I'm a new learner when it comes to QGIS.
I have a JPEG image and I want to convert it into a shapefile. The problem is when I polygonized it, the resulting image is inverted. So I decided to just digitize it manually. Now since the image I used has no coordinate reference, I assigned WGS 84. By the way I'm having difficulty assigning any geographic coordinates, so I just input WGS 84. Then I open an OpenLayers plugin which is the Bing Maps. It was just then that I realized that only raster layers can be georeferenced. So I open again my JPEG file and started georeferencing it.
When it was done the result is way off the grid. what do I have to do?
I am using QGIS 2.4 version.
