OSM Categories embed an OpenStreetMap map to your page by using the OpenLayer API. For every category in your blog a differnt layer on your map show markers for every article with an geotag. 
You just have to save the lon and lan parameters in a custom field. It’s possible to use different marker images for every category.
In your page just insert the shortcode: [osm-cats]
Open the plugin settings page for basic settings like:
<ul>
<li>map dimensions</li>
<li>map center point</li>
<li>initial zoom faktor</li>
<li>exclude categories</li>
<li>article custom field for marker lon and lat parameters</li>
<li>marker popup content</li>
<li>marker images path</li>
</ul>
It’s still BETA so please send me feedback and your ideas! Thanx a lot.
