Airport Shops on OSM

Tallinn Airport is said to be the 'cosiest' airport in the world. If you search for that on Google they come up first. I noticed none of the shops or other amenities around the gates are marked in OSM.

I wrote some code to see if this was an issue at airports of a similar size or larger nearby in other EU countries. I got a lot of false-positives but this code might help anyone else looking to enrich the Airport metadata in OSM.

TLL is surrounded by dense urban areas and a major shopping mall so I built a polygon mask around the airport gates and counted the shops within it.

Airports that came back with no shops within their gate area mask where:
