Wikipedia:WikiProject Maps/Conventions/Orthographic maps
This page provides conventions for the creation of orthographic maps. Orthographic maps display a country (or set of countries) on a globe representation of the world. Like location maps, orthographic maps are very basic, and should have very few, if any, labels. Maps should be centred on the subject of interest.
Usage: These maps are often used in country infoboxes Template:Infobox Country to demonstrate where a country is in the world.
Where: These maps can be found on Wikimedia Commons, Grey-green orthographic projections maps.

Further needs: Dimensions: 550x550 pixels. Border of the globe: 1.5 pixels. Latitude/longitude grid: .3 pixels in black with 77 in the transparency value. Coasts and borders of countries: .3 pixels. Legend: not needed. Scale: not needed (since misleading). Scale is non-linear across the globe Projections: Orthographic projection Gradient: :File:Orthographic gradient.svg |
Motivations
To identify where a country is with respect to other nearby countries that the viewer may know about.
History and current work
The first of these maps was uploaded to Wikimedia Commons by User:Ssolbergj in 2008.
These conventions are from Commons:Grey-green orthographic projections maps, although maps are not [yet] consistent in presentation style. Discuss proposed improvements.
- The surrounding area colours were taken from Commons:Template:EU-SVG-en.
- The gradient, border of the globe, and the colours of the latitude/longitude grid were based on original files created by User:Ssolbergj.
- Perlshaper tutorial (French)
Examples
Two different orthographic color schemes have widespread usages within Wikipedias and Wikimedia websites.
