Voici les reponses que j'ai eu concernant le base de donnees mondiale VMAP (DCW).
Merci a tous ceux qui m'ont repondu .

////////////////

The US Geological Survey markets the DCW for the National Imagery and
Mapping Agency.This version would be in tile format and not Arc converted.
This library has edition 003 (1997), so I would hope that the national
boundaries would be more up-to-date than on our Web site (which is based on
the 1992 edition). It can be ordered from them for and is identified
as Vector Map (VMAP) Level 0/Digital Chart of the World, 01-VMAP. The Web
page is at http://mapping.usgs.gov/mac/isb/pubs/forms/nimapl.html

The Arc version DCW, in tile format, was produced by ESRI using 1992 data.
I do not know if ESRI has an updated versions available. I have been told
that it costs about . ESRI has an office in Meudon, France and their
email is rgal@texte-a-enlever.esrifrance.fr with a Web site at www.esrifrance.fr.

The DCW on our Web page is the ESRI version that personnel, no longer
employed by the University, modified to allow downloading by individual
country. I expect that should you buy either versions of the DCW mentioned
above that you would have to build your areas from the tiles.
