    I found this dataset first because I was searching for JSON file format:

    It seems to be a conversion of version 4 of this github repository, but I am running into a problem:

    I am trying to render polygon lines in such a way that only the front of the sphere/globe is showing, but some parts of the backside is also showing, I am not sure why this is, perhaps an issue with the input data ? or perhaps the conversion process ?
    or perhaps some issue with GLScene or OpenGL ?

    Correct video link will be:

    if google manages to process it.

    I had to cut something off at the end, some sensitive data was leaked :)


    I could try and read the dbf file to see if these backface culling problems are caused by the conversion, or if this is simply part of this dataset, and I will try and use version 5.
