Hi all<br><br>I've used Grass to build a topology out of a polygon shapefile, so far so good. <br>I now need to export it as an arc-node topology (i.e. boundaries with startnode_id, endnode_id) which I will then use in PostGIS.<br>
<br>Does anyone know of a way to get the nodes from the topology and attach these attributes to the boundaries?<br>I know I can get the start/end coordinates, but I need the unique nodes and their ids.<br><br>Thanks<br><br>
