[Freegis-list] vmap copyright

[Benoit Véler]

Hello,

         I am finishing a project with some vmap0 data, and I'm begining to 
have an awfull doubt : are these data really free of copyright ?
         I have downloaded the file V0eur at the adress :

         http://geoengine.nima.mil/ftpdir/archive/vpf_data/

         I have made two type of operations on this data :

         * extraction of specific areas (covering several countries),
         * modification of both vector and attributes files.

         From that point, I used to consider that these database could be 
considered as my own one, and I planned to resell it an a web site.
         But when I read the two sources here :

         http://intevation.de/pipermail/freegis-list/2001-January/000232.html

         and

         http://www.maproom.psu.edu/dcw/faq/ques1.html

         I am becoming really doubtfull... Can anybody give me his opinion 
on this pb, or do you know a place where I could have the information for 
sure ?...

         Best regards,

         Ben.
