Sentinel-2 and Sentinel-3 products can spread over several UTM zones. At the moment only one UTM zone can be specified for the product, having a product over several UTM zones is not supported.

 

Possible solutions

...

1. Re-project part of the product.

...

  • loss of data / modified images due to reproject
  • the user wouldn't know what is the reprojected zone potentially transformed from the tiles not transformed
  • User might not know which UTM zone to select

 

...

2. Open only the tiles which are over a selected UTM zone

...

  • Only one UTM zone can be displayed at a time
  • User might not know which UTM zone to select

 

...

3. Open granules which are on different UTM zones on different bands.

...

This would consist in using the multi-resolution change to assiciate an UTM zone for each granule.

  • No user choice before opening the product

If compatible with the SNAP product model, the last option is prefered.
