[GIS] Exporting aerial imagery from QGIS

aerial photographygoogleprint-composerqgis

Looked around but couldn't find the answer to my question, so here goes. I am trying to export some decent quality (300dpi) aerial images from QGIS using the OpenLayers plugin. Sometimes it works, and then sometimes it doesn't. The export goes through just fine, but when I go to the file it looks like this.

Weird export problem

Basically I get the image I wanted in the center, but it's hacked off at the sides and corners into a rough oval shape, with a zoomed-in image filling the gaps around it.

It's weird.

This happens whether I export as jpg or pdf, whether I check print as raster or not. I reset the project projection to the google aerial's projection; that didn't help. Previously I thought I was causing this problem by trying to export too large or with the resolution set too high, but now it's happening all the time.

Any ideas why this is happening and how to get around it?

One alternative solution is to use Mobile Atlas Creator (MOBAC)

http://mobac.sourceforge.net/

to download aerial imagery tiles as a .png + worlfile (stipulation remains that it be in EPSG:3857) or depending on where you are the National Aerial Imagery Program has some good aerial imagery that can be downloaded as .Tif files

(or potenitally from your local GIS geospatial gateway) then you can clip it in Qgis and save it as a .tif.
