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.
