I've started to use a new Google facility to create an annotated map of our patch (Great & Little Abington). It's all based on the standard Google maps, so you can choose between a street map, a satellite image or both superimposed - see toggle at top right. You can also use a scroll wheel to zoom in and out - and there are lots of other facilities.

I'd be interested to know what people think - will this be useful? I need to mark up all the various habitats and probably add quite a few more points of interest...
