So in the QGIS class probably the one thing I’ve said more than anything has been “If they ever get a trace tool I’m done with the other stuff”. I think I was somewhat confident no one would ever make a tool. There is a trace tool plugin but I always would sit and use it and go (mouse click) and hold the (shift) and click…and dangit I need to mash (CTRL) possibly and I would end up more confused than happy. It had great documentation though – I just could never get used to using it.
Anyway I was going through the changelog*(not complete) for 2.14 and found – GASP – a Trace tool. Lutra Consulting*(Contributors and Supporters to the QGIS Project) rebuilt the tool I just poked at*in the first paragraph and now it’s about perfect.
So when you open up QGIS 2.14 you will see a magnet:
So what does this mean. Set your snapping options under options (on the main menu) and pick a good snapping distance for your data. For this I want my line to snap if it’s within 20 feet of the polygon boundary. *Edit your*layer. Click on the Trace (magnet) and click Add Feature. In this case a road needs to follow the polygon boundary. I click where the line starts. I click where the line ends.
Before I create a road
Road Created with two clicks and the Trace ToolAnd Polygons – Same idea. Set your snapping……click 3 times….
