Super-resolution Sentinel-2

Description

A processing block that creates a 10 m resolution for all the existing spectral bands within 20 m and 60 m resolutions by using a trained Convolutional Neural Network.

See this block on the marketplace.

How it works

This block works on a minimum image size of 192×192 pixels. This is equivalent to a minimum area of 4 km².

Parameter	Overview
`bbox`	array of integers / required if Required if `intersects` or `contains` aren't specified. A bounding box to use as an AOI. Will clip to scenes that intersect with this box.
`contains`	object / required if Required if `bbox` or `intersects` aren't specified. A GeoJSON geometry to use as an AOI. Will clip to scenes that fully cover this geometry.
`intersects`	object / required if Required if `bbox` or `contains` aren't specified. A GeoJSON geometry to use as an AOI. Will clip to scenes that intersect with this geometry.
`clip_to_aoi`	boolean / required Whether the specified AOI should be clipped before processing: `true` — The AOI should be clipped first. `false` — The full scene should be processed. The default value is `false`.
`copy_original_bands`	boolean / required If `true`, the original 1 m resolution band will also be included in the output image.

In the output file, all the spectral bands for 20 m and 60 m will be in 10 m spatial resolution.

Example

An example using the Sentinel-2 L1C (SAFE) block as a data source and then applying super-resolution clipped to the specific AOI.
