I was given a bitmap file representing the new boundaries of regions we are supposed to be working on for a project. I couldn't get this in a spatial format no matter how hard I tried. I did have some similar boundaries but there were a few changes here and there. I loaded the bitmap into the Qgis georeferencer and using my old boundary shapefile matched some points up and created a world file. I could then load the bitmap into Qgis. Here it is:
There's no way I want to redigitize the boundaries when I have something pretty close, and all the overlapping labels on this mean it would be tricky to automatically redigitize the boundaries. Zoom in and see the resolution for yourself.
So I loaded the nearest shapefile and overlaid it, set the fill colour to something transparent (if you set a fill to 'no fill' then you can't see the selection highlight), and activated the magic super labelling from the labelling plugin:
They match up pretty well, but zooming around shows a few problems:
First, select Loga region:
Now I hope there is an easier way of doing this - a way of editing points along common boundaries such that both polygons are modified. But I can't find it, and I've asked on #qgis and nobody seems to know. If not, then this might be the best way to do it!
