Google layers extension is very good at this. 1/ open qgis 2/ get the google layers plugin 3/ choose projection = google mercator (EPSG: 900913) 4/ get some data where your area is located (couple of roads, rivers, whatever... just so that you know where you are) 5/ menu Extension / Google layers / Settings 6/ dialog box: choose "satellite" option 7/ go where you wish 8/ menu Extension / Google layers / Google layers 9/ miracle: satellite image from google maps is right there If you zoom close enough, you'll get a decent image, georeferenced, etc. The images end up somewhere in a temporary directory. On my GNU/Linux Debian machine, they arrive in /tmp/google_layers/ with some fancy names. What I do is, after I downloaded the images I want, is merge them into a unique file. For instance, this is the command I used last time I did this task: pie...@duran:/tmp/google_layers$ gdal_merge.py -o google-satellite-cote_ivoire_sl.tiff google-satellite-z8-11-24092010_2203221285358602.jpg google-satellite-z8-10-24092010_2203221285358602.jpg google-satellite-z8-7-24092010_2203221285358602.jpg google-satellite-z8-8-24092010_2203221285358602.jpg google-satellite-z8-9-24092010_2203221285358602.jpg google-satellite-z8-12-24092010_2203221285358602.jpg google-satellite-z8-13-24092010_2203221285358602.jpg google-satellite-z8-1-24092010_2203221285358602.jpg google-satellite-z8-2-24092010_2203221285358602.jpg google-satellite-z8-3-24092010_2203221285358602.jpg google-satellite-z8-14-24092010_2203221285358602.jpg google-satellite-z8-15-24092010_2203221285358602.jpg google-satellite-z8-4-24092010_2203221285358602.jpg google-satellite-z8-5-24092010_2203221285358602.jpg google-satellite-z8-6-24092010_2203221285358602.jpg As you can guess, this was in Ivory Coast. Before, I used to use viking to download images, then export them, and georeference the final image. But with this extension, it is more convenient, I find. Hope it helps.
