This plugin replaces coordinates, i.e. latitudes and longitues, between a [coord]-Tag with a link to Google’s map service.
Example:
[coord]49.579276566362985,10.9292078018188488[/coord] comes up as <a href="http://maps.google.de/maps?ll=49.579276566362985,10.929207801818848&q=49.579276566362985,10.9292078018188488&t=kbd&z=15" title="Google Maps" rel="nofollow ugc">(49.5792, 10.9292)</a> 
To adjust the link layout of transformed links open wpCoordinates.php in your favorite editor and adjust the following variables:
<ul>
<li><code>$zoom</code>: the zoom level, default is 15. Try some values between 1 and 17 (I guess)</li>
<li><code>$type</code>: map type, i.e. m for map, k for a satellite image, h for hybride (satellite image with street names, etc.), p for terrain</li>
<li><code>$url</code>: URL scheme, replace .de with .com for an english version of Google Maps. DON’T forget %LAT% and %LONG%</li>
</ul>

The plugin aims to provide a quick and easy way to store googlemaps on your blog. By storing maps, requests to google map api are kept minimum 
and the possibility of not having a map show up on your page if google service is interrupted is reduced. Shortcodes are provided in the editor to make including a map you have created 
even easier.
Planned extensions will include editable notes for map flags and ajax to make creating a map more intuitive and support for the javascript and google 
earth apis.
