<p class=MsoNormal style='margin-bottom:12.0pt'>Hi All,<br>
<br>
I am interesting too... I am considering PostGIS+WKTRaster instead of Oracle
GeoRaster... but for that can happen, Postgresql must be able of managing some
simple tables of 30+M (Millions) rows plus a lot of Rasters of 16GB each...
(16GB not compress data... so are huge images !). Each query (simple look up)
must response in a fraction of second....<br>
<br>
any successful case ?<br>
<br>
Thanks !<br>

to all:<br>
I am working in a project where they are managed more than 20 geoespatials
thematics. Each thematic one has a considerable volume of since information it
is of the whole country (I am speaking of a lot more than a million of
records). In the project we need to make (mostly) intersection consultations
keeping in mind literal attributes.<br>
I need to know the experience of somebody in a project of this span and if
PostGIS would present some limitation therewith.</span><o:p></o:p></p>
