[OSM-legal-talk] Using OSM data, to generate game worlds. How does the license apply to projects like this?

[Kathleen Lu]

Hi Lucas,
I disagree with Christoph re the LIDAR survey. Under the Collective
Database Guideline
(https://wiki.osmfoundation.org/wiki/Licence/Community_Guidelines/Collective_Database_Guideline_Guideline),
if you use solely a non-OSM source for building heights (versus
improving OSM building heights data with LIDAR data), you do not need
to share back your height data source. Same with weather data.
Please note that opinions on this listserv are just that, opinions.
You do need to look at the Guidelines for yourself, and if your
situation is particularly complex, consult an attorney.
Best,
Kathleen
