ESA Earth Online

The name Earth Online derives from ESA's Earthnet programme. Earthnet prepares and attracts new ESA Earth Observation missions by setting the international cooperation scheme, preparing the basic infrastructure, building the scientific and application Community and competency in Europe to define and set-up own European Programmes in consultation with member states. Earth Online is the entry point for scientific-technical information on Earth Observation activities by the European Space Agency (ESA). The web portal provides a vast amount of content, grown and collected over more than a decade: Detailed technical information on Earth Observation (EO) missions; Satellites and sensors; EO data products & services; Online resources such as catalogues and library; Applications of satellite data; Access to promotional satellite imagery. After 10 years of operations on distinct sites, the two principal portals of ESA Earth Observation - Earth Online (earth.esa.int) and the Principal Investigator's Portal (eopi.esa.int) have moved to a new platform. ESA's technical and scientific earth observation user communities will from now on be served from a single portal, providing a modern and easy-to-use interface to our services and data.

地球在线（Earth Online）之名源于欧洲航天局（ESA）的地球网计划。地球网计划通过设定国际合作方案、构建基础架构、培育科学与应用社群以及提升欧洲在定义和设立自主欧洲项目方面的能力，为ESA的新地球观测任务做准备并吸引其加入。地球在线是欧洲航天局（ESA）地球观测活动的科学-技术信息的入口点。该网络门户汇集了超过十年的丰富内容：包括地球观测（EO）任务的详细技术信息、卫星与传感器、地球观测数据产品与服务、在线资源如目录与图书馆；卫星数据的应用以及促销卫星图像的访问。在独立运营了十年之后，ESA地球观测的两个主要门户——地球在线（earth.esa.int）和主要研究员门户（eopi.esa.int）——现已迁移至新平台。自此，ESA的技术与科学地球观测用户社群将由单一门户提供服务，该门户提供了一个现代化且易于使用的界面，以供我们服务与数据的访问。
