Digital Geography

How a QGIS plugin saved my day: autotrace

One of my favourite horror exercises for students was the digitization of geological maps. Everyone hated it as you need to take of snapping options, correct attributes, and always needed to check with the background map which was most of the times a bad quality scan of an old never-heard-of-this-country geological map. Today I needed to do this work for myself… what goes around, comes around.
