I am a beginner using QGIS (1.8.0 Lisboa) on a Mac (OS X 10.6.8 Snow Leopard). I work on a file with two layers in the following sequence (top to bottom):

  • a vector polygon layer with a few outlines of various buildings in france and italy (CRS: EPSG:4326 - WGS 84 - "on the fly" re projection is activated )
  • a google satellite layer uploaded via open layer plugin.

Sometimes when changing the scale (scrolling in and out) the google layer updates a little wrong in size or position compared to the polygon layer. But as soon as I "pan" the map everything reconstructs right. Now the problem I have concerns the print composer.

The result of any kind of export - pdf, or image or svg - of my map (vektor layer + google layer in the background) differs from what is shown in the preview of the print composer: the vector layer and the google layer positions are mismatching and in a different scale. I can send some pictures showing screenshots of the print composer preview and the final results if required.

I tried almost everything: - new files with different CRS settings - "cache" update preview - "render" update preview - different paper sizes, - different scales,

The problem appears only using an open layer map (google, openstreetmap...). If I try the same using two vector layer (shapefile) - one with the buildings, another one with the city in background - everything works out great.

...exasperating! Since it is a real important research project I would be very grateful for some help and tips.

Thank you all in advance for the support

do you manage to solve this issue? I'm in the same condition, trying to overlay my data over bing aerial. I even tried 1.9.0 nightly build. I filed a bug here, no response in two weeks. Good luck! – sanzoghenzo May 9 at 20:56
