Make your mark on Google Maps

Google Maps has now added a ‘My Maps‘ feature, whereby you can create your own annotated maps, with text, photos and video in the ‘bubbles’. It makes the process very easy, but I hesitate to call it a ‘mashup’ – surely that has to require two live data sources (like this)? A few nice extra touches though: the ability to draw polygons (which isn’t easy to do manually); the ability to export in KML format for Google Earth; and (according to O’Reilly) integration with local searching. Possible uses: catchment areas, ward/constituency boundaries… etc etc.
