duplicate iso code in iran's country map

[MammadTavakoli]

in iran GitHub GeoJSON Content two IR-07 (for tehran and alborz) but thy are difrence.

also there is not IR-09 that one of then can replace with it

That's interesting! I think that data comes from our upstream source. Do you know which one is the incorrect ISO code? It can probably be re-mapped (corrected) with a cell in the Jupyter notebook that generates the GeoJSON. Here's a blog explaining some of that.

It appears IR-09 is Khorāsān-e Raẕavī so I'm not sure how this all fits together. IR-07 is Fārs province, and Tehran / Alborz are IR-23 and IR-30, according to a casual search. I'm not sure what the heck is going on here, but obviously they need to be the correct ISO codes, or people won't be able to map things accurately.

@rusackas , the correct iso code is here, but they are used other code for this that compactly different with what Wikipedia said.

The IR-07 in iran GitHub GeoJSON Content used for Tehran and Alborz.
It is bather to replace one of the IR-07 code for Alborzwith IR-09 the problem solve.

If anyone is willing/able to address this, here's a blog on how to update the maps (using the Jupiter notebook) to fix this sort of thing: https://preset.io/blog/how-and-when-and-why-to-update-apache-supersets-country-maps/
