A concrete subclass of ImageSource that acquires images from Google maps.

Methods::

grab	Grab a frame from Google maps

char	Convert the object parameters to human readable string

Examples::

Earthdemo1.m

Notes::

You will need to set your own API key which you obtain from Google: developers.google.com/maps/documentation/staticmaps/#api_key You may set the key by using setenv('GOOGLE_KEY','long_GOOGLE_key_string');
You only need to do this once per session.
Google limits the number of map queries to 1000 unique (different) image requests per viewer per day. A 403 error is returned if the daily quota is exceeded.
Maximum size is 640x640 for free access, business users can get more.
There are lots of conditions on what you can do with the images, particularly with respect to publication. See the Google web site for details.
