This page is dedicated to give some experience based tips to achieve a better and faster work. The following topics require a good knowledge of ToolMap and its functioning. The strategies proposed can spare you a lot of time, but they require the use of the shortcuts otherwise it risks to actually become longer.

If you want your final results to be consistent you should allways draw your lines at the same scale. In addition, to get fluid results your drawing scale shall be at least 10 time bigger as the original map. By doing so you will see nice and round lines instead of sharp edged segmented ones.

exemple: for a 1:10'000 map digitize your lines at a 1:1'000 scale

When having a enormous project, the number of intersections increase fearsomely. It would be better to have a way to draw them properly without worries. For that purpose the tool Create intersection is really handy.

Start with the drawing of the biggest structures. Vectorize them without interruption. By proceding like that I insure the clearness of those lines.

As you can see on the picture above, there is a lot of intersections I totally ignored. I will now draw the smaller features the same way I would do near the frame.

⇒ Ctrl+i: It automatically create the two intersections I needed.

⇒ Shift + select: It unselect the part I want to keep.

Now my selection is composed only by two superfluous lines which I will delete.

As a result you have here two intersections with very continuous lines on every sides. In addition you can be sure there won't be any snapping issues.
