<P><FONT SIZE=2>Hi, for an explanation look at <A HREF="http://gis.washington.edu/esrm250/lessons/create_f_layers/exercise/index.html" TARGET="_blank">http://gis.washington.edu/esrm250/lessons/create_f_layers/exercise/index.html</A> and search for auto-complete</FONT></P>
<P><FONT SIZE=2>On PostGIS we normally implement the functionality in an auto-clip function in either the service layer of the web-application or in the database. It is a rule about "no overlap" you would want to enforce on a layer/feature type independently of the client.</FONT></P>
<P><FONT SIZE=2>However in some cases it a nice functionality when creating adjacent features. In SpatialEdit we have implemented it a little different as you can clip a feature with any other feature. It does not provide the same degree of automation, but allows you to clip with any feature from any layer outside the concept of Map Topology. </FONT></P>
<P><FONT SIZE=2>Best regards</FONT>
