feature: which geographic objects should be displayed (corresponds in the map data to the name of the field under the objects field). The default is value countries. ids of geographic entities: The actual parameter names depend on the base map and the selected feature. For example, for the above mentioned world map the ids are ISO country codes.
An approximation of the AuthaGraph projection. AuthaGraph is an approximately equal-area world map projection invented by Japanese architect Hajime Narukawa [1] in 1999. [2] The map is made by equally dividing a spherical surface into 96 triangles, transferring it to a tetrahedron while maintaining area proportions, and unfolding it in the form of a rectangle: it is a polyhedral map projection.
The aim of WikiProject Maps is to improve the quality of maps across the Wikimedia Foundation. The Maps for Wikipedia page is an overview of different formats and tools for maps available on Wikipedia. The Map conventions page provides advice for creating and improving maps. The Map workshop page can be used to add your map requests and your ...
For example, for the above mentioned world map the ids are ISO country codes. The values can be either colors or numbers in case the geographic entities should be associated with numeric data: DE=lightblue marks Germany in light blue color, and DE=80.6 assigns Germany the value 80.6 (population in millions).
However, if the map is marked with an accurate and finely spaced latitude scale from which the latitude may be read directly—as is the case for the Mercator 1569 world map (sheets 3, 9, 15) and all subsequent nautical charts—the meridian distance between two latitudes φ 1 and φ 2 is simply
With the circumference of the Earth being approximately 40,000 km (24,855 mi), the maximum distance that can be displayed on an azimuthal equidistant projection map is half the circumference, or about 20,000 km (12,427 mi). For distances less than 10,000 km (6,214 mi) distortions are minimal.

As an atlas software, the 3D World Atlas has many features. These include, but are not limited to, world maps on a 3D globe, thousands of tables and charts, national flags, and a world clock. [2] The software also includes distance measuring and in-depth information on every country, including independence days, government types, and such. [2]
