Data product name and description

Pléiades Neo is a constellation of four identical, very high-resolution optical satellites launched in 2021 and 2022, developed by Airbus.

The Pléiades Neo satellite constellation will provide customers with 30cm panchromatic and 1.2m multispectral satellite imagery with six bands and will offer mono, stereo, and tri-stereo images for various mapping applications.

For more information; please check out documentation in the References section.

Pléiades NEO sensor spectral bands are described in the following table:

Spectral bands:
Spectral range (nm)
                

Spatial resolution (m)*
(Ground sampling distance)

Maximum image dimensions
(Swath width)
                

Notes

Panchromatic:
  • 450-800nm
0.3m

110km x 70km
14km at nadir
                

Viewing angle: ±52 degrees

Multispectral:

Deep Blue
  • 400 - 450
Blue
  • 450 - 520
Green
  • 530 - 590
Red
  • 620 - 690
Red-Edge
  • 700 - 750
Near Infrared
  • 770 - 880
1.2m

110km x 70km
14km at nadir
                

Viewing angle: ±52 degrees

* Resolution is always nadir position unless noted otherwise.

Pléiades Neo satellites always acquire images simultaneously in two modes:

  • Panchromatic: one band (black and white)
  • Multispectral: six bands (colour)

Panchromatic and Multispectral image products are co-registered (completely superimposable).

The geometric processing levels described in the following table.

Processing level Description/notes
Primary The Primary product is the processing level closest to the natural image acquired by the sensor. This product restores perfect collection conditions: the sensor is placed in rectilinear geometry, and the image is clear of all radiometric distortion.

Rational polynomial coefficients (RPC) and the sensor model are provided with the product to ensure full autonomy and simplicity of use.

Projected The Projected product is mapped on the Earth onto a projection system at a constant terrestrial altitude, with respect to the reference ellipsoid. By default, the ellipsoid and map projection is WGS84/UTM, and the altitude is the mean altitude computed over the image area. The user also has the choice to select a projection system on WGS84 from the many offered by Airbus Defence and Space Intelligence and to customise the altitude value.

Just like Primary images, data processed at projected level can be used for geometric modelling, orthorectification or 3D extraction, for example. This is possible thanks to the RPC model provided with the product.

Standard Ortho The Ortho product is a georeferenced image in Earth geometry, corrected from acquisition and terrain off-nadir effects. The Ortho product is produced as a standard, with fully automatic processing.

For each Geometric processing level users can select the spectral-band combination, radiometric processing level, bit-depth, and file format desired.

Distribution disk files

Pléiades Neo data sets are organized in a specific folder structure on disk. GDB uses this folder structure and the file names to identify the data product type. Therefore, to preserve compatibility with GDB, do not alter the folder structure and file names when copying and decompressing the data.

Pléiades Neo is distributed using DIMAP V2. The data directory also includes multispectral and panchromatic data. You can open the entire data set by selecting the DIM*.xml file.

Main file (select to open) name defined as:

DIM_PNEO3_yyyymmddhhmmsss_AAA-BB_CCC_xxxx_xxxxxx_x_*.XML

AAA: Product type
BB: Spectral processing
CCC:  Process level
xxxx_xxxxxx_x_*: Job ID

Returned data for supported format

Pléiades Neo data can be opened directly in its raw vendor format or imported into a PCIDSK (*.pix) file using the key file name (DIM*.xml). For optimal processing, use the PCIDSK format.

The following table describes the data structure after it is opened by GDB. Note that the Multispectral and panchromatic data must be opened separately.
