PlanetScope 3-band multispectral basic and orthorectified scenes. This data set includes imagery from PlanetScope-0 and PlanetScope-1 sensors as well as full-frame and split-frame PlanetScope-2 sensors. Newer PSScene3Band items have a corresponding PSScene4Band item.
Products Overview
The visual and analytic products are in GeoTIFF format and the basic scene products are available as either NITF or GeoTIFFs. The GeoTIFFs are resampled at 3 meters and projected in the UTM projection using the WGS84 datum. An alpha mask is provided as a binary color channel, and can be used to remove or hide low quality pixels near the periphery of a given scene. This mask compensates for effects due to vignetting, low SNR, or hot or cold pixels.
PlanetScope satellites collect imagery as a series of overlapping framed scenes, and are not organized to any particular grid system. The Ortho Scene products enable users to create seamless imagery by stitching together PlanetScope Ortho Scenes of their choice and clipping it to a tiling grid structure as required.
The PlanetScope Ortho Scene product is orthorectified and is designed for applications that require imagery with an accurate geolocation and cartographic projection. It has been processed to remove distortions caused by terrain and can be used for cartographic purposes. The Ortho Scenes are delivered as visual (RGB) and analytic products. Ortho Scenes are radiometrically, sensor, and geometrically corrected products that are projected to a cartographic map projection. The geometric correction uses fine Digital Elevation Models (DEMs) with a post spacing 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 vary from region to region based on available GCPs.

Item Properties
Property Name | Description | Type |
---|---|---|
_permissions | Assets available for the item which the authenticated user has permission to download. | array |
geometry | Geographic boundary of the item's footprint, formatted as a GeoJSON polygon. | json |
id | Globally unique item identifier. | string |
acquired | Timestamp that the item was captured. | datetime |
anomalous_pixels | Percentage of pixels that may have errors. Represented spatially in the UDM. | double |
cloud_cover | Average percentage of cloud coverage. | double |
columns | Number of columns in the image. | integer |
epsg_code | Ortho tile grid cell that the item is located in (not used if Scene). | integer |
ground_control | Positional accuracy of the item. If the item has uncertain positional accuracy, this value will be false. | boolean |
gsd | Ground sample distance - the distance between pixel centers as measured on the ground in meters. | double |
instrument | Name of the satellite instrument used to collect the image. | string |
item_type | Name of the item type. | string |
origin_x | ULX coordinate of the extent of the data. The coordinate references the top left corner of the top left pixel. | double |
origin_y | ULY coordinate of the extent of the data. The coordinate references the top left corner of the top left pixel. | double |
pixel_resolution | Pixel resolution of the imagery in meters. | double |
provider | Name of the item provider (e.g. "planetscope", "rapideye"). | string |
published | Timestamp that the item was published to the Planet API. | datetime |
publishing_stage | Stage of publishing for an item. Urectifiable or open water PSScene3Band items (<5%) will start and remain in "preview" stage. Most items (>95% ) will be first published in "standard" stage and graduate to a "finalized" stage. | string |
quality_category | Planet image quality metric: "standard" or "test". To qualify for "standard" image quality an image must meet a variety of quality standards, for example: PAN motion blur less than 1.15 pixels, compression bits per pixel less than 3. If the image does not meet these criteria it is considered "test" quality. | string |
rows | Number of rows in the image. | integer |
satellite_azimuth | Spacecraft off track pointing direction, in degrees (0-360). | float |
satellite_id | Globally unique satellite identifier. | string |
strip_id | The unique identifier of the image stripe that the item came from. | string |
sun_azimuth | The angle of the sun, as seen by the observer, measured clockwise from the north (0 - 360). | float |
sun_elevation | The angle of the sun above the horizon (0 - 90). | double |
updated | Timestamp that the item record was last updated. | datetime |
view_angle | The satellite's across-track, off-nadir viewing angle. Positive numbers denote east, negative numbers denote west (-25 - +25). | double |
