i'm using Qchainage on a Polygon to Line layer, and in the input dialogue there's degrees instead of meters .. and i've used trial and error to find a suitable distance ... but the issue is that not all the created points are at the same distance from each other

my process goes as follows Creating a buffer >> polygon to line >> QChainage

is there a way to input meters ?

  • did you check if you coodinate system is in meters?

  • and how to change the coordinates system for a layer?

Save your data in a CRS that has meters as its unit of distance. When you do, QChainage will also work in meters (it works in the units of the layer)

  • i cant add or import new data since i work on a server

  • Please be more specific on your limitations, because if you can create a QChainage layer, you surely also can create a layer where your data is saved in appropriate CRS. Commented May 15, 2017 at 7:14
  • so just to be clear .. i should save the layer im working on as CRS >> create the buffer >> create the polygon to line layer>> create the Qchainage should be in meters?

    Yes, that is correct. It is all down to the choice of CRS. Commented May 15, 2017 at 7:21
