How do I rectify a distorted aerial image in QGIS?

Question

When I place an aerial image in QGIS 3.4.15 it becomes distorted (in the attached the left image is correct, the right image is distorted). How to I rectify this?

Answer 1

The image is being reprojected on-the-fly to the map Coordinate Reference System (CRS), which is not the same as the image CRS.

You can change the map CRS with the Project ~> Properties ~> CRS setting.

If you tick on No projection, all data will be displayed without being reprojected.

Or you can get the raster layer CRS by selecting it and checking the Layer ~> Layer Properties ~> Information ~> CRS data. Then you can set the same CRS to the map (project).
