Hi,<br>this is the kind of question I face when in my lectures evangelising OS GIS.<br>ArcGIS has many tools, though some prefer to call it a deluge of tools, which almost distance the user from understanding the concept of GIS.<br><br>Auto Complete Polygon: <br>In Qgis which is a very userfriendly OS GIS you have 'Cut polygon', do try and find the difference.<br><br>Polygonising from lines:<br>Open JUMP has one of the most userfriendly approaches.<br>Create lines and polygonise in OpenJUMP and the software automatically <br>creates a folder for Dangles (un-wanted line pieces)<br><br>The query is more for Vector GIS, I suppose.<br><br>GRASS GIS:<br>It has so many features for Image analysis and Raster GIS, the commercial GIS need a barge pole to even touch it. The vector Part of GRASS is robust too.<br><br>Ravi Kumar<br><br><br><b><i>Markus Neteler <neteler@osgeo.org></i></b> wrote:<blockquote class="replbq" style="border-left: 2px solid rgb(16, 16, 255); margin-left:
