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.

Tutorial: here (perl) or here (French)

Generative tool: Online on ObservableHQ, on the left of the map, click « ⋮ » then « Download SVG »:

Convention

Convention for orthographic maps:

Subject	Colorimetry (RGB/hex)
Subject's area (country, province, state, etc.)	#346733FF R:52 G:103 B:51 A:1
Other areas part of the same political unity	#C6DEBDFF R:198 G:222 B:189 A:1
Claimed uncontrolled areas	#49C946FF R:73 G:201 B:70 A:1
Outside area	#B9B9B9FF R:185 G:185 B:185 A:1
Borders	#FFFFFFFF R:255 G:255 B:255 A:1
Water (ocean, sea, lake, etc.)	#FFFFFFFF R:255 G:255 B:255 A:1
Perimeter of globe	#AAAAAAFF R:170 G:170 B:170 A:1
Latitude/longitude grid	#000000C4 R:0 G:0 B:0 A:0.77
Naming: File:{Location name in English} (orthographic projection).svg File:{ISO 3-letter country code} orthographic.svg
Other specifications: Dimensions: 550x550 pixels Perimeter of globe: 1.5 pixels Latitude/longitude grid: 0.3 pixels Borders: 0.3 pixels Legend: not needed Scale: not needed (since misleading); scale is non-linear across the globe Projection: orthographic globe 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.
