The process upsamples the spatial resolution of the red, green, and blue (RGB) spectral bands in Pléiades and Pléiades Neo 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.
| Collection | Spatial resolution of input imagery | Spatial resolution of output imagery |
|---|---|---|
| Pléiades | 50 cm | 25 cm |
| Pléiades Neo | 30 cm | 10 cm |
Upsampling can be used as a preprocessing step before change detection, vegetation detection, infrastructure detection, fire risk estimation, and land use management.

Required parameters
Input imagery
You need to specify the STAC items you want to apply the process to.
Output title
You need to specify the title of the output objects. This title will be assigned to the resulting STAC item and STAC collection.
Use the upsampling-ns name ID for the processing API.
