Skysat Imagery Product SpecificationCOLLECTION TYPESSTANDARD IMAGEFigure 1: A single “site,” or a standard SkySatimage deliverable. Image width varies withsatellite and collection angle; 6.6 kmrepresents the minimum width.VIDEOFull motion videos are collected between 30 and 120 seconds by a single camera from any of the active SkySats.Videos are collected using only the Panchromatic half of the camera, hence all videos are PAN only.Videos are packaged and delivered with a video mpeg-4 file, plus all image frames with accompanying videometadata and a frame index file (reference Product Types below).

Skysat Imagery Product SpecificationPRODUCT TYPESSCENESBasicThe SkySat Basic Scene product includes Analytic, Analytic DN, and Panchromatic imagery that is uncalibratedand in a raw digital number format. The Basic Scene Product is not corrected for any geometric distortionsinherent in the imaging process.Imagery data is accompanied by Rational Polynomial Coefficients (RPCs) to enable orthorectification by theuser. This product is designed for users with advanced image processing capabilities and a desire togeometrically correct the product themselves.The SkySat Basic Scene Product has a sensor-based framing, and is not mapped to a cartographic projection.

Skysat Imagery Product SpecificationOrthoThe SkySat Ortho Scene product includes Visual, Analytic DN, Analytic, Panchromatic, and PansharpenedMultispectral imagery. The Ortho Scene product is sensor- and geometrically-corrected, and is projected to acartographic map projection. The geometric correction uses fine Digital Elevation Models (DEMs) with a postspacing of between 30 and 90 meters.Ground Control Points (GCPs) are used in the creation of every image and the accuracy of the product will varyfrom region to region based on available GCPs.
