After georeferencing these 3 images onto my basemap (openstreetmap) they do not line up (see how the white lines are mismatching). Why is this the case and how can I solve this problem?
I made sure that when georeferencing I referenced at least 4 points on the basemap. It seems that the images get compressed or expanded, but I do not see why?
I tried alignment tool in QGIS 3.4.2 but this did not work.
I added transparency the georeferenced images so you can see the problem. Along some streets the images lines up perfectly with the underlying Openstreetmap, but then (in the right hand corner the image gets bend direction southeast and the white line does not align with the underlying street. In the transformation settings I also use WGS 84 – pseudo Mercator (the same CRS as used for the whole project).
