Please have a look at the post QGIS Linear Referencing. I've described there the functionality offered by the plugin LRS for Linear Referencing on QGIS. LRS improves the usability of the former Linear Referencing plugin by Faunalia. It also does not require the layers to be stored in PostGIS, you can use any QGIS layer (i.e., from any source) for linear ...

You can use the QGIS plugin LRS for that. It accepts points not lying on the line, so you avoid the first step (snapping points to lines). This is the workflow: Based on both a line (routes) and a point (for calibration) layer, go to the Calibration tab. Select the line (pipeline) layer with its route field (a field that identifies routes, it's very ...

I want to expand on the answers above from a beginner's perspective. In this scenario, you have a series of points and you watch to use them as a "blade" to cut a lines into segments. This whole example assumes that you first snapped your points to the line and that the points have the unique ID attribute from their snapped line. I use 'column_id" to ...

You can use the LRS plugin, which enables linear referencing support for QGIS. You can read the documentation here. As you can find there, the plugin supports several linear referencing methods: Route calibration: Helps you to set measures along routes and interpolate between missing values. It is the initial step for performing other operations on routes. ...
