I'm finding wrong, distorted results with qgis 2.0 georeferencer. We've tried with the same set of gcp's in envi and the same polynomial (deg 2) and there the results are correct, but with qgis the result is very distorted. Actually, the errors represented by the red segments in the georeferencer

I was suspecting something like this too. But the question is that the CRS of the input image should be, by definition, unknown. In case the input image has a CRS, this CRS should be just ignored. Instead, the plugin actually prompts the user about the CRS of the input image. And I do not find any

Hi, Agus; You set your desired CRS in the Georeferencing properties. What I am saying is that this setting seems to be ignored and, in place of the specified CRS, some strange unknown custom CRS is substituted. By going to the layer properties for the georeferenced layer (after it has been

Unfortunately this is not the case with ED50 UTM31N: the resulting layer has the correct CRS, but it is shifted. The points appear where they have to be, but the raster layer is shifted. We'll try with points set on google mercator. Thanks 2011/11/28 den...@dmlinton.net: Hi, Agus; You set

Hi! We are using the Georeferencer tool and the resulting image is shifted, please see the screenshot here: https://sites.google.com/site/filestemp2/home/error_georef.jpg?attredirects=0 We've tried polynomia of order 1 and 2 and Helmert, with very similar results. I think this is a bug, but I'm

I have observed this behaviour in QGIS 1.7.2 and found, upon reviewing the layer properties of the georectified layer, that the coordinate reference system being used was NOT the one specified in the Georeferencing plugin. Rather, the CRS was some unknown custom CRS. Upon resetting the CRS
