I got the UK from Sheffield South on a set of 6 CD ROMs a couple of years ago - about Â£120. Fantastic bit of kit, but I have no idea whether they are available through the QM. Memory map at http://www.memory-map.co.uk/
Does fly throughs of planned routes and 3D terrain images. Very Gucci.
You can get digital mapping on Disk through the correct military channels. It's designed for use on BOWMAN so get yourself on an Application Specialist Course where you will learn all about electronic mapping.
