Hi Paolo, I included the code in a small plugin for you to check it out. It's on github: https://github.com/bstroebl/Station Could certainly be improved by snapping to the line (snap to segment must be turned on). regards Bernhard Am 08.09.2016 um 08:39 schrieb Paolo Cavallini: Hi

Re: [Qgis-user] Linear referencing in QGIS

Hi Bernhard I do not quite understand what you mean with the m or z picker tool, however I have some Python code here in operation that returns a "station" on a line by clicking on the line (or near it, as you won't hit the line without snapping to segment). A "station" is a position on the

Hi Andreas, I think a geometry generator symbol should be able to do this. 1) On the point layer join the line layer 2) Generate points from line information plus offset Matthias On 09/07/2016 04:51 PM, Neumann, Andreas wrote: > Hi, > > Yes, I know about LR expressions in the current master

Re: [Qgis-user] Linear referencing in QGIS

Hi All, I've been using linear referencing extensively here to produce european reference datasets of water bodies. Postgis works just fine and fast. What I have been missing, and average users probably miss that too, is: - A tool to "calibrate" a route from data, points, or lines: Currently LRS

Re: [Qgis-user] Linear referencing in QGIS

Hi, Yes, I know about LR expressions in the current master versions. So one could visualize the events table through a virtual geometry column - would that work? I will forward all this information to my friend. Greetings, Andreas On 2016-09-07 15:34, Matthias Kuhn wrote: > Hi

Hi Andreas, In QGIS 2.18 / QGIS 3.0 this should be possible via expressions: https://github.com/qgis/QGIS/commit/e110ba7d54b0ac7d3f63e8ed7eaebb2845f9f38c Best regards Matthias On 09/07/2016 02:24 PM, Neumann, Andreas wrote: > Hi, > > A friend of mine asked me if QGIS can do linear referencing

Re: [Qgis-user] Linear referencing in QGIS

Hi Paolo, Thanks - it looks quite powerful. And yes - they would use it with Postgis data. Can one also create point or linear events interactively in QGIS? I did not see this in the description of the plugin. I see that one can query measurements in the "Localize tab" and that an events table

[Qgis-user] Linear referencing in QGIS

Hi, A friend of mine asked me if QGIS can do linear referencing - e.g. symbolizing road data speed limits along a road, lets say from km 0 to 0.76 there is a limit of 50 km/h, from 0.76 to 1.23 there is 80 km/h limit, etc. The idea is to symbolize these road segments without having to actually
