Project Proposal (Restrained): Access to this data collection is provided only after submitting and receiving approval for a project proposal. Access is limited to accepted projects that meet the conditions defined by ESA. 

Access Steps:

1. Create or log in to EO Sign In (users are recommended to register with an institutional email address)
2. Go to the ESA User Services Portal and submit the form with details of your proposed data use: 
   • Standard Pléiades provision.
   • OneAtlas Living Library subscription.
3. ESA will evaluate your proposal (normally within 9 weeks).
4. Go to the EO User Portal to check the status of your request
5. If approved, you will receive a confirmation email with the quota assigned and instructions on how to order the data. 

The collection is open for research and application development projects, exclusively for non-commercial and non-operational activities and for civil Earth observation research applications only. Access to the data requires submission of a Project Proposal, which is subject to evaluation and acceptance by ESA and the data owner.

ESA will support as many high-quality and innovative projects as possible within the quota limit available.

• Learn more about the quota limits and see a comparison across missions in our FAQ: How much data may I request in a Project Proposal?
• For guidance on preparing your proposal, see our How to access data requiring a project proposal guide
• Availability and restrictions to the use of the data are described in the Terms of Applicability document

The Pléiades twins (1A and 1B) deliver very high-resolution optical data (up to 0.5 m resolution Panchromatic and Colour and 2 m Multispectral) and offer a daily revisit capability to any point on the globe. The swath width is approximately 20 km (with a nadir footprint).

The ortho-products are automatically generated by the Pléiades ground segment, based on SRTM or Reference3D database. The projection available for Pléiades ortho-products is UTM, datum WGS84.

Spectral band combination options:

• Panchromatic: black and white image at 50 cm resolution
• Pansharpened: 3-bands or 4 bands colour image at 50 cm resolution
• Multispectral: 4 bands image at 2 m resolution 
• Bundle: 0.5 m panchromatic image + 2 m multispectral image, co-registered

There are two different geometric processing levels:

• Primary: The Primary product is the processing level closest to the natural image acquired by the sensor. This product restores perfect collection conditions: the sensor is placed in rectilinear geometry, and the image is clear of all radiometric distortion.
• Ortho: The Ortho product is a georeferenced image in Earth geometry, corrected from acquisition and terrain off-nadir effects. Available in Mono acquisition mode only. 

Acquisition modes:

• Mono
• Stereo
• Tristereo

To complement the traditional and fully customised ordering and download of selected SPOT, Pléiades or Pléiades Neo images in a variety of data formats, you can also subscribe to the OneAtlas Living Library package where the entire OneAtlas optical archive of ortho images is updated on a daily basis and made available for streaming or download.

The Living Library consists of

• less-than-18-months-old imagery
• a curation of SPOT images with no cloud cover and less than 30° incidence angle
• Pléiades images acquired worldwide with maximum 15% cloud cover and 30° Incidence Angle
• Pléiades Neo premium imagery selection with 2% cloud cover and 30° incidence angle

Each package provides access to both download and streaming options. Depending on their preferences and needs, users can choose streaming only, download only, or a combination of both. The amounts presented in the table reflect consumption based solely on one type—either streaming or download—from a single mission

All details about the data provision, data access conditions and quota assignment procedure are described in the Terms of Applicability available in the Resources section.

As per ESA policy, very high-resolution imagery of conflict areas cannot be provided.
