Compare Maps is a new tool for comparing the maps of four of the major online map providers, Bing, Nokia, OpenStreetMap and Google. The tool in effect creates one map view out of the four different maps.
All four maps are synchronized with each other, so if you drag and zoom one of the maps the other maps will follow. The tool also includes a handy function to adjust the size of each of the four different map views. If you click and drag the red circle in the middle of the four maps you can expand any of the maps.
If you want to change the base map view of any of the maps simply drag the red circle to expand an individual map to full-screen. This will reveal the map's navigation and map controls.
