Hello I want to use a SIG called grass under linux redhat6.1. This SIG can connect to postgresql to obtain table describing geographic object like sites, polugon etc... Unfortunately all this information are under oracle (I think it's a 7.0 release). Now I've telecharged the "oracle-odbc-0.0.2-1.i386.rpm" (it's a package containing a odbc driver to establish a connexion between a database under linux and a database under oracle), this one need another package " unixODBC-1_8_8.tar.gz" I've telecharged but it isn't very clear to connect postgresql to oracle. Does someone could help me? -- IMBERT Pascal INRA-Campus agronomique BP 709 97387 Kourou Tel direct:05-94-32-92-91 Tel standart:05-94-32-93-00 Fax:05-94-32-69-14
