I have heard rumours that Ordnance Survey are going
to drop NTF, I hope its true, but it could be wishfull
thinking. Otherwise I'll have to agree with Richard...

.....an NTF reader would be very useful, a godsend even,

In the back of my OS catelogue is a great long list of systems
suppliers who claim their systems will import NTF. Its quite
long but a few names look familiar eg

ESRI (UK)
Intergraph(UK)ltd
Moss Systems
Smallworld
Tydac

about 70 in all, and I guess most of these would be capable
of converting it into something sensible. I expect that you
have to buy the NTF reader as an add on (expensive) module.

People who need to use OS data, particularly vector data,
should be aware that it has some problems as it is currently
not sold as a GIS product, it is really for mapping (ie pictures)
hence there can be serious problems with connectivity, closed
polygons etc. At least they have recognised this and are making
plans to upgrade the data.

The address is
	Ordnance Survey
	Romsey Road
	Maybush
	Southampton
	SO9 4DH
	UK
	tel (UK) 01703 792773
        fax (UK) 01703 792324

no email as far as I know, I don't know who owns the NTF format
it might be public domain.
