Pre-Render Great Britain Only

Question

Hi :)

My server has been pre-rendering tiles for awhile now.

When i setup my server i only downloaded the Great Britain Map since this is all that is required.

I started the pre-rendering process via the following command

"render_list -m default -a -z 0 -Z 15 --num-threads=12"

After some research i believe this is not ideal, so my question is how would i pre-render the whole of Great Britain to a zoom level of 18?

Accepted Answer

I use render_list_geo.pl. For zoom 1-12, the actual script that I run from cron is:

PATH=/home/renderaccount/bin:/home/renderaccount/.local/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
/home/renderaccount/src/render_list_geo.pl/render_list_geo.pl -n 1 -z 1 -Z 12 -x -9.5 -X 2.72 -y 49.39 -Y 61.26 -m ajt

If you want to pre-render everything once you'd probably want more threads, and you will want to keep an eye on memory usage, as there have been reports of this sort of "pre-render everything" approach having problems with that. Rendering everything to Z18 will get you a lot of tiles - if you want that amount of data offline (or able to be statically served) I might be tempted to look at another option for serving data, depending on what your goal is.
