I am the developer of FlowMapper plugin. Hope you find it useful. Regarding your question: FlowMapper offers two types of flow length caculations: (i) for cartesian coordinates (e.g. UTM x y) (ii) for geographic coordinates (e.g. WGS84 easting northing) User must properly choose either CARTESIAN or GEOGRAPHIC calculation depending on the type of ...

I get the solution of the problem directly from the developer of the plugin, I'll post here the answer I get: FlowMapper offers two options for distance caculation: (i) cartesian coordinates (e.g. UTM x y) (ii) geographic coordinates (e.g. WGS84 easting northing) As far as I can see, you are using geographic coordinates (x-y). Please check ...

PointConnector is now updated to support integers as input, which should solve this issue. Please let me know if it doesn't!

I took the same style values as you, and it looks quite good: but it looks better with a svg symbol. With the standard > I get this: The saved style looks as follows: <renderer-v2 symbollevels="0" type="singleSymbol"> <symbols> <symbol alpha="1" type="line" name="0"> <layer pass="0" class="SimpleLine" ...

Well, this is not the perfect solution, but I created SVG marker with the required symbology. Then I set the needed interval and finally it works how I want!

The v.split.length function from GRASS should do exactly what you want by splitting the line into equal segments defined by the user without the need for a point layer. Here's a simple example of a straight line (it also works on non-straight and multiple lines): I added a column to calculate its length using $length in the expression: Using the ...

If a (somewhat manual) approach is fine for you, you could route from the start to the end point e.g. using the Road Graph plugin. Otherwise, you'd have to find a way to automatically detect where the start and end points are.

Do you mean connecting the endpoint of a line to the startpoint? This should help http://postgis.net/docs/ST_AddPoint.html.
