We will happy to contribute in any way. I'd read the thread on osgeo list, a little bit cloudy for me, but I'll expect it to be sunny very soon.<br>

Hi,<br>
<br>
We use TopoGeo_AddPolygon Function to fill our database, it works.<br>
Now we've got 500 000 faces, and adding new faces with this function<br>
is very slow.<br>
At the end our database will contain approximatly 1 million of<br>
faces, I stop data integration for the moment beacause it's too<br>
slow.<br>
<br>
Is there a new function version planned ?<br>
</blockquote>
No plans for a new function, but there's some analisys<br>
undergoing to find more about this exact problem.<br>
