The complete PlanetScope constellation of approximately 430+ active satellites is able to image nearly the entire land surface of Earth every day (equating to a daily collection capacity of 350 million km²/day). The constellation is constantly "on" and does not require ordering or acquisition planning.

Science

PlanetScope satellite imagery is captured as a continuous strip of single frame images known as "scenes".

Scenes are derived from multiple generations of PlanetScope satellites.

Older-generation of PlanetScope satellites acquired a single RGB (red, green, blue) frame or a split-frame with a RGB half and a NIR (near-infrared) half, depending on the capability of the satellite.

The new generation of PlanetScope satellites (PS2.SD referred to as Dove-R and PSB.SD referred to as SuperDove) acquire images with a multistripe frame with bands divided between RGBNIR (Dove-R) or RGBNIR, red edge, green I, yellow and coastal blue (SuperDove). SuperDove satellites were launched in early 2020 and started producing imagery in mid-March 2020. PSB.SD PlanetScope satellites reached near daily cadence in August 2021. Starting on 29 April 2022 all new PlanetScope images have 8-bands and are from SuperDoves. The 8-Band PlanetScope images can be obtained using all Planet Platforms, Integrations and API. The item-type is PSScene.

Planet offers three product lines for PlanetScope imagery: a Basic Scene product, an Ortho Scene product, and an Ortho Tile product.

The Basic Scene product is a scaled Top of Atmosphere Radiance (at sensor) and sensor-corrected product. The Basic Scene product is designed for users with advanced image processing and geometric correction capabilities. The product is not orthorectified or corrected for terrain distortions.

Ortho Scenes represent the single-frame image captures as acquired by a PlanetScope satellite with additional post processing applied. The Ortho Scene products are available in Surface Reflectance and Analytic Radiance (Top of Atmosphere corrected) in 4- and 8-bands, as well as the 3-band visual product.

Ortho Tiles are multiple orthorectified scenes in a single strip that have been merged and then divided according to a defined grid.

Planet provides a “harmonization” tool in all Planet platforms to perform a rigorous approximate transform of the Surface Reflectance measurements of the Dove-C (PS2) instrument PlanetScope satellites to the Surface Reflectance equivalents from Dove-R and SuperDove instrument PlanetScope satellites. This is done by using Sentinel-2 as target sensor. Read technical details of normalizing data in Scene Level Normalization and Harmonization of Planet Dove Imagery. The harmonization process only applies to bands with a PS2 equivalent - specifically Blue, Green, Red, and Near-infrared - and only for Surface Reflectance values.
