Save S1 product to SAFE format


Is is possible with SNAP to save a Sentinel-1 processed product to SAFE format?

Let’s say I just ran the Apply-Orbit-File operator. How to export the result to SAFE format? Or to any format that Orfeo Toolbox (OTB) can read?


you can export sentinel 1A to geotiff


Not really since:

  • “GeoTIFF+XML” is limited to 4GB and Sentinel-1 images are often larger than 4GB
  • GeoTIFF-BigTIFF stores the metadata in a way that is not recognised by OTB


Why don’t you use the .img file within the .data directory of your processed scene? OTB can handle that


I agree. Output to Beam DIMAP produces SNAP conform data (metadata is preserved, no limit in size) which is basically in ENVI format. This can be read in almost any GIS, OTB included.


Thank you for you answers. The problem with Beam DIMAP is that OTB is not able to read a Sensor model from it.

I’m trying to run the code snippet shown here:

It works well on SAFE products, but on Beam DIMAP the sensor model is considered invalid (model->IsValidSensorModel() returns false).

Do you know any other format that would work to export a sensor model from SNAP to OTB?
