,especially in the case of disasters with a large amount of fragmented remains,are also discussed.Additionally,consideration is given to the identification of survivors;the statistical basis of identification;the challenges related to some specific disaster scenarios;and education and training.Although forensic anthropologists can play a valuable role in different phases of a DVI operation,they never practice in isolation.The DVI process requires a multidisciplinary approach and,therefore,has a close collaboration with a range of forensic specialists.Hans H.de Boer Soren Blau Tania Delabarde Lucina Hackman 2019Forensic Sciences Research2019,4,4:3
