Earth 3D Maps is a Chrome extension that allows you to explore bird's eye maps of cities and popular attractions. With this extension, you can travel virtually around the Earth and get a unique perspective of different locations.

The extension features a list of popular attractions, and when you click on a location, you are presented with a bird's-eye interactive map. This view provides an elevated perspective as if you were a bird, giving you a 3D model of the city or place.

You have the ability to zoom in and out, rotate the view by 90 degrees, and move around on the maps. Additionally, there is a search box that allows you to find specific locations on Earth.

If you want to view the map on a larger scale, you can click the "Open larger map" button, which opens the map on an external website.

Overall, Earth 3D Maps is a great tool for planning your next vacation or exploring different cities and places on Earth.

Note: This extension uses Bing Maps API and Google Maps API.
