Hi,
Actually, users-oriented-crowdfundings have proven quite successful in the
past. And it works something like this:
- A small number of non-developers members of the community (aka users)
discuss and gather ideas of how to improve or implement a certain feature;
- They contact one or more

Hi Calvin and list,
Have you looked at the GRASS GIS v.generalize tool?
https://grass.osgeo.org/grass64/manuals/v.generalize.html
The Douglas-Peucker algorithm is implemented there and I have used that
with (topologic)success recently on many touching polygons. Should work
for polylines
As I'm a new user of this list, hi to everyone !
As we had this problem, here's a working trick well known but a bit hard to
find : https://issues.qgis.org/issues/20077#note-2

I am guessing this is working on Cartesian coordinates and not geodesic
which is fine if you have a local projection. I think I will go ahead and
implement some similar geodesic algorithms. Thank you for the GRASS link.
It will help.
Thanks,

I suspect the lines aren't **exactly**

- multiparts to single parts
- snap geometries to layer, to snap the end points exactly

- retry merge
I tried this, no
Ciao, credo che l'immagine non sia piú quella corretta.
