Upsampling

An algorithm that improves the spatial resolution of RGB bands in Pléiades, Pléiades Neo, or Maxar imagery.


Overview

The process upsamples the spatial resolution of the red, green, and blue (RGB) spectral bands in Pléiades, Pléiades Neo, or Maxar imagery using convolutional neural networks.

The result is a GeoTIFF file with an upsampled spatial resolution. The upsampled spatial resolution depends on the collection the input imagery is from.

CollectionInput resolutionOutput resolution
Pléiades50 cm25 cm
Pléiades Neo30 cm10 cm
Maxar30 cm10 cm

Upsampling can be used as a preprocessing step before change detection, vegetation detection, infrastructure detection, fire risk estimation, and land use management.

Performance

To get the best results, use pansharpened data products. If you’re working with multispectral data from Pléiades or Pléiades Neo, pansharpen it before upsampling.

Requirements for input imagery

The data item must be a supported data product:

  • Pléiades tasking: Custom, of the display radiometric processing level, with the following spectral bands combinations:
    • 3-band: pansharpened true color (RGB)
    • 4-band: pansharpened (RGB and NIR)
    • 4-band: multispectral (RGB and NIR)
    • Bundle: 1 panchromatic and 4 multispectral bands (RGB and NIR)
  • Pléiades Neo tasking: Custom, of the display radiometric processing level, with the following spectral bands combinations:
    • 3-band: pansharpened true color (RGB)
    • 4-band: pansharpened (RGB and NIR)
    • 4-band: multispectral (RGB and NIR)
    • 6-band: pansharpened (deep blue, RGB, red edge, and NIR)
