It combines offline mapping, search, wiki backed POI and routing into a service I control and can use across my own network.
It “solves” the problem of me wanting to do exactly that, using a Raspberry pi, and does so in under half a gig of ram.
It’s not a product I made for anyone else; I’m sharing it because people asked me to share it (thus the all at once remote push to github btw; I had no intention of sharing this until Lemmy asked).
