wondering if there is something like a second planet next to the usual OSM planet, which could be used for testing, demonstrating, discussing mapping of complex objects and structures.
Sometimes I would like to say ‘Look there, there I sketched a railway station with new feature/tag x. Is that tagging okay?’. Or: ‘Look there, there you find all 123 variants for mapping bus stops. Choose the one you like most.’
A second usecase would be mapping just for fun, a future city for instance. A human made planet with lots of cool structures, sounds like kind of art (and could get less tech-savvy user groups interested in mapping).
It’s not really my topic, I’m too much of a realist for that and have created quite a few examples of in-depth tagging and special things I’ve come across in my immediate neighbourhood through intensive trial and error and self-checking.
But I have seen a bit of reading material for fictitious mapping over the time:
How not to do it in any case was discussed here: F wie Fake-Land... I think it’s done funny so far though and admire the energy the mapper has put into it, unfortunately in the wrong place.
