I'm trying to find a plugin of some sorts to help me create a point along a line at a certain distance. This does not require a import from a CSV file, just a field where I can insert a certain distance in meters. And where I can select the line where it should measure from and select from which side of the line I want to start measuring.

I'm searching for quite a while now and I'm only finding a lot of plugins which nearly do the same but most of these plugins require CSV import, or Chainage, which I don't need nor want.

I'm working with specialized electric fault meters which gives me distances along a cable where there should be a problem of some sorts, and it would be awesome if I could simply input the distance and get an exact location along the cable I've drawn.

PS: I'm not very skilled with coding, I can do some basics but that's about it.

  • Have you had a look at the `points along lines``tool? If so, how does it not suit your needs?

  • What you want is probably linear referencing (also called dynamic segmentation), have a look at the LRS plugin

  • well @Erik the problem is that when i have a cable which is, say 2,5km and i have a disturbance at say 120m, is get a lot of points which are quite unnesecary.

The "Points along geometry" algorithm will add the point for you, but there is no option to only add one point:

This algorithm creates a points layer, with points distributed along the lines of an input vector layer. The distance between points (measured along the line) is defined as a parameter. Start and end offset distances can be defined, so the first and last point will not fall exactly on the line's first and last nodes. These start and end offsets are defined as distances, measured along the line from the first and last nodes of the lines.

I guess that if you use the Start offset to specify your distance and then choose a sufficiently large value (larger than the maximum line length) for the Distance between the points you should achieve what you want.
