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.
The standard style for OpenStreetMap, like most Web maps, uses the Web Mercator projection. Web Mercator, Google Web Mercator, Spherical Mercator, WGS 84 Web Mercator [1] or WGS 84/Pseudo-Mercator is a variant of the Mercator map projection and is the de facto standard for Web mapping applications. It rose to prominence when Google Maps adopted ...
} is used to generate the Open Street Map zoom level for an object.. The template accepts a number of (optional) parameters that describe the physical dimensions of an object: The template accepts a number of (optional) parameters that describe the physical dimensions of an object:
Maps, and others) use a variant of the Mercator projection for their map images [23] called Web Mercator or Google Web Mercator. Despite its obvious scale variation at the world level (small scales), the projection is well-suited as an interactive world map that can be zoomed seamlessly to local (large-scale) maps, where there is relatively ...

Some online applications that allow the user to zoom into an area often include locator maps to assist in navigating the main map or image. For example, Google Maps uses a locator map to orient visitors to its site, included as a toggle button. These locators often feature a movable box that assists the user with navigating the main map.

DTED (or Digital Terrain Elevation Data) is a standard of digital datasets which consists of a matrix of terrain elevation values, i.e., a Digital Elevation Model.This standard was originally developed in the 1970s to support aircraft radar simulation and prediction.
