OpenStreetMap
It looks like all 3 maps to a great job of mapping the area...
I noticed that Mapnik got the Bastion Street Bridge right. cool.
and osmarender got the International Hostel in there right. Cool.
and the Cycle map got the Bike shop in there right. Cool.
Fortunately over the next few months, i'll be learning how to configure my own rendering, when i use the SVG file. (I think its a matter of including some lines of code, to get more things added) So when they show up in book form, it would be nice to have it the 'most right' as possible.
So i think my example is pritty good to show what shows up on each map, to perhaps remind some people that the OSM database can contain TONNES of info.. but it's doesnt all need to be rendered. .... so it just depends on who will be using the map. :)
P.S. does anyone happen to know if someone has already started a planet sized map of just the SRTM topo data? ... IMG files just like the ones Computerteddy has? .. so it's 1 degree x 1 degree tiles, done to the standard zoom levels.
Im planning on starting over on the West coast of Vancouver Island, and working my way across... but would be nice if someone else has already done the autoscript for it. Thanks.

correction
"srtm2osm command line for corresponding elevation contour tiles. The tile number of the topo tiles is the tile number for the corresponding map tiles with the leading 6 replaced by 5. Thus, name clashes are avoided."
from http://touren.mospace.de/kachel.html (the IMG tile calculator says that it already exists... just replace the '6' with a '5' and you get the SRTM topo IMG file... cool.

I don't believe anyone is serving contours tiles for the whole planet at the moment - the size of the database and tile cache is very large for the whole planet and exactly how you render them depends a bit on the use you're going to put them to. For example, the cycle map is mostly concerned with the flatter areas whereas the piste map is of most use in very mountainous terrain - rendering the piste map with the same settings as the cycle map would result in the contours being unreadably close together.

That being said.... doesnt that mean that we can have a planet size database for the cycle map.. and one for hiking... and one for driving? ... so that would be just 3 databases. I dont see any reason why anyone would want any more than just the 3 defult types. .. perhaps one for feet. ... then it would be 6 types. But i dont see any more types.
"would result in the contours being unreadably close together."
... the zoom level could fix that, right? .. just how it does on the Garmin map of srtm data.
