Map 3D

Google Maps

In fact, this Google Earth program is built into Google Maps.
In order to take advantage of this effect, you need to go into the photo mode and the 3D button below the compass will appear.

The terrain is very well implemented: mountains, valleys ...
As for the cities they remained flat, although the whole picture is tilted. The real effect of 3D up to the trees is only in the large cities of the Western world (Europe, Australia, Canada) and much of the US.

To hold the circle, hold down the Ctrl or Shift and use the mouse.

Google Earth

Online version of Google Earth.
Actually it is built into Google maps, and uses one database. So, there is no difference how to use it, separately or through Google Maps.

To hold a circular rotation, hold down the Ctrl or Shift button and use the mouse.

Unlike Google maps, here you can share only the link, and not embed the map on the site. But there's a bone in the menu - a random place on the map.

There is a small globe below which shows the place you are viewing.
