I am trying to follow the tutorial in http://www.qgistutorials.com/en/docs/georeferencing_basics.html to do the image georeferencing. But every time I got strange results.
My image is self created picture, with several known points (I obtain the coordinate of these points from handheld GPS receiver). I'd like to match the image to real world coordinate.
When I open the CSR property of the geotiff file, the coordinate reference system shows Selected CRS, USER100000 (as I'm expecting EPSG3857).
Could anybody help with this?
