help about map URL settings (CloudMade map)

[Gabriele]

Hello all,

I'd like to use the Leaflet JS with CloudMade maps, but I need some
help :)
I don't understand something about the URL construction:
'http://{s}.tile.cloudmade.com/YOUR-API-KEY/997/256/{z}/{x}/{y}.png'
what are the numbers 997/256 ?

I read in the quick start guide "Next we'll create a tile layer to add
to our map, in this case it's a CloudMade tile layer with Fresh style.
Creating a tile layer usually involves setting the URL template for
the tile images (get yours at CloudMade), the attribution text and the
maximum zoom level of the layer:".
So I did register on CludMade, I have my API key , and would like to
use their map called Tourist (styleId=7 using their exemple). How do I
refer to the Tourist map if I use Leaflet JS ?

thank you !

In this case 997 is the style and 256 is the tile size (probably won't change that). So just replace 997 with the map style you prefer.

Thank you :)
I now noticed the number in the bottom-right corner of the map is the
same as in the Leaflet exemple.
Maybe it would be a good idea to emphasize it in the documentation.

Just for the help of other readers, can you give a pointer to where
the styles (997, etc.) are documented?

as well as the range of the random subdomain numbers in the template
(the s value) which I suppose we should be rotating through?

[Jason Sanford]

I'm not sure about a list of styles, but the tile URL scheme is documented here: http://developers.cloudmade.com/projects/tiles/documents

Thanks for the link, here is the info I got from there::

It seems they have just three subdomains (a, b and c) e.g.

http://b.tile.cloudmade.com/8ee2a50541944fb9bcedded5165f09d9/1/256/15/17599/10746.png

and here is the link to the style sheet explorer:

Hi Jason

I am also playing around with the example code which really is misleading. What I don't get in the CloudMade URL is the '{x}/{y}/{z}' section. I did some digging around and they say it's the x-tile, y-tile numbers and then we're given an equation to work these out which took me more than an hour because I don't know what lon_deg, lat_rad and ln(natural algorithm) is. And when I worked them out I still couldn't get the map to work.

Please help!!

Hello Siyabonga,

you can see a working exemple I just finished today here:
http://www.goldemotion.it/goldemotion-dove_leaflet.html

I used the "tourist map" (and I also updated the streets map in the OpenStreetMap project for the area shown in that website).

ciao

Yes, I have seen this article, which is very good.

But I would like to know what is going on with EPSG4326 mapping. WebMercator does not work for our applications. Leaflet supports EPSG 4326 CRS. But I get some funny things at zoom levels 0 and 1.
