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.

Subject: [Qgis-user] QGIS - Cluster Points alongside lines by a limit
Message-ID: <6de8cbd3b97447f9b9cd6364e4e84...@hpe-planung.de>

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:

Lines<https://ln5.sync.com/dl/970d2d420/zp8webf5-hghnis7b-dewfmeug-vdx7saav>



Thanks in advance!

Best regards,
Fabian Laumer
