I am new to snap. I have downloaded sentinel 1 image from ESA. I have performed radiometric cal-liberation as well as speckle filtering. After that, when I tried to perform terrain correction, the processing was completed within few seconds and the output obtained is a blank image as shown below.

enter image description here

Can anyone please help me out in this matter?

    If no elevation information is available, Terrain Correction might produce an empty output. There can be several reasons for that: 1) Your data is located outside 60°N or south. SRTM data only covers latitudes within: radiomobile.pe1mew.nl/images/srtm_covmap_hi.jpg 2) Your SNAP version is outdated and uses a wrong link to search for DEM data. 3) Your Firewall prevents SNAP from downloading the elevation data. – AndyB Jan 8 at 18:27
