Re: [Qgis-user] [Fwd: shifted geotif]
Magnus, I'm setting WGS84/UTM19S in Project Properties/Projection, which is the same as stated in Raster Layer Properties/General. (No problem, Angelo is as good or bad as Agustin!)

Hello Angelo, The images are slightly (10 degrees?) rotated in Global Mapper, most probably that you have specified a projection for viewing the images other than they have 'natively'. In Qgis, this is not possible with rasters. They can not be rotated when displaying. If you look carefully, my guess is that the upper left corner of the TIFFs in QGIS is the same as upper left corner in Global Mapper. Summary: Positions is right, rotation is not. (I hope!)

Re: [Qgis-user] [Fwd: shifted geotif]
Agustin and Tim, I received the data Agustin was using. I tried these data against the trunk and have the same problem. Good news is that I tested this on the raster branch and there are no problems, we have Frank W. to thank for that fix. Here is a screen shot, showing good alignment with the background set transparent http://picasaweb.google.com/peter.ersts/QGISScreenshots/photo#5153471299682467538 So, just one more reason for me to burn the midnight oil and make sure the raster branch gets into 0.9.2. -pete Peter Ersts wrote: -- Forwarded message -- From: Agustin Lobo [EMAIL PROTECTED] Date: Jan 8, 2008 12:36 PM Subject: Re: [Qgis-user] [Fwd: shifted geotif] To: Tim Sutton [EMAIL PROTECTED] Cc: Peter Ersts [EMAIL PROTECTED], qgis-user [EMAIL PROTECTED] Done, the jpg images illustrating the problem are in http://picasaweb.google.es/aloboaleu/QgisProblems Agus Tim Sutton escribió: Hi Agustin Please put the screenies on Flickr / Picasaweb or any free image hosting service and post the urls.

Hi Yes now that you mention it, I now remember he (FrankW) committed a fix for displaying non-north up images. So hang on for 0.9.2 Agustin (and cheer Peter on from the sides to get the raster branch merged :-).

!!Aupa Peter!! (but if you cannot make it for the 10th, I think that Tim should wait for the code freezing...) Thank you all for the impressive work.

Re: [Qgis-user] [Fwd: shifted geotif]
No, not at all. Both are the original files. They just get a wrong position when displayed by Qgis, probably Qgis is not interpreting right the geo information included in the geotiff files.
