Hi!<br>
<br>
I can give you an indication about the distribution of tile requests by zoom<br>
levels on my hiking map server at <a href="http://wanderreitkarte.de" target="_blank">wanderreitkarte.de</a>.<br>
<br>
<=z8 z9 z10 z11 z12 z13 z14 z15 z16 z17 z18<br>
19% 3% 4% 5% 6% 10% 14% 18% 8% 5% 3%<br>
<br>
This told me that prerendering is worthwhile only up to up to z15.<br>
<br>
I also used to do a regional analysis which showed great differences in<br>
access frequency and density. But that distribution depends strongly on the<br>
purpose of your map - in my case it was well-known hiking and holiday<br>
regions. The only general rule is that ocean tiles are almost never<br>
accessed.<br>
<br>
If you are concerned about storage space, you have the option to do a lot of<br>
on-demand rendering and regularly delete tiles that are older than n days.<br>
But in my experience, tile storage growth slows down asymptotoically over<br>
time, so I never had to implement that.<br>
<br>
bye<br>
