I have imported the Google satellite imagery though open layers plugin. I would like to clip it to a polygon shapefile of New York State. Is it possible to do this? I tired the GDAL Tools and it wont let me select the imagery layer.

If you are looking for aerials of New York state, check the NY GIS clearinghouse: gis.ny.gov/gateway/mg. –  Dan C Mar 12 '13 at 19:29

Googles terms of uses forbid saving, reprocessing or creation of derivative work of google maps data and this is why there is no option to save the Google layer in QGis.

If you don't care about that ( private noncommercial project, studying, no redistribution, ...), then there are two options:

  • You simply create a new polygon layer in QGis, make it editable and digitize your buildings or area of New York State.
  • You can get a georeferenced raster using Project | Save as Image ...

However, i would advise you to look for other free available sources or purchase your own satellite images!

Point well taken, I have another source, but in some areas the resolution isn't very good. I almost ask what is the point of being able to import that information if you cant use it. –  LandArch Mar 12 '13 at 19:09
    
@LandArch that is the exact reason why most GIS professional stay away from google maps. –  Devdatta Tengshe Mar 13 '13 at 1:44
    
I assume that the Bing and Yahoo satellite imagery contains a similar clause. I heard of some issue with using the Google imagery, but I did not get the details. I appreciate the information. –  LandArch Mar 13 '13 at 12:26

Alternatively you could find Imagery here http://gis.ny.gov/gateway/mg/

thanks that is the other resource that I typically utilize. Unfortunately the more rural areas areas have a resolution that make its difficult to zoom in on a small site, i.e a residential lot. –  LandArch Mar 13 '13 at 12:25

Import a raster from google earth. georeference it and then you may extract the raster with a polygon layer.
