I would like to know how to accomplish the following task using QGIS.
I have an existing point shapefile representing sanitary sewer manholes and an existing polyline shapefile representing sanitary sewer pipes. All pipes are connected (snapped) to a manhole and all manholes are approximate location. Recently a survey crew collected GPS points (4,000) for some of the manholes. I need to move all manholes and pipes to their correct location. How can this easily be done using QGIS?
