Has there been any progress on this?

That is good progress, thank you for updating us.

Status update: acc to LFV, who publishes the Swedish AIP, soaring areas should be published in the AIP in ENR 5.5. It is the Transportation Agency who "owns" this chapter, so I have resent my request to them (and LFV is investigating on their side too). We'll see if/what they answer. The main drawback is that ENR 5.5 is probably not automatically parseable as it looks currently.

Thank you. The best way (as you say) will be able to get the areas officially published, then we can incorporate and maintain them to a good standard. If your enquiry is not successful we will need to revisit this.

We cannot accept files such as the ones on that page, that include disclaimers absolving the authors of any accuracy requirements.
