Dual Maps is a map creation tool that allows anybody to make an embeddable map that includes a Google Map, a Google Maps Street View and a Virtual Earth Bird's Eye view of the same location. You can choose between the various options of either map service, which means you can have the Google satellite view alongside Virtual Earth's Bird's Eye view or the satellite/aerial View in both maps etc..
Dual Maps now comes with a couple of new features. It is possible to add a Google search bar to a Dual Map, which means users can search for local businesses from the map. It is also possible to choose from a number of marker styles in the Street View map. You can choose between the traditional pegman, a panda, a car or Gachapeg.
Bird's Eye View
This map places Bing Maps' Bird's Eye View side by side with Google Maps' new Aerial View. At the moment Google's Aerial View imagery in Google Maps Labs is limited to only a few cities in the USA.
However as Google expands their imagery this map mashup will expand to reflect the new aerial view available.
