Is there a tool to merge two S1 IW products along a track before processing? Basically we need to merge the geotiff files and the XML files to make a new product. WE don’t actually use SNAP for InSAR processing so am looking for a tool that provides the original format on output.
We don’t have anything that will write to the Sentinel-1 SAFE format.
You can use the S-1 Slice Assembly tool to concatenate products together but you will need to save as DIMAP or BigTiff.
There is a command called
gpt SliceAssembly
that looks promising. I tried to run it from the SNAP GIU and there was a Geotiff-XML output option but the job failed at the 4 Gbyte limit. What we really need is a way to do this on a pair of along-track XML and geotiff files. The most difficult part is to merge the two XML files. We don’t need to rebuild all the directory structure of the SAFE product.
Thanks,
David
