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.
The ESA Earth Observation Users' Single Sign On will manage a unique user name and password for many activities. Before registering to individual services you have to register in the single sign on. If you have already registered in the single sign on (and weren't already logged in somewhere) then don't register again, just click “I'm already registered” and enter your user name/password.
