Hallo Michael:

I assume you are referring to the parameters in the lower part of the georeferencing window? I qset up a test georeferencing and the screen shot is below.

In this case, the values are the transformation parameters based on the 4 GCP's I used.  The value after the | are the coordinates of the cursor measured from the top left corner.

Is this what you are referring too?

If the values are in your main map view, something has gone wrong in your georefrencing and perhaps you do not have enough GCP or one of your coorinates is wrong.  Try overlaying some additional vector or raster data to confirm your image is in the right spot.

Hello,


I use the Georeferencer in the QGis Raster dialog för a long time. But yet I need further and detailed information about the quality parameters of the  transformation.

For example I did a Helmert Transformation and find in the lower part of my desktop the parameters. There are two scaling factors for each coordinate axis, but they  are as the following value (0,05325...) ...I expected something in relation to the original scale of the scanned raster map (f.e. 1 : 1250 -> 0,0008).

It will be very helpful, if there is a explanation to it ! Thanx a lot !




Mit freundlichen Grüßen
