Cookie Notice for Earth Online

Earth Online presents news and information on European Space Agency (ESA) activities in the field of Earth observation. The website enables visitors to learn all about ESA’s Earth Observation data, and the satellite missions and instruments that acquire this data.

The use of cookies by ESA

ESA uses cookies generated by an open source web analytics platform called Matomo to measure the effectiveness and efficiency of Earth Online. The cookies help ESA to know which pages are visited most often and to ensure that the Earth Online website responds effectively to users' needs.

If you do not wish to receive a cookie, or if you wish your browser to notify you when you receive a cookie, you may use the option on your web browser to disable cookies or you can opt out using the 'Opt-out' option below. However, please note that if you disable all cookies you may not be able to take advantage of all the features available on this website.

Anonymised information generated by these cookies will be collected and processed on behalf of ESA by Airbus Defence and Space Limited (Airbus UK) and Eversis Sp. Z.o. o. (Eversis), and subsequently transmitted to ESA in the form of statistics reports.

ESA, Airbus UK and Eversis do not use information generated by these cookies either for promotion or marketing purposes, and they will not share the information with any third party.

About the analytics tool used by ESA

Matomo is an open source web analytics platform which complies with the EU’s General Data Protection Regulation (GDPR) of 27 April 2016. This means that Matomo ensures end-user data protection, thanks to features such as source data anonymisation and opt-out mechanisms for users.

Cookies generated by Matomo enable ESA to track information about visitors in an anonymised form. Examples of such information are:

  • the user’s anonymised internet protocol (IP) address. Matomo uses an IP anonymisation mechanism which automatically masks a portion of each user's IP, effectively making it impossible to identify a particular visitor from the remaining information.
  • location: country, region (geolocation)
  • date and time of the visit to the site
  • title of the page being viewed

The cookies are first party persistent cookies which also enable ESA to monitor repeat visits. Using a random unique visitor ID, the software is able to distinguish between the first visit and subsequent visits made by the user, to improve the accuracy of the reports.

Opt-out features

By default, website visitors are tracked using the first-party persistent cookies from Earth Online. You may choose not to be tracked by Matomo (opt-out). If you change your mind, you can choose to be tracked again by Matomo (opt-in). Please note that if you opt out, it will not be possible to take your use of the website into account when ESA improves the user experience of the Earth Online website.


Restricted access to information

All analytics data communication is encrypted via SSL protocol. Matomo generates analytical reports on the basis of the anonymised data, and these reports are distributed to ESA, Airbus UK and Eversis, which may be required to analyse, develop and/or maintain the Earth Online website.

Deleting old visitors logs

Matomo automatically deletes visitors' logs after 12 months. The aggregated data reports are stored for an indefinite period by ESA for analysis purposes.

Social Media Sharing

Users logged in to Facebook/Twitter may experience some additional tracking when interacting with the social sharing buttons on our pages as clarified within the Terms and Conditions of their agreement with Facebook/Twitter, though no such information is collected/relayed/made available to ESA at any point.
