Frequently asked questions
Be aware that you will find pictures at a reduced spatial resolution compared to the original data, therefore, you can consider the possibility of purchasing the original data.
Q: Do I have to pay to obtain satellite data?
To access free data, read FAQ: How to get access to ESA Earth Observation data?
Q: How to get access to ESA Earth Observation data?
Data available under the simplified 'Registration' procedure is systematically generated and distributed online. See further details including the list of available products on the EOPI free dataset page.
See also the applicable prices for 'Third Party Mission' data.
As far as the ESA Earth Observation data coverage is concerned, you should make use of the EOLi-SA catalogue. The EOLI catalogue can be freely used for search and browsing. User ID and password for ordering are only provided upon approval of a project proposal/registration.
Extensive information on the various ESA Earth Observation Missions and Products is available on Earth Online.
Most of the Envisat and ERS data is available on the internet free of charge (Free Dataset) to anybody for science or operational use via registration at the dedicated ESA EOPI website (includes further details and the list of available products). The current Terms and Conditions for using those data do not allow reselling of the data.
Some data which is not yet available systematically on the internet (in particular SAR instrument tasking or some specific SAR data production) can still be obtained through two channels:
The Distributing Entities may authorise reselling and should be contacted directly for this purpose.
See also the ESA Data Policy.
Q: How to get ESA data acquired for the 'International Charter for Space and Major Disasters'?
The special planning performed by ESA for such events is reported on the ESA Earth Watching website.
Distribution of the relevant acquired satellite data is handled directly within the framework of the activated Charter, distributed commercially through the dedicated Distributing Entities (Category-2 priority) or to approved ESA project proposals upon ordering or access to online archives by registered users.
Q: How to get EO sample data and information on training?
See also the latest sample data , made freely available for specific events including: Bam Earthquake, Asia Earthquake & Tsunami and the Prestige oil spill over Galicia.
Extensive information on the ENVISAT Mission, products and applications is available on the ENVISAT web pages. See in particular the sections dedicated to 'Instruments' and 'Product Handbook' for the instrument of interest.
Should you be in need of other data covering a specific area and date range, please be advised that satellite data can be obtained from ESA free of charge via Registration (Free Dataset) or upon submission and approval of a project proposal (for Restrained Datasets/on demand planning and production) through the ESA Earth Observation Principal Investigator (EOPI) Portal depending on the products required. Further details are available from the EOPI restrained dataset page and 'How to Access' page.
For training and education, you can refer to the Library section on ESA Earth Online site. Many documents are available in full text and/or can be ordered directly online. See e.g. the CD-Rom 'ERS Spaceborne Radar Imagery' available in full text online.
We also draw your attention to the section dedicated to 'Education' on the ESA Portal. See e.g. the link to Eduspace were you will find information and case studies related to Remote Sensing presented in a user-friendly way.
