----------------------------Original message---------------------------- From : [log in to unmask] Has anybody out there used DCW (Digital Chart of the World) or know anything about the file formats the maps and vectors are stored in.It is produced by the U.S. Defence Mapping Agency - it comes in 4 Cd's with VPFview software. The fiormat is VPF - but what is VPF format ? The reason for my interest is that the digital data for DCW is royalty free and it would therefore be very useful for reproduction in G.I.S. applications. If anybody has info on VPF I would be very grateful By the way DCW costs only 200 pounds sterling and is available from : Chadwyk-Healey Ltd.
