Don't know if you have already discovered this for yourselves but Quikmaps provide an easy way to link into Google maps (or even Google Earth!) from a Moodle course. Simple HTML is generated by the site and this can then be added to an HTML block.
Enjoy

Thanks for that link David. Just had a look and a 'play' and I think some of our schools, both primary and secondary would be quite interested.
