Hazards Data Distribution System

The Hazards Data Distribution System (HDDS) Explorer is a unique collection of imagery and documents designed to assist in the response to natural and man-made disasters. Like a traditional web-based interface to an imagery archive (such as EarthExplorer), HDDS provides geographic search capabilities based on latitude and longitude boundaries and other criteria. HDDS contains imagery acquired in the aftermath of a disaster as well as imagery of the same region before the event.

灾害数据分发系统（Hazards Data Distribution System，HDDS）探索器是一套独特的影像与文档集合，旨在为自然灾害与人为灾害的应急响应提供支持。与传统的影像存档网络界面（如EarthExplorer）类似，HDDS支持基于经纬度范围及其他筛选条件的地理检索功能。该系统既收录了灾害发生后获取的影像资料，也包含对应区域灾前的影像数据。
