hi all
anyone have try to make all tiles render, without we have to click
the
mapnik/map
we have full total planet for global, and wanna to make the tile
render, so everyone that come to new map, (never clicked before), can
see the map, without have to reset
can help?
and what will the total space used for this
[1] states that the average tile size of all tiles is 633 bytes and the
total number of tiles is 91,625,968,981. That comes to a grand total of
53 TB of diskspace. Not sure if this is practical.
To limit the diskusage you can symlink all ocean tiles. Given that
about 30% of the earth is not covered by water you would still need
about 16TB to keep all tiles.
The same pages says that on z18 only 0.9% of all tiles have ever been
viewed. You may want to decided to generate z17 and z18 only in specific
places, that will reduce diskspace by 75% also.
