Pleiades

Pleiades is a satellite constellation providing very high-resolution optical imagery and is owned by Airbus. It is now possible to purchase, order and access Pleiades data using Sentinel Hub (SH).

About Pleiades data

Mission information

Pléiades is composed of two twin satellites orbiting the Earth 180° apart. The satellites deliver 0.5 m optical imagery and offer a daily revisit capability to any point on the globe. Data acquisition must be tasked, data is not acquired systematically. Pleiades' satellites share the orbit with SPOT satellites, which makes it possible to combine the data form both sources.

The Pléiades data with its high spatial resolution is suitable for a range of remote sensing applications such as vegetation monitoring, precise mapping, risk and disaster management.

Purchasing Pleiades data

The process of purchasing of Pleiades data in Sentinel Hub goes as follows:

  • Check the pricing and conditions. If you would like to buy bigger area send us an e-mail and we will prepare a custom offer.
  • Go to the "Billing" section in your SH Dashboard and buy the Airbus Pleiades plan.
  • Once the payment is processed, we will send you a confirmation and you will be able to proceed with ordering the data.

Ordering Pleiades data

To order Pleiades data, please use our Third Party Import Data API. Please note that you can only order the already acquired data, while tasking your own Pleiades data acquisitions is not currently possible through Sentinel Hub.

SH uses the following settings when ordering Pleiades data:

Provider's parameter / toolThe values used by SH for ordering
product typebundle
radiometric processingREFLECTANCE
crsUTM zone corresponding to user defined bounds
processing levelSENSOR or ALBUM

More information:

Note: If you would need any other Pleiades product, please contact us.

Once your order is successfully finished the ordered data will be available in one of your BYOC collections and ready to be used. To access the data you will need the id of this collection.

Accessing Pleiades data

Accessing of the PlanetScope data is similar to accessing any other BYOC data. All processing and filtering options listed there can be used. However, the settings specific for accessing of Pleiades data are listed below.

Use the id of the BYOC collection into which your Pleiades data was delivered as a value of parameter input.data.type in the process API requests. See BYOC data access for more information.

Available Bands and Data

This chapter will explain the bands and data which can be set in the evalscript input object: Any string listed in the column Name can be an element of the input.bands array in your evalscript.

NameDescriptionResolution
B0Blue, 430-550 nm2m
B1Green, 490-610 nm2m
B2Red, 600-720 nm2m
B3Near Infrared, 750-950 nm2m
PANPanchromatic, 480-830 nm0.5m

Units

The data values for each band in your custom script are presented in the units as specified here. In case more than one unit is available for a given band, you may optionally set the value of input.units in your evalscript setup function to one of the values in the Sentinel Hub Units column. Doing so will present data in that unit. The Sentinel Hub units parameter combines the physical quantity and corresponding units of measurement values. As such, some names more closely resemble physical quantities, others resemble units of measurement.

The Source Format specifies how and with what precision the digital numbers (DN) from which the unit is derived are encoded. Bands requested in DN units contain the pixel values which are the result of ordering and preprocessing the data as explained in the chapter Ordering Pleiades data. Note that resampling may produce interpolated values. DN is also used whenever a band is derived computationally (like dataMask); such bands can be identified by having DN units and N/A source format.

For Pleiades bands, DN are the default and only unit. Reflectance values can be obtained for optical and panchromatic bands using the simple formula: reflectance = DN / 10000.

The Typical Range indicates what values are common for a given band and unit, however outliers can be expected.
