Re: [Qgis-user] summing linelengths

[Reginald Carlier]

Hi Richard,

Unfortunately in QGIS 2.14 there is no help dialog with the tool so I did not 
get the explanation you posted. 
I tested the tool and it does work indeed. It makes the sum of the line 
features for each input record of the polygon layer.
I agree with you that the name should be changed, and  I am glad there will be 
explanation available in future QGIS versions.

Hi Reginald,

Running QGIS in english, you get the following descriptions in the dialog (at 
least with me here on QGIS master, in 2.14 there is no 'help'
text I see...):

Sum line lengths

This algorithm takes a polygon layer and a lines layer and measure the total 
length of lines and the total numer of them that cross each polygon.
The resulting layer has the same features as the input polygon layer, but with 
two additional attributes containing the length and lines count of layers 
across each polygon. The names of these two fields can be configured in the 
algorithm parameters.

Did you check that too?
I'm not sure what exactly the purpose or use-case is for this. But instead of 
removing maybe someone can provide a better name?

Regards,

Richard Duivenvoorde

​I've used that tool in the past, for example to compute street network
length per district. It works fine and should not be removed​
​
​. Like all tools, CRS of both input layers have to match. A better (but
longer) name would be "Sum line lengths per area".

Best wishes,
Anita

[Reginald Carlier]

Hi,

I'm using QGIS 2.14 and found that the 'Vector tool' > Analyse-gereedschap > 
Basisstatistieken was what I needed.
I still don't know what the tool 'Lijnlengtes sommeren' does. This tool should 
be removed as it does not generate any output.
