    Hi,
    How to import sentinel 1A data?

    My soure image is TIFF format,it’s in a folder called ”S1A_IW_SLC__1SDV_20170319T073316_20170319T073344_015758_019F18_2569” ,its original name is s1a-iw1-slc-vv-20170420t045223-20170420t045248-016223-01ad22-004.tiff .

    So I put image in folder “SLC” : /C/Users/Krzychu/Desktop/SLC/S1A_IW_SLC__1SDV_20170319T073316_20170319T073344_015758_019F18_2569/,and set the working directory.But it didn’t work .

    First identified directory: /C/Users/Krzychu/Desktop/SLC/S1A_IW_SLC__1SDV_20170319T073316_20170319T073344_015758_019F18_2569

    get_dir_slc: no known format recognized in directory /C/Users/Krzychu/Desktop/SLC/
    I don’t know how to solve this problem.

    Thanks.

    All satellite data come in a specific format.
    The format is not only about the file containing the data.
    Format may include also subdirectories and additional meta data.
    You should never touch such structure and never separate original files.
    In particular Sentinel data are organized in directories whose name terminates with .SAFE
    and they have subdirectories called “annotation”, “measurement”, “support”, …
    If you are working in linux, you can place tar files in the SLC folder, the sw will do the rest.
    If you are working in windows, extract the data in the SLC folder preserving the directory structure.
    best

    I do not know if I understood correctly.
    I work in windows. So I do not have to create “SLC” directories. All I’m putting in to directory, whose name terminates with .SAFE ?
    I did that and it didn’t work.

    What are corrently directories structure?

      when you download your Sentinel SLCs, create your own directory for data, like, “TEST”, then inside this folder create a new one called “SLC”, and put either all the .zip files of Sentinel inside, or the zipped folders, ended in “.SAFE” inside the SLC folder. then read the “TEST” folder in sarproz.
