<font face="arial" size=2>In fmrt files i am ask to provide several
fields for grass to be able to find the geometry and category
data.</font><br>
<br>
<font face="arial" size=2>Postgis stores in one column in my case
wkb_geometry, a string identifying at the same type the SRID, the
geometry type and the actual geometry in wkb, with a constrain at the end
that tell pgsql how this string is constructed (Am i
right?).</font></blockquote><br>
I don't think it is a string, I think it is a BLOB (a Binary Large
OBject) and PostgreSQL displays it as a string (with the help of
PostGIS). And where do you see this
"<font face="arial" size=2>constrain at the end that tell pgsql how
this string is constructed"?<br><br>
<blockquote type=cite class=cite cite>Has anyone build a protocol or sql
sentence to prepare a postgis table for the grass requiered format: ie
separate geometry from category with the same ID on both tables, and in
the geometry table separate the geometry from the geometry
type?</font></blockquote><br>
This might help:<br>
