Multimap Support for UK

[GoogleCodeExporter]

What new or enhanced feature are you proposing?

Support multimap.com tiles.  This is a great source of the UK's ordnance
survey data and I think it would be well used.  Here's an example of a
tile's url:

http://mc3.tiles-cdn.multimap.com/ptiles/map/mi932/16/031313/300012/313.png?clie
nt=public_api&service_seq=14458

and here's the page that included it:

http://www.multimap.com/maps/?qs=ox183lx&countryCode=GB#map=51.8049,-1.58323|14|
4&dp=os&bd=useful_information&loc=GB:51.80765:-1.63672:14|burford|Burford,%20Oxf
ordshire,%20England,%20OX18%204

What goal would this enhancement help you achieve?

Walking around Dorset referring to OS maps while on holiday!

Just realised that I didn't say please anywhere.  It wasn't meant to sound like
demands - was just answering the default questions!  I'll see if I can work out 
how
to add it myself but I'm not familiar with the code.  Thanks.

Hello Mike

Thank you for reporting this issue, I'm always looking for new map services to 
add.
See Issue 63 that was back when we added support for OpenStreetMap.

Now what we need to find out is the meaning of all the numbers, just like this 
london 
example of OpenStreetMap:
http://c.tile.openstreetmap.org/12/2046/1362.png
_--_://[server(a,b,c)].tile.openstreetmap.org/[zoom]/[x]/[y].png

I notice that in multimap the first number is the server and it goes from 0 to 3
we need to find the rest

Helder

Ok, I've been looking at the images by url in firefox's page info window but 
can't
work out a pattern yet.  Any other suggestions on how to work that out?

This page looks helpful.  Looks like someone has decoded the url for the same 
purpose
so it should be just what we need.  I'll see if I can make sense of it.

This is a better link as it is to the actual article rather than the archive.

It looks as if he has written some perl to do the job.  Although I don't write 
perl
or python the code looks simple enough to interpret - it just builds the url 
piece by
piece and the complicated bit seems to be that a range of zoom levels has an
associated string like "mi953".

The author says that the structure is very similar to Microsoft live if that 
helps at
all.
