Diseases/Epidemics Data Pathfinder (DE-Pathfinder)

The Diseases/Epidemics Data Pathfinder (DE-Pathfinder) is one of several Data Pathfinders NASA designed to help guide users through the process of selecting and using application-specific datasets from NASA’s Earth science data collections. It is the result of collaboration with other federal entities and international space organizations to provide information to help understand how environmental changes can lead to disease emergence, transmission, and outbreaks. Remote sensing data are used to map, monitor, and predict areas or regions at risk for disease outbreaks. Satellite imagery, coupled with ground-based data, aids in understanding many natural phenomena and human behaviors. The data products, which are openly available, have been used to understand disease outbreaks such as malaria, Rift Valley fever, and COVID-19, and how changes in human behavior are having impacts on the environment. The World Health Organization notes that disease outbreaks are often associated with environmental conditions. Changes in water and air quality, temperature, and precipitation for example, can affect disease transmission.

疾病/流行病数据探路者（Diseases/Epidemics Data Pathfinder，DE-Pathfinder）是美国国家航空航天局（National Aeronautics and Space Administration，NASA）推出的多款数据探路者项目之一，旨在引导用户顺利完成从NASA地球科学数据馆藏中筛选并使用特定应用场景数据集的流程。本项目由NASA联合其他联邦机构及国际航天组织合作打造，旨在提供相关信息，助力学界理解环境变化如何引发疾病的出现、传播与暴发。遥感数据可用于绘制、监测并预判疾病暴发风险区域。卫星影像结合地面观测数据，可为解析诸多自然现象与人类行为模式提供支撑。该类数据产品均面向公众开放获取，已被广泛用于研究疟疾、裂谷热、新型冠状病毒肺炎（COVID-19）等疾病的暴发情况，以及人类行为变化对环境造成的影响。世界卫生组织（World Health Organization，WHO）指出，疾病暴发往往与环境条件紧密关联。例如，水质、空气质量、气温及降水量的变化，均可能对疾病传播产生影响。
