I am trying to georeference my map, But I am unsure how can I rotate my image so that I can find GCP points easily from map canvas.

In this image North is clearly visible.

Using qgis 3.0.

    Just rotate it by 90° in any picture manipulation software. Even paint could work. – Erik Oct 11 at 11:30
  • This does not solve the GCP issue – Roberto Zeeland Oct 11 at 11:38

There are several tutorials on how to geo reference an image. Consider using a search engine with some keywords before asking in the forum. I typed in georeference + qgis in google and found this interesting tutorial.

Good luck!

You can do a quick 90-degree rotate in paint or whatever, as suggested in the comments. Then you can georeference using J Rectifier plug-in. Here's a video on J Rectifier: https://www.youtube.com/watch?v=xLMvIUtdBJ8

  • Problem is after rotating to 90 degrees also when I am opening the image its opening like previous. That's the reason of asking anyway to rotate in georeferencer. Thank you all. – Rashmita Oct 12 at 3:38
  • then it must be an error on saving in paint or whatever you are using to rotate. – AlexS1 Oct 14 at 15:57
