I am trying to resample some bands from a Sentinel-3 SLSTR image (Level 1 product) to the spatial resolution of the coarser bands (i.e., bands S1 to S6 to the resolution of F1). As I would like to repeat this operation on several images, I started using the Graph Builder to perform a batch processing. So, I built a simple graph “Read - Resample - Write”. However, when I go to the resampling step in the graph, I cannot define the reference band for the resampling, in the option “By reference band from source product” (the selection ribbon remains empty).
When performed manually (Raster > Geometric > Resampling), out of graph builder, it works perfectly.
I tried on Linux and Mac, with SNAP 8.0. No difference!
I tried with reprojected products and the problem remains.
Am I missing something fundamental?
Thank you in advance for your help!
