Google Maps Plugin return coordinates
Was out of town so couldn't answer this question until now. With Google Maps for Craft you can do so like this:

{% set marker = entry.yourMapField.getMarker(0) %}

{{ marker.lat }} {{ marker.lng }}


Or you can loop through all the markers on the map like this:

{% for entry in craft.entries.section('news') %}

    {% for marker in entry.yourMapField.getMarkers() %}

        {{ marker.address }}&lt;br&gt;

    {% endfor %}

{% endfor %}
