If you want to just prerender, render_list is pretty simple to use. I usually do something like this:
render_list -v --all -n 20 --socket=/var/run/renderd/renderd.sock --min-zoom=0 --max-zoom=13 with -n being the number of cores you have. render_expired usually takes a list of tiles you want to render. ie. echo "10/1002/649" | render_expired -v -n 20 --socket=/var/run/renderd/renderd.sock --map=default --min-zoom=10 --max-zoom=13 --delete-from=10 you can use omsosis to download a change set and process it via osm2pgsql. You can use osm2pgsql to generate a list of expired tiles. Have a look at this: http://wiki.openstreetmap.org/wiki/Tile_expire_methods its a lot less time consuming to only rerender the tiles that have changed. Z10-15 are pretty CPU and time intensive in my experience.. z0-9 can be rendered in a few hours depending on your hardware. just my 2 cents. -- Samir On Wed, Dec 8, 2010 at 3:41 AM, Frederik Ramm <[email protected]> wrote: > Hi, > > On 12/08/10 09:39, Peter Körner wrote: >>> >>> I'd like to pre-render the zooms 0 to 14 or 15 and render on-demand the >>> higher zooms. >> >> Are you using tirex?
