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.

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

Input data items must be added to storage in 2023 or later.
