In the former case you should look at the snapping options in QGIS - see:</div><div><br class=""></div><div><a href="https://docs.qgis.org/2.2/en/docs/user_manual/working_with_vector/editing_geometry_attributes.html" class="">https://docs.qgis.org/2.2/en/docs/user_manual/working_with_vector/editing_geometry_attributes.html</a></div><div><br class=""></div><div>You can set your roads to snap to edges and vertex and use a specified tolerance in pixels or map units. Then visit each under / over shoot and and drag the road end vertex towards the nearest intersection using the node tool.</div><div><br class=""></div><div>For systematic / automatic fixes, you probably want to look at using GRASS (which you can do via QGIS) and PostGIS to clean your geometries. See for example this thread:</div><div><br class=""></div><div><a href="http://marc.info/?l=grass-user&m=142142976408748&w=2" class="">http://marc.info/?l=grass-user&m=142142976408748&w=2</a></div><div><br class=""></div><div>No doubt others on this list could share their experience on this too. I would caution you to be careful when doing a systematic fix and include a Quality Assurance (QA) step in your processing as you may get undesirable side effects. Needless to say, always work on a copy of your data when doing this kind of work, and archive the before and after state so that you can roll back to before you automatically changed your geometries if needed.</div><div><br class=""></div><div>Hope that helps, hopefully others can chip in with more specific advice.</div><div><br class=""></div><div>Regards</div><div><br class=""></div><div>Tim</div><div><span style="font-size: 12px;
