    Satellite data central to ocean monitoring

    Over 95% of Earth’s water is found in our oceans, and yet sadly, oceans are under stress from climate change and pollution. Monitoring our oceans is vital for Earth’s survival and satellites are the primary means of long-term and independent observation of our vast ocean bodies and their associated coastal zones.

    SkySat ESA archive

    The SkySat ESA archive collection consists of SkySat products requested by ESA supported projects over their areas of interest around the world and that ESA collected over the years. The dataset regularly grows as ESA collects new products. Two different product types are offered, Ground Sampling Distance at nadir up to 65 cm for panchromatic and up to 0.8m for multi-spectral. EO-SIP Product Type Product Description Content SSC_DEF_SC Basic and Ortho scene Level 1B 4-bands Analytic /DN Basic scene Level 1B 4-bands Panchromatic /DN Basic scene Level 1A 1-band Panchromatic DN Pre Sup resolution Basic scene Level 3B 3-bands Visual Ortho Scene Level 3B 4-bands Pansharpened Multispectral Ortho Scene Level 3B 4-bands Analytic/DN/SR Ortho Scene Level 3B 1-band Panchromatic /DN Ortho Scene SSC_DEF_CO Ortho Collect Visual 3-band Pansharpened Image Multispectral 4-band Pansharpened Image Multispectral 4-band Analytic/DN/SR Image (B, G, R, N) 1-band Panchromatic Image The Basic Scene product is uncalibrated, not radiometrically corrected for atmosphere or for any geometric distortions inherent in the imaging process: Analytic - unorthorectified, radiometrically corrected, multispectral BGRN Analytic DN - unorthorectified, multispectral BGRN Panchromatic - unorthorectified, radiometrically corrected, panchromatic (PAN) Panchromatic DN - unorthorectified, panchromatic (PAN) L1A Panchromatic DN - unorthorectified, pre-super resolution, panchromatic (PAN) The Ortho Scene product is sensor and geometrically corrected, and is projected to a cartographic map projection: Visual - orthorectified, pansharpened, and colour-corrected (using a colour curve) 3-band RGB Imagery Pansharpened Multispectral - orthorectified, pansharpened 4-band BGRN Imagery Analytic SR - orthorectified, multispectral BGRN. Atmospherically corrected Surface Reflectance product. Analytic - orthorectified, multispectral BGRN.

The product may contain artifacts resulting from the composing process, particular offsets in areas of stitched source scenes. Spatial coverage: Check the spatial coverage of the collection on a map available on the Third Party Missions Dissemination Service. As per ESA policy, very high-resolution imagery of conflict areas cannot be provided.

    SkySat Full Archive and New Tasking

    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. Basic Scene Product Components and Format Processing Levels Analytic (unorthorectified, radiometrically corrected, multispectral BGRN) Analytic DN (unorthorectified, multispectral BGRN) Panchromatic DN (unorthorectified, panchromatic) Product Components and Format Image File (GeoTIFF format) Metadata File (JSON format) Rational Polynomial Coefficients (Text File) UDM File (GeoTIFF format) Image Configuration 4-band Analytic DN Image (Blue, Green, Red, NIR) 1-band Panchromatic DN Image (Pan) Ground Sampling Distance 3.7 m at nadir (average at reference altitude 475 km) Ground Sampling Distance (nadir) Panchromatic 0.86m and Multispectral 1.0m for SkySat-1&2 Panchromatic 0.65m and Multispectral 0.8m for SkySat-3 to 13 (0.72 m and 1.0m for data acquired before 30/06/2020) 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.
