Thanks @awongel! Looks great. I have two suggestions / requests:

1. Could you remove the Saudia Arabia example? The example got quite long and to me it didn't add too many new insights.

2. Do you have a comparison of the convert_csv() output before and after? That would make it easier to see whether the changes are plausible. Just a graphic + code snippet would be helpful.

Why was this change necessary?

Hi @fneum!

1. I had discussed with @euronion what we should add and felt that a second location would be useful to show that it works more generally than in a single location. If you think it's too much, I don't mind removing it again.

2. Since I replaced the calculation, would you suggest to keep the previous way of calculating it somewhere in the code? I wanted to avoid that. Or save the old result somewhere, but then you can't immediately see how it was calculated.

The change in the gis.py file was needed for the sarah data part of the example, which wouldn't run for me otherwise. Happy to remove if you can confirm this is not needed.
