Data sources and licences
AiroSignal reads public tender notices, project registers and news. This page lists each source, the licence it is published under and the attribution that goes with it. Every item in the briefing, on the dashboard and on the airport pages names its source.
How we use sources
- For each item we keep the title, a short description, the buyer, the value and deadline where the source gives them, and a link to the source. For news found through Google News we keep the headline, the publisher and a link.
- Titles and summaries in English are our own rewrites of the source text. The notice at the source is the authoritative version.
- Where a publisher prescribes a licence or an attribution text, it is quoted below as published. Where we have not established a licence, the entry says “Terms of the publisher” and the publisher’s own terms apply.
- AiroSignal is not affiliated with, or endorsed by, any of these publishers.
- To report a mistake or ask for an item to be removed, write to info@airosignal.com.
