Wikipedia Articles + Google Maps = Road Trip?

One of the simplest and most widely used microformats that embeds geolocation information into web pages is appropriately called geo. The specification is inspired by a property with the same name from vCard, which provides a means of specifying a location. There are two possible means of embedding a microformat with geo. The HTML snippet in Example 2-5 illustrates the two techniques for describing Franklin, the best small town in Tennessee.

<!-- The multiple class approach -->
<span style="display: none" class="geo">
    <span class="latitude">36.166</span>
    <span class="longitude">-86.784</span>
</span>

<!-- When used as one class, the separator must be a semicolon -->
<span style="display: none" class="geo">36.166; -86.784</span>
