[OSM-legal-talk] distance calculations

[matthias.straetling at buerotiger.de]

Dear IANALs,

I'm sorry to ask an additional question.

A while ago, I've listened to a talk about navigation of pupils from their home to the school - it was used to decide whether the pupil gets a free bus ticket or not.

The distance calculation was done by a land registry office, which didn't have a route-able road & path network, but had trust in the OSM data, since they inspected it for quite a while. For completeness, they've used their own housing and school locations, but didn't use any from OSM.

They routed from the pupil's house to the school on the OSM network. Of course, the results were released in public.
Do such distance calculations also trigger share-alike on the non-free data (here: schools & houses).

Regards,
Matthias
