How To Access Data

Project Proposal (Restrained)

  1. Go to the ESA User Services Portal
  2. Register or log in to EO Sign In
  3. After logging in, complete and submit the form with your proposed use of the data
  4. The proposal will be evaluated by ESA, which normally takes between 4 and 6 weeks
  5. Upon successful evaluation, you will receive a confirmation email, which describes the amount of data to be provided, and details of how to order the data.

The collection is open for research and application development projects only to users located in the territory of ESA Member States (including Canada), in the European Commission Member States.

Data are available to order on demand upon submission of a Project Proposal 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, therefore only a limited amount of products can be allowed to each project.

The products are available as part of the Planet provision from the RapidEye, SkySat and PlanetScope constellations. The SkySat collection has worldwide coverage: The Planet Explorer Catalogue can be accessed (Planet registration requested) to discover and check the data readiness.

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

If you need help with the proposal form, consult this guide on how to access data requiring a project proposal.

Should you need support to prepare your proposal or access the data, please contact EOHelp.

Description

The SkySat Level 2B Basic Scene, Level 3B Ortho Scene and Level 3B Consolidated full archive and new tasking products are available as part of Planet imagery offer.

The SkySat Basic Scene product is uncalibrated and in a raw digital number format, not corrected for any geometric distortions inherent in the imaging process. Rational Polynomial Coefficients (RPCs) is provided to enable orthorectification by the user.

  • Analytic DN (unorthorectified, multispectral BGRN)
  • Panchromatic DN (unorthorectified, panchromatic)

  • Panchromatic 0.86m and Multispectral 1.0m for SkySat-1&2
  • Panchromatic 0.65m and Multispectral 0.8m for SkySat-3 to

Accuracy<50 m RMSE

 

The SkySat Ortho Scene is sensor- and geometrically-corrected (by using DEMs with a post spacing of between 30 and 90 meters) and is projected to a cartographic map projection; the accuracy of the product will vary from region to region based on available GCPs. Different products are available:

  • The SkySat Visual Ortho Scene product is orthorectified, pansharpened, and color-corrected (using a color curve) 3-band RGB Imagery
  • The SkySat Pansharpened Multispectral Scene product is orthorectified, pansharpened 4-band BGRN Imagery
  • The SkySat Analytic DN Ortho Scene product is orthorectified, multispectral BGRN, uncalibrated, digital number imagery product. The product has been processed to remove distortions caused by terrain; It eliminates the perspective effect on the ground (not on buildings), restoring the geometry of a vertical shot. Transformation to at-sensor radiance is not included
  • The SkySat Panchromatic DN Ortho Scene product is orthorectified, panchromatic, uncalibrated, digital number imagery product. It has a finer GSD than the Analytic Product. Transformation to at-sensor radiance is not included.
  • The SkySat Analytic Ortho Scene are calibrated multispectral imagery products with radiometric corrections applied to correct for any sensor artifacts and transformation to top-of-atmosphere radiance.
  • The SkySat Consolidated Product are Ortho Collect product created by composing ~60 SkySat Ortho Scenes (Visual, Pansharpened Multispectral, Analytic DN, Panchromatic DN) along an imaging strip into segments
