Hi Adam You could load the data into PostGIS and use pgRouting to build a network topology and then use the built-in pgRouting functions to analyse the graph for dead ends. Then invert your selection. See http://docs.pgrouting.org/2.0/en/src/common/doc/functions/analyze_graph.html for more info. HTH Ross
