SkySat Archive
The rich archive is perfect for monitoring historical change and assessing trends with the most recent before and after images available, and for use to train machine learning and computer vision algorithms.
Two SkySat products are available:
- SkySat Basic Scene Product (L1), that includes Analytic, Analytic DN, L1A Panchromatic DN, and Panchromatic imagery that is uncalibrated and in a raw digital number format. The Basic Scene Product is not corrected for any geometric distortions inherent in the imaging process, and is not mapped to a cartographic projection.
- SkySat Ortho Scene Product (L3), that includes Visual, Analytic DN, Analytic, Panchromatic, and Pansharpened Multispectral imagery. The Ortho Scene product is sensor- and geometrically-corrected, and is projected to a cartographic map projection. The geometric correction uses fine Digital Elevation Models (DEMs) with a post spacing of between 30 and 90 meters.
Please see the table below for more details about each level. There is no minimum AOI for SkySat archive data. Please note the minimum purchase price for archive data is €4,500.00.

FAQs
The SkySat L1 Basic Scene product is a Scaled Top of Atmosphere Radiance (at sensor) and sensor corrected product, without correction for any geometric distortions inherent in the imaging processes and is not mapped to a cartographic projection. The imagery data is accompanied by Rational Polynomial Coefficients (RPCs) to enable orthorectification by the user. This kind of product is designed for users with advanced image processing and geometric correction capabilities.
The SkySat L3 Ortho Scene product is radiometrically-, sensor- and geometrically- corrected and is projected to a cartographic map projection. The geometric correction uses fine Digital Elevation Models (DEMs) with a post spacing of between 30 and 90 meters.
