I'm trying to put together some maps regarding flights between different countries, but want to be sure to avoid high conflict areas on these flights such as North Korea, Syria, etc.. I've been investigating the GeoGraphics function and it has features such as coastlines data, street data, elevation data, but as far as I'm aware there is no data for airspace. For landlocked countries, obviously the airspace ends at the border to the other country, but with countries on the coast there is usually several miles of ocean before their airspace ends. Where would I go about finding this data? I've found https://skyvector.com/ shows where airspace ends, but this is not in a programmable data format and I would have to go by hand and list all the coordinates. And help/guidance would be greatly appreciated!

Thanks in advance!
