I discovered Mapillary recently, and I'm rather impressed by how mature the solution is and how complete the image database is. I'm also very happy to see an open solution.
I'm wondering about the long-term survivability though: imagine a disaster scenario where, for example Mapillary is bought by a company who decides to stop providing the images/service. Would that mean that the whole set of images is lost?
Since images are CC-licences, someone else could use the images and build a similar service with the existing images, but this is assuming that someone has this set of images, i.e. that someone replicated it before the service is closed.
Hence my questions: can someone legally replicate the Mapillary image database? My understanding is that downloading individual images is OK but the 50,000 images limit for the "free" plan prevents one from replicating the images without paying. One would need at least a paid plan to do so. Is this understanding correct?
The obvious next question is: if it's possible, does someone already do so?
Thanks in advance,
