Can any of you suggest a nice tutorial or something for rendering maps for self-hosting at much higher zoom levels? Many of these examples are for larger areas where zoom level 10 is sufficient, but I make hobby maps of mountain bike / hiking trails where the displayed area is only ~10km wide at the most with lots of fine detail. Thus, my maps tend to be shown at zoom levels 12-18, which is much higher than any of th…
FWIW I generated all the tiles up to zoom 18 for France (which is the best mapped country as far as OSM go), it represented about 300 GB of data.
You will need a big SSD, 16 GB ram for a big country, 32 GB for Europe, I think you can do the world with 64 GB but ofc more is always better. Count a few weeks to generate everything, probably less if you have a very good computer / server (mine was quite old, 2012ish I think).
