China Health and Nutrition Survey (CHNS)
China Health and Nutrition Survey(CHNS)是一项由美国北卡罗来纳大学人口中心与中国疾病预防控制中心营养与健康所合作开展的长期开放性队列研究项目,旨在评估国家和地方政府的健康、营养与家庭计划政策对人群健康和营养状况的影响,以及社会经济转型对居民健康行为和健康结果的作用。该调查覆盖中国15个省份和直辖市的约7200户家庭、超过30000名个体,采用多阶段随机抽样方法,收集了家庭、个体以及社区层面的详细数据,包括饮食、健康、经济和社会因素等信息。自2011年起,CHNS不断扩展,新增多个城市和省份,并持续完善纵向数据链接,为研究中国社会经济变化与健康营养的动态关系提供了重要的数据支持。

Population and Housing Census of 2007 - Ethiopia
Geographic coverage --------------------------- National coverage Analysis unit --------------------------- Household Person Housing unit Universe --------------------------- The census has counted people on dejure and defacto basis. The dejure population comprises all the persons who belong to a given area at a given time by virtue of usual residence, while under defacto approach people were counted as the residents of the place where they found. In the census, a person is said to be a usual resident of a household (and hence an area) if he/she has been residing in the household continuously for at least six months before the census day or intends to reside in the household for six months or longer. Thus, visitors are not included with the usual (dejure) population. Homeless persons were enumerated in the place where they spent the night on the enumeration day. The 2007 census counted foreign nationals who were residing in the city administration. On the other hand all Ethiopians living abroad were not counted. Kind of data --------------------------- Census/enumeration data [cen] Mode of data collection --------------------------- Face-to-face [f2f] Research instrument --------------------------- Two type sof questionnaires were used to collect census data: i) Short questionnaire ii) Long questionnaire Unlike the previous censuses, the contents of the short and long questionnaires were similar both for the urban and rural areas as well as for the entire city. But the short and the long questionnaires differ by the number of variables they contained. That is, the short questionnaire was used to collect basic data on population characteristics, such as population size, sex, age, language, ethnic group, religion, orphanhood and disability. Whereas the long questionnaire includes information on marital status, education, economic activity, migration, fertility, mortality, as well as housing stocks and conditions in addition to those questions contained in a short questionnaire.

SeaDronesSee
SeaDronesSee是由德国图宾根大学认知系统组创建的大型视觉对象检测和跟踪基准,专注于海洋环境中的人类检测。该数据集包含超过54,000帧,总计400,000个实例,从不同高度和视角(5至260米,0至90度)捕获,并提供详细的元信息。数据集的创建旨在填补陆基视觉系统与海基系统之间的差距,特别适用于无人机辅助的海上搜救任务。SeaDronesSee通过提供精确的元数据,如高度、视角和速度,支持多模态系统的开发,以提高检测的准确性和速度。此外,数据集还包括多光谱图像,利用非可见光谱(如近红外和红边光谱)来增强人类检测能力。
