Note that the lyrs= parameter in the map tile URL and the &v= parameter in the satellite
tile URL change from time to time. If there are
no tiles visible below, I probably haven't updated this recently. Also, the last character
in the sub-domain can usually be any of 0, 1, 2, or 3 (mt1.google.com, khms2.googleapis.com, etc.) They
are all mirrors of each other, this spreads out the traffic so one server is less likely to
be overloaded. For maps, the lyrs parameter currently controls imagery. lyrs=m@??? for regular
maps and lyrs=t@??? for terrain maps.
Your browser may throw dire warnings that this form is insecure due no provision here for HTTPS transport.
It is true that it is insecure,
but it's hardly dire. No information is saved (except when you click the "Save Map View" button), and none of it
is sensitive. Except for the map tiles
requested, the data is not even sent
anywhere, it's all within your browser. You can take my word for it
that it's safe and continue despite the warning. Or you can move on, it doesn't matter to me.
The map above is served from the maps API servers. The sample tiles and related urls below are
from the public maps servers. From time
to time, the imagery on one set of servers will be different than the other set at certain zoom levels.

The sample map tiles are copyrighted by one or more of Google, DigitalGlobe, TerraMetrics, INEGI, TeleAtlas,
NavTeq, and/or others, and are displayed
for educational, non-commercial purposes. It is not permissible to use this tool to
save or download image tiles from this page or Google servers. There used to be no point in doing this
because you used to be able to get any image you needed for personal use by using mapdata URL parameters.
There never seemed to be any documentation of this feature, but the format was simple enough
to get the image you need.
