seems like openair got removed here by mistake?

[GliderGeek]

yes that is correct, will fix that in separate commit

Can someone help out on checking whether these new airspace files are handled correctly?
I currently dont have a local installation on which this can be tested.

From @TobiasLohner in #538:

There are a few things to consider when updating airspaces:

• Some of the airspace files contain unknown or wrong airspace class identifiers. This could possibly clutter the map when rendering (e.g. a FIR denoted as class A)
• SkyLines uses the gdal/ogr openair/sua parser which is not as robust as XCSoar's. Some files need manual editing before importing.
• Some airspace files contain country borders which shouldn't be imported as well. See https://github.com/skylines-project/skylines/blob/master/mapserver/airspace/airspace_blacklist.txt for some examples. This needs manual checking before import.

I recommend to test every single new airspace flie on a QA system (e.g. your local SkyLines installation).

unfortunately I don't have the airspace rendering code setup locally either which is why I haven't merged this yet... 😞

filetype was restored

French link is already broken again, current one is http://soaringweb.org/Airspace/FR/170922__AIRSPACE_France_2017-08-17.txt

Finally managed to get this done! 🎉

I've updated some more airspaces and rebased/updated the PR :)

[GliderGeek]

Awesome stuff @Turbo87! Did you get the mapserver running locally?

[Turbo87]

Nope, but I broke prod for a few hours 🙈

[GliderGeek]

ouch. any idea how we could get this thing working / ask someone who can guide us in the right direction?

[Turbo87]

The thing that broke was actually not related to the airspace (except for Belgium), it was some MapServer update that broke the airfield rendering (see #770)
