<p class=MsoNormal><span lang=EN-US>Dear List,<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>i’m Swiss and my English isn’t the
most best. Even, I will try the explain You my problem. Perhaps You will
understand </span><span lang=EN-US style='font-family:Wingdings'>J</span><span

<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>In Switzerland the parts of the country
were measured by different offices. The informations of the terrain (parcelles,
rows, lakes, jungle etc…) are exchanged by Interlis Files (*.itf).<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>With ogr2ogr this files can be imported
into a Postgres Database.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>When You import only one file, it’s
not a problem. Every Line, Point, Polygone and so on, has its own Feature-Id, which
can be linked with another feature.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US>I.e.: The geometry of a parcelle is linked
with his number.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>Now, when I would like add a second village
to my GIS, in the same Database, to be loaded in Mapserver with a mapfile layer…
the parcelle with the same Feature ID will appear twice… so the link to
the number of the parcelle is wrong…<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>What I made in a first time: after have
imported the first village, I add to the primary and foreign keys, which I
really I’m going to use in my GIS a Char (‘a’ in example)…
by using PostgreSQL… only after I imported the second file. This is a
solution which works, but not for long time </span><span lang=EN-US

<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>I asked me, or better: I ask You, if there
isn’t a mechanism in PostGIS or PostgreSQL which is specially implemented
for this kind of collage… Some kind of namespaces or… I don’t
know… You understand =-) ?<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>Thänk You very much for Your help.<o:p></o:p></span></p>
