Due to an incorrect datum coordinates, I need to move a large number of elements in shapefiles by a specific distance. In 2.8 I would have used the Affine Transformation tool, but this does not appear to be available to QGIS 3.6.

Is there another tool or process I can use?

There's also the GRASS tool v.transform (in the processing toolbox), which

Performs an affine transformation on a vector layer.

Make sure you're running the QGIS version that says "with GRASS" in the name, otherwise you'll get an error message when trying to run a GRASS tool.

Note: I found this tool by searching the processing toolbox for the term "affine." The processing toolbox searchbar is a great place to go when you have a question along the lines of

  • "Is there a tool that does this thing?" or
  • "Where's the tool that used to be called this name?" or
  • "Where's the this name tool that used to be in the that name menu?"

  • Thanks, this worked fine. – Peter Cornelissen Aug 9 '19 at 17:20
  • I tried using GRASS processing tools such as this one through QGIS on Mac for a while now but still unsuccessfully... A number of questions are open on this issue. In QGIS I can translate (move x,y) and rotate with the relevant tools, but I'm stuck at scaling the data: is there a native tool to scale a vector layer? – benny the spaceman Feb 12 at 2:03
  • According to the original asker (Peter Cornelissen), both of the answers to this question worked for him. But if neither solution works for you, by all means post a new question. – csk Feb 12 at 3:32

You could use the Translate tool from the Processing Toolbox:

This algorithm moves the geometries within a layer, by offsetting them with a specified x and y displacement.

    This worked fine too, but didn't need GRASS. – Peter Cornelissen Aug 9 '19 at 17:20
  • @PeterCornelissen - Most welcome, glad it helped :) – Joseph Aug 12 '19 at 13:11
