    QGIS already has a built-in function for this, it is called "points along geometry'. So no needs additional plug-in for this purpose.

      QGIS's own command "points along geometry' you mentioned is made for a single point.
      It doesn't work for multiple points and lines.
      This great for me.
      I was looking for a long time.
      Thanks again. Noel

      @@ibrahimgedik495 if you know how to do a bit of script you can use the function line_interpolate_point(geometry,distance) to create points using the attribute value in a table, you also need 'geometry by expression' to make it a point layer

      @@StefanoVerugi In the more recent versions of QGIS, there is function called 'Interpolate point on a line' that does the same thing. But these two gives you only one point a time. We cannot get all the points at a time. Runnning batch process is also not an option when we have many points

      @@sharmand5905 yes, in fact I was suggesting to use either geometry generator in layer styling pane or a virtual layer + spatialite

    Hi, thank you for a video. Is it working with decimal numbers? I have tried but could not get results with decimal numbers on my table. cheers

    thank you
    it might be worth mentioning that for the 'Start measure field' in Events to work, the chainage value in the CSV file Points must me a number and not a string
    it took me a little to realize it.. ;-)

      Thank you for your feedback, I'll take care of that from now on.
      Have a great day!

      Chainage field contains length data. This is "shape Length" in Arcmap. It should be double/float.

    What version of QGIS are you using, Sir? I tried to install the QChainage but no luck.

    HOW TO ANNOTATE CHAINAHE AS 0+100, 0+200, 1+1000.... SO ON ON THE ROAD LINE LAYER.

    it is showing the chainage in degrees even i changed it to meters

      Make sure that your are working in UTM or change your file's crs to UTM zones

    Hi all,
    Anyone knows how to do lines along lines?

    • @StefanoVerugi
      @StefanoVerugi ปีที่แล้ว

      you can use the processing tool 'geometry by expression' , starting from existing points on the line, the function is called project(point,distance,azimuth) you need to build your lines
