I'm doing some polygon (boundary) cleanup, and am wondering if it is possible to add a node/vertex to a set of selected polygons or even a single polygon.
By the way, the QGIS topology editing tools are incredible - extremely simple but very accurate and take so much of the work away from doing such manual work.
QGIS gives the ability to remove selected nodes - amazing that the topology is preserved and even improved when cleaning up excess nodes. Great stuff!
