Goals
Should provide a uniform markup for all geographic coordinates
Should provide a user-preferred appearance for all geographic coordinates
Markup should be easy and natural to use
Should be able to have a uniform, extensible way of accessing all types of map resources, avoiding having direct external links to maps in articles
Clicking on a reference navigates directly to a page with external pointers to various resources, with coordinates automatically embedded where possible. The resources can be maps of various kinds, topological charts, satellite photos and others. (((Yike.)))
Create a database of points, enabling generation of navigatable maps with a clickable icon appearing for every location for which there is a Wikipedia article. This has been implemented for NASA World Wind, Google Earth (see below) and Google maps (see below).
Serve as a tool for finding Wikipedia articles describing nearby locations. See also meta:Wikipediatlas.
Adhere to existing Internet standards for geographic coordinates as far as possible
[edit] Examples
All examples use NASA World Wind, with the Wikipedia overlay. This is purely meant as an example of one thing that a coordinated concept for geographical coordinates can be used for.
Links to Wikipedia articles are represented by yellow rings, such as in this view of the Washington DC National Mall, using USGS aerial photos:
