    Hi,Someone can help me?,
    i’m a new user, and when I have tried to coregistrate two ERS images or 2 Sentinel1 images it gives me the following error:

    WARNING!!! coregistration of image 20160708 failed!!!!

    image 20160708 will be discarded: check manually!!!

    List of Images for which the coregistration failed:
    20160708
    No Temperature data found: generating a synthetic sinusoid

    synthetic temperatures written

    get_locality: could not dowload the locality!!

    get_timezone: could not dowload the timezone!!

    ————————————————————–
    TOPS POST COREGISTRATION:
    ————————————————————–

    tops_slave_proc(): No New Slaves to update. Exit.

    The coregistration failed for 1 images

    You can try to process them again with the update function
    after checking the images one by one and manually modifying the coregistration parameters

    The Processing concluded successfully, here a specific message:

    SLC data Preparation: job ended

    This is the example with Sentinel 1, but it also happen when I try to use ERS images. I’m studing Deception Island and I dont know if the external dem is the cause of the fault.
    that’s why I’m asking you, in search of more experienced help in sarproz world

    1. read the forum and search for similar questions. Here an example: https://www.sarproz.com/groups/sarproz-group/forum/topic/coregistration/

    2. for Sentinel, you can use the orbital approach: https://www.sarproz.com/groups/sarproz-group/forum/topic/new-update-in-sentinel-tops-module/

    However, your case may be challenging for the TOPS post-processing steps. Please give us an update here so that we can check how it goes.
