Nantucket Ma Map: Switch between Map (street map), Satellite, and Hybrid map modes by using the buttons on the upper right of the map. Move the map by clicking and dragging the map or by using the directional buttons on the left hand side of the map. Zoom the map by clicking and dragging the slider or clicking "+" and "-" on the left side of the map.
You can also geocode or get lat/long coordinates for a known location that does not have a street address via a street map or satellite images. In satellite view you can get the gps coordinates for a specific parking space in a parking lot -- it's that good.
