Analysis-Ready PlanetScope
About Analysis-Ready PlanetScope
This product includes derived imagery from PlanetScope sensors.
Analysis-Ready PlanetScope combines data from the three available PlanetScope sensors (Dove Classic, Dove-R, and SuperDove) while enhancing temporal and spatial consistency with trusted, third-party data sources (Landsat, Sentinel-2, MODIS, VIIRS). This is accomplished with a proprietary algorithm that creates pre-processed, harmonized, and spatially consistent near-daily stacks of images that enable time-series analysis and machine learning applications. It delivers four surface reflectance bands: blue, green, red, and near-infrared.
The earliest Analysis-Ready PlanetScope imagery is available on January 01, 2017. The product is produced on demand when a subscription is initiated.
Product Overview
Planet offers Analysis-Ready PlanetScope (ARPS) imagery as a 3 m orthorectified (corrected for terrain distortions) surface reflectance product (ARP-SR). The data is stored in 16-bit integer format (with a multiplication factor of 10,000) as cloud-optimized geotiffs compressed using LZW compression. During processing and harmonization, 4-band PS TOA Reflectance (PS-TOAR) (converted from the radiances) are transformed into surface reflectances, ensuring radiometric consistency with FORCE-processed Sentinel-2 and Landsat. As a result, the spectral bands and spectral response functions of ARPS data will be equivalent to the blue (B2), green (B3), red (B4), and narrow NIR (B8a) bands of Sentinel-2 (ESA 2024). The surface reflectance data represent Normalized BRDF Adjusted Reflectances (NBAR) as the Landsat 8/9 and Sentinel-2 data used for cross-calibration have been normalized to the nadir view. Enhanced geometric performance includes temporal positional accuracy of <4m RMSE PCTL90.
The surface reflectance product is accompanied by a Quality Assurance product (ARP-QA) in GeoTIFF format. The QA product is a 2-layer thematic raster using the same spatial grid as the corresponding Analysis-Ready PlanetScope spectral data. Layer 1, Cloud and shadow mask, contains information denoting usable data using seven classifications that allow users to remove pixels that are not useful after they download the image. Layer 2, Pixel provenance has integers that can be mapped to PlanetScope scene IDs using the information in the QA raster's metadata header.
Analysis-Ready PlanetScope products are projected in the UTM zone intersected by their extent using the WGS-84 horizontal datum.
