----------------------------Original message---------------------------- In response to the Etak request, you could try either Hunting Technical Services or the National Remote Sensing Centre. The latter are at Delta House, Southwood Crescent, Farnborough, Hampshire, GU14 0NL, UK. Tel 44 (0)1252 541464. Alternatively, you could break all long established precedents and try Bartholomew since we have a complete set of imagery and also an already digitised Arc/Info vector database of Greater London at 1:5000 scale. We are after all part of the same company as Etak! (News Corporation for those who don't know). Hope this helps, Tim Rideout Bartholomew 12 Duncan Street, Edinburgh, EH9 1TA, Scotland, Europe. email: [log in to unmask]
