[Qgis-user] QGIS - Cluster Points alongside lines by a limit

[Thayer Young]

Hi Fabian,
Assuming 2 things, first that you lines have a unique ID field, and second that you are not concerned with network connectivity:   You can use the "Join Attributes by Nearest" tool. Set your points to input layer1 and your lines to layer 2. For the "Layer 2 fields to copy" choose the unique ID for the lines. Set the "Maximum nearest neighbors" to 10. 
You would then categorize the symbology by the line unique id.

Hello together,

in QGIS I have a street layer (lines) and a house layer (points) with a start point.
(picture 1)

I want to cluster the points alongside the line layer in groups of 20 or 10 points. The result should look like that:
(picture 2)

Each coloured line in picture 2 represents a different cluster. The result was made manually and took a long time, is there any possibility to cluster the points automatically?

I prefer groups of 20 and 10 points per line, in some cases I have to use a bit less or more.


You can find the picutures and the layer examples here:

Thanks in advance!

Best regards,
Fabian Laumer
