Use S1-Tiling within PEPS

If you are allergic to the command line (that's a pity), you can use the on-demand processing features of PEPS, although it does not include the speckle filter yet. It's very simple.

  1. First, connect to PEPS (https://peps.cnes.fr)
  2. Select the "explore" function
  3. Query the catalogue to obtain the images you wish to process (don't forget to mention you want a GRD Sentinel-1 product). For each product that fits your criteria, click on the gearing icon
  4. go to the processing page (gearing icon, top-right)
  5. select Sentinel-1 ortho-rectification
  6. select every product and start processing
  7. just wait for a while
