Okay, probably wrong forum, old post, etc., but it got me to thinking...

Why can't Maemo Mapper generate tiles from local vector data on the fly? I mean, basic vector data for a whole lotta' places is in the Mb range, not Gb. Ideally, mapper would have a configurable switch that just says "generate missing tiles." When you get to an area/zoom where tiles aren't cached, and you can't download the tile from a repository (offline), it just makes the tile on the fly from the local vector data. It can't be THAT hard. Even better (feature creep here) that vector data could also be used for locally-calculated routes.

On a more basic level, how about having a "local repository" in Mapper that is just a separate program that generates tiles on the fly. If you want tile X, generate it from whatever vector data is cached. OSM data is getting to be good enough for this now, so licensing costs are nil.

Why not? It would be the best of both...
