Image Registration of Sentinel-1 and Sentinel-2 products

[FedericoF]

@charlesbrincat: do you mean snapping the Sentinel-1 pixel grid to the Sentinel-2 pixel grid?
Have a look at this graph to preprocess Sentinel-1 GRDH data and snap the grid to the Sentinel-2 one:

Sentinel-1 GRD preprocessing graph

Standard workflow for the preprocessing of Sentinel-1 GRDH data. The GPF graph executes a Sentinel-1 GRDH preprocessing workflow that consists of seven processing steps, applying a series of standard corrections: Apply Orbit File Thermal Noise Removal Border Noise Removal Calibration Speckle filtering (optional) Range Doppler Terrain Correction Conversion to dB Sentinel-1 GRD products can be spatially coregistered to Sentinel-2 MSI data grids, in order to promote the use of satellite virtual …
