Does anyone know how much disk space a map tile set of the whole world takes up? It obviously depends wholly on zoom levels, etc, but if anyone has done this themselves I'd love to hear more about their experience.
about 54 TB. But only about 2% of tiles have ever been seen. Each zoom level has 4 times as many tiles as the previous level and zoom level 18 (the highest) doesnt have a lot of data.
Quote: "OSM does NOT pre-render every tile. Pre-rendering all tiles would use around 54000GB of storage. As the following table shows, the majority of tiles are never viewed. In fact just 1.79% are viewed."
Those figures are about a year old, though it does give a newer figure for space used which is about 1200TB or 2.7% of the total size estimated.
