There are some missing tiles at osmarender http://www.openstreetmap.org/?lat=14.6365&lon=121.1&zoom=14&layers=0B00FTF Checking the data layer, that data is there. cheers, maning -- |-|--| | __.-._ |"Ohhh.

The way I remember it is lines of *long*itude are all as *long* as each other, so they run North-South(-North) around the globe, and so measure how far East-West you are. Lines of latitude vary in size being a maximum at the equator and a minimum at the poles (so measure how far North or South you are). >From that I would be able to confirm that you are correct above.

The latitude goes from -90 at the south pole to 0 at the equator to +90 at the north pole, and the longitude -180 to +180. A box is most easily specified as 4 numbers, with the topmost latitude drawn at the top, the most eastern longitude to the left, etc.. Think of it in the context of a globe, or map, with those numbers written in the appropriate place on it. minlat is the minimum (ie lowest, southernmost) latitude (so the lowest in the group of 4, ie 25.5 in your example), maxlat the highest (56), and longitude works just the same. So to convert the above to a bbox gives you bbox(-132, 25.5, -67, 56) Does that clear it up a bit?

This is perfect,except which number is what? 56 -132 -67 25.5 So it would be great if it said which one is long vs lat ??? Which one is what? is long min 56 and max 25.5 or min 25.5 and max 56?

The number of tiles drops by a factor of 4 for each zoom so the above estimate becomes about ~1TB for all up to z15 and take something in the order of a month of CPU time. mod_tile not only servers the tiles but also ensures they are cached and rendered in real time when required. This avoids the need to pre-render tiles in many cases. Jon ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

As Dave said, you will need to edit the file, and read the bit at the bottom. Before you do though, here's some stuff to calculate. Each zoom level is (2^z)*(2^z) tiles in size. So if you want all the tiles, for all the zoom levels, calculate how many tiles is (2^18)*(2^18), plus (2^17)*(2^17), plus all the others, and how long you think it will take to generate them, and how much disk space.

You'll need to modify the script. There's a line where it says "Change the following for different bounding boxes and zoom levels" where it starts rendering areas. It starts out with the whole world up to zoom level 5. You'll need to decide what the maximum zoom level you want is. Each level is 4 times bigger than the last one, so to do everything up to zoom 7 is about 22 thousand tiles and everything up to zoom 12 is about 22 million. That will take up a lot of disk space and take a very long time to render, so you probably want to be more specific with the area to render.

This renders them on request if they haven't already been done. There are many millions of tiles on the tile server, taking up GBs of space. If you just want prerendered tiles then you'll need to modify the area being rendered by the generate_tiles script. It's currently hardcoded to render some cities at the bottom of the file.
