Hi All! I am new to the GIS topic and also new to QGIS. My problems seemed to be very easy, but with my last try I was then running completely wrong and I hope you can help me since I thought I have done everything correctly.
I have added 2 pictures as example (KEWR_AFC.png, KEWR_AGC.png)(originally its a .tiff, but does not matter for this test). On the KEWR_AGC I have drawn the grid lines to make it easier to set some coordinates. Be aware that I made an error on the right side and one gridline is wrong. But for this example and the test it should not matter if its known. Also there is a Reference point in the middle of the chart as confirmation that everything is ok after georeferencing. On the KEWR_AFC there are a lot of Points already defined with coordinates which can be used to georeference the .png. I have now tried everything but the result was tilted and shifted in such a way, that it was unreadable or completely unusable because the coordinates have been wrong. Is it because of the variation? Or wrong KGS? I had - depending on the choses options - red lines indicating the tilt/shift with extremely movements... So can anybody help me how I have to georeference (especially the AGC), that it is correct? <http://osgeo-org.1560.x6.nabble.com/file/n5166955/KEWR_AGC.png> <http://osgeo-org.1560.x6.nabble.com/file/n5166955/KEWR_AFC.png> Thanks a lot already for help in advance!
