Description
Planet's SkySat satellite constellation provides high-resolution Earth observation imagery. The dataset includes a full archive and new tasking products, offering uncalibrated Basic Scenes and geometrically-corrected Ortho Scenes in panchromatic and 4-band multispectral (Blue, Green, Red, NIR) configurations. Products are available via the NASA Earthdata platform as part of the Planet imagery offer.
Use Cases
Land cover classification based on 4-band multispectral (BGR-NIR) imagery.
High-resolution feature detection and mapping based on panchromatic imagery with sub-meter ground sampling distance.
Change detection and time-series analysis based on the full archive and new tasking capability.
Orthorectification and geometric correction workflows based on provided Rational Polynomial Coefficients (RPCs).
Pansharpening and visual analysis based on the Ortho Pansharpened and Ortho Visual Scene products.
Strengths
Offers very high spatial resolution, with ground sampling distances ranging from 0.57 m to 0.86 m for panchromatic and 0.75 m to 1.0 m for multispectral bands.
Provides multiple processing levels (Basic and Ortho) and product types (panchromatic, multispectral, pansharpened) to suit different user needs.
Includes Rational Polynomial Coefficients (RPCs) for user-led orthorectification of Basic Scene products.
Specifies a geolocation accuracy of less than 50 meters RMSE.
Limitations
Description metadata is limited; actual data quality, file formats, and size require manual inspection after download.
Row count and temporal coverage are unknown, which may limit suitability assessment for time-series projects.
The accuracy of Ortho Scene products varies regionally based on available ground control points.
