Add-on:Wikipedia

The Wikipedia layer consists of hotspots with click-through links to relevant Wikipedia articles.

The current version is a snapshot from March 4, 2005, with 572 points.

Demo images:
 * Antartica
 * San Francisco
 * Washington DC

Links to geographical coordinates is a new thing in Wikipedia, so the availability of points is as of yet pretty sparse in most areas.

Installers are available:
 * V1.2e: ftp://ftp.kvaleberg.com/pub/Worldwind_1.2e_Wikipedia_0.1.exe
 * V1.3: ftp://ftp.kvaleberg.com/Worldwind_1.3_Wikipedia_0.2.exe

For a guide on how to add coordinates to other Wikipedia articles, see the style guide for geographical coordinates.

Developments
This is really a proof-of-concept at the time being.

Some things to consider:


 * The hotspots really need to be categorized. Especially true the more points there are.


 * The map scale from Wikipedia probably should be reflected in visibility-from-altitude.


 * The number of points from Wikipedia will soon reach several thousands. Perhaps the XML format is not suitable?


 * Various things in the XML has just been inherited from other layes, and probably needs to be looked at.


 * Is it possible to have a text appear in addition to the icon for the hotspot?


 * I'm sure there are efficiency issues.
