Your Gateway to Earth Observation

The eoPortal provides a trusted, accurate, and up to date gateway to knowledge and resources related to Earth Observation satellite missions.

Supporting the Mission of the European Space Agency


The eoPortal is motivated by a set of broader goals centred around explaining, demonstrating, and promoting the capabilities of space systems to bring benefits to citizens around the world. The work of the eoPortal is supported by the European Space Agency (ESA) and in line with its mission:

The European Space Agency is Europe’s gateway to space. Its mission is to shape the development of Europe’s space capability and ensure that investment in space continues to deliver benefits to the citizens of Europe and the world.

Observation of the Earth and its Environment


The eoPortal is based on the foundational work of Dr. Herbert Kramer whose years of publication of contents on the Portal have made it the valued resource it is today.


Today the eoPortal remains focused on satellite missions providing observations of the Earth and its Environment, and its content is curated by a dynamic team of contributors who can be contacted at The eoPortal is indexed using information from ‘The Earth Observation Handbook’ and associated CEOS Database, assembled and maintained by the Committee on Earth Observing Satellites.

Realising Our Objectives


The eoPortal pursues its objectives by:


  • Growing awareness of space systems, Earth observation satellites and their applications
  • Supporting current and future users of services provided from space, focused on Earth observation, by providing valuable, usable reference information
  • Increasing understanding of the purpose and roles of space systems and Earth observation satellites
  • Engaging the broader technology sector in the importance and capabilities of space systems and Earth observation satellites
  • Providing pathways for users to progress from knowledge about space systems and Earth observation satellites to adoption of these technologies, and incorporation into their work and activities
  • Nurturing and engaging the community of EO Portal users to bring about advocacy for Earth observation and space systems more broadly
  • Participating in, and shaping the dialogue around Earth observation and space communities about important societal and commercial services from space

Serving Community


The content of the eoPortal is developed for:


  • Space community - those involved in space systems whose mission is not primarily Earth observation. This may include government space agencies or other government departments who are heavily involved in space activities, as well as the space industry.
  • Technology community - including those involved in the application of various, often integrated, technology solutions for research and development, product or application development, and generally the development of non-space technologies.
  • Research community focused on basic research topics which may be directly or indirectly related to the development of Earth observation systems, and may or may not be technically oriented.
  • Policy and decision makers - looking at the drivers for the development of space and broader technology policy, including decisions around which space systems to build, design, fund, or invest in.
  • Educational community - across all educational levels and sectors who teach, learn, or are interested in learning more about Earth observation technologies.
  • Enthusiasts and the general public - who are curious about the capabilities of space systems, Earth observation, and how they work.
  • Anyone interested in exploring!
