OSM Tile servers [1 Attachment]

They may be a bit different in view. Look at these two tiles.




The underlying data will be the same. Even OSM changed their schemes over time.


Best regards,

Can I have the files from your server go into the same directory as the files from OpenStreetMap.org?  In other words, are they the same and compatible tiles, just from a different server?


If that’s OK, then I assume I could have two different Map Tile sets configured into the same directory because it is really just one set of tiles.  So I can get slow delivery when I have the time, and “express delivery” when needed.  Am I still correct?

Thanks, Arnold, KQ6DI

Just thought I'd post an interesting comment from one of the OSM admin team:

So, if you're using OSM's main tile servers, please do NOT do massive
downloads of tiles.  We don't want APRSISCE/32 to be blocked for everyone.

If you want to download large areas of tiles for offline use, you can
set up a Configure / Map / Tile Set pointing to my current OSM tile
server.  It's slow, but it'll eventually deliver your tiles.

PS.  Note that my ports 6360 and 14160 current deliver OSM tiles from
b.tile.openstreetmap.org.  If you have a tileset specifying one of these
ports, please consider changing it to 14171 if you can stand the lag.
