I'm trying to georeference a JPG file, and I have attempted several tries using between 3 and 20 ref points, but it keeps being off. I have georeferened files without problems before, but never had such problems. Is there an alternative to georeference a picture? The ref. points all points in different directions, and kind of look like, they try show a low pressure map (:

The green line is a QGIS layer, while the dark grey are the picture. I have tried to see if there a the same distance in some points, so that I maybe could just add or subtract to the point, but is was not the same difference everythere, not even close.

    What exactly is "off"? Which software are you working with? What settings did you use? Can you provide the image and the ground points? Commented Jan 27 at 13:25
  • As in, it does not add up with the background map. I'm using QGIS. I put a picture in the comment it seems. But as I put my reference points in, they do stretch out, to show how much they differs from the qgis map, but they strech in different directions. hornestly they kind of look like they trying to show a low pressure (: Commented Jan 27 at 13:33

    Please Edit the Question in response to requests for clarification. It's not fair to those who would help to make them review all the comments to understand the problem. Commented Jan 27 at 13:41

    Please provide all the details, settings you made etc. Otherwise, we can only start guessing. Commented Jan 27 at 14:10
  • You don't indicate what coordinate systems are involved. You should georeference your image in the same coordinate system your image was created in not in the base map's if they differ. If necessary project your background map to the images' CRS and then attempt a georeferencing. It might help if you show how well dispersed around the image your control points are, and how "good" they are, and indicate what transformation methods you tried with those control points.
