Hi agin<br><br>Surely I did not mean to drop Shapefile support ! We must let the user choose. But now, as ESRI Shapefile is the simplest/default way (yet limited) to create/edit layers, we "force" the users to use it, which I dislike for reasons written previously.<br>
I think sqlite could be a great alternative. It has some limitations, but improves as time passes. We "just" need to modify QGIS tools to deal with sqlite file more smoothly as discussed before.<br><br>Regards<br>

Hi,<br>
Try-ing to supporto esri arcgis will introduce other and bigger problems.<br>
<br>
We have many trouble due to the convention of esri for the hole that<br>
are touching the boundary of a polygon.<br>
<br>
The esri product will trasform this in a not OGC compatibile structure.<br>
That on a OGC system is defined Invalid.<br>
So when a dataset with hole is touched from a esri arcgis it could<br>
became invalid for OGC.<br>
<br>
This is so a problem for us that we fund a change to postgis to have a<br>
ST_IsValid with a flag for compatibily with esri gemetries.<br>
<br>
QGIS is absolutely unuseful try to follow Arcgis if QGIS himself also<br>
don't support this different structure of polygons with hole on<br>
boundaries.<br>
<br>
Regards,<br>
