[Qgis-user] Hachure construction

[Frank Broniewski]

Hi,

I'd like to construct manually some hachures in order to show the
terrain form, like in ye olde maps
(http://en.wikipedia.org/wiki/Hachure_map)

I am working with contours that I have available. Using the snapping
options I can already draw lines between two contour lines just fine,
but a hachure line is usually drawn in the direction of the steepest
slope. So it would be useful to have a length indicator, just like with
the measurement tool, when digitizing lines. Because the shortest
distance between two points would represent the steepest slope and that
is what I want to know.

So how can I get the current line length while digitizing? Is there some
plugin? I am also not afraid of using Python to achieve this, but I've
never done any QGIS modding so far ...

Many thanks,

Frank
