There is a quite comprehensive list of street names included in the data, but it 
needs converting to something a little more useful. Currently it is a 'colon 
separated list'. I hope to have a database view of it once the raster stuff is 
running.

One problem I'm battling is the inconsistencies in use of upper and lower case 
in file names. The reference files use upper case, but the raster images have 
blocks with lower case names. A bit of a pain when using Linux - obviosuly OS is 
still windows based :(
