Users can explore the globe by entering ...
At the outer most zoom level, 0, the entire world can be rendered in a single map tile. Each zoom level doubles in both dimensions, so a single tile is replaced by 4 tiles when zooming in. This means that about 22 zoom levels are sufficient for most practical purposes. The Web Mercator projection is used, with latitude limits of around 85 degrees.
World map. A world map is a map of most or all of the surface of Earth. World maps, because of their scale, must deal with the problem of projection. Maps rendered in two dimensions by necessity distort the display of the three-dimensional surface of the Earth. While this is true of any map, these distortions reach extremes in a world map.
These all perform basic tasks helping the viewer in understanding the world.
