PSScene4Band

PlanetScope 4-band multispectral basic and orthorectified scenes. This data set includes imagery from all PlanetScope sensors. All PSScene4Band items have a corresponding PSScene3Band 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.

Product band order:

• Band 1 = Blue
• Band 2 = Green
• Band 3 = Red
• Band 4 = Near-infrared

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_pixel	Percentage of pixels that may have errors. Represented spatially in the UDM.	double
clear_confidence_percent	Percentage value: per-pixel algorithmic confidence in 'clear' classification.	int [0-100]
clear_percent	Percent of clear values in dataset. Clear values represents scene content areas (non-blackfilled) that are deemed to be not impacted by cloud, haze, shadow, or snow.	int [0-100]
cloud_cover	Ratio of the area covered by clouds to that which is uncovered.	double
cloud_percent	Percent of cloud values in dataset. Cloud values represent scene content areas (non-blackfilled) that contain opaque clouds which prevent reliable interpretation of the land cover content.	int [0-100]
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
heavy_haze_percent	Percent of heavy haze values in dataset. Heavy haze values represent scene content areas (non-blackfilled) that contain thin, low-altitude clouds, higher altitude cirrus clouds, and soot and dust which allow fair recognition of land cover features, but that do not have reliable interpretation of the radiometry or surface reflectance.	int [0-100]
instrument	Name of the satellite instrument used to collect the image.	string
item_type	Name of the item type.	string
light_haze_percent	Percent of light haze values in dataset. Light haze values represent scene content areas (non-blackfilled) that contain thin, low-altitude clouds, higher altitude cirrus clouds, and soot and dust which allow reliable recognition of land cover features, and that have up to +/-10% uncertainty on commonly used indices (EVI and NDWI).	int [0-100]
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. PSScene4Band items 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: sun altitude greater than or equal to 10 degrees, off nadir view angle less than 20 degrees, and saturated pixels fewer than 20%. If the image does not meet these criteria it is considered "test" quality.	string
rows	Number of rows in the image.	integer
satellite_id	Globally unique satellite identifier.	string
shadow_percent	Percent of shadow values in dataset. Shadow values represent scene content areas (non-blackfilled) that are not fully exposed to the solar illumination as a result of atmospheric transmission losses due to cloud, haze, soot and dust, and therefore do not allow for reliable interpretation of the radiometry or surface reflectance.	int [0-100]
snow_ice_percent	Percent of snow and ice values in dataset. Snow_ice values represent scene content areas (non-blackfilled) that are hidden below snow or ice.	int [0-100]
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).	double
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 off-nadir viewing angle. The value is always positive (0 - 90).	double
visible_confidence_percent	Visible values represent the fraction of the scene content (excluding the portion of the image which contains blackfill) which is comprised of clear, light haze, shadow, snow/ice categories, and is given as a percentage ranging from zero to one hundred.	int [0-100]
visible_percent	Average of confidence percent for clear_percent, light_haze_percent, shadow_percent and snow_ice_percent	int [0-100]
