Hi Andreass,<br>I alsa expect the default being 0, not 100 as it was. It's a fresh new install from OSGeo4w... I don't know if it's built with this default, could it be?<br><br>Anyway, lat/lon is used by my customer to edit POI layers for GPS, so the default deegrees are ok. Anyway, as you, in my comon experience (soil science) meters/projected SRSs are more absolutely more usual...<br>

Hi Giovanni,<br>
<br>
Per default, QGIS disables snapping by setting the tolerance to 0. In my<br>
experience QGIS behaves as expected and I wouldn't want to change its<br>
behavior.<br>
<br>
Somehow you might have set the snapping settings before? Are you sure it<br>
is not your (or your customers) fault?<br>
<br>
Also make sure that you map units are correctly set. People often forget<br>
to set them to meters. In my experience the majority of the (large scale)<br>
GIS projects are based on meters, not on degrees. Only a few small scale<br>
(or GIS projects of global scope) are usually based on deegrees.<br>
<br>
