I'm trying to compile a list of free and inexpensive sources of Ordnance Survey-based digital mapping as an alternative to the expensive products marketed by companies such as MemoryMap, Anquet etc.
I'm aware of two subscription services:
Ordnance Survey Getamap
Route Grough http://route.grough.co.uk/
and one free service (donations accepted):
Are there any others?
Best wishes for Christmas and the New Year
