Online internet users can now use Google Earth to explore the 9/11 Memorial and Museum within the context of the surrounding landscape of lower Manhattan.
National September 11 Memorial at Night
Google Earth, a satellite imagery-based mapping program, creates a virtual look at the World Trade Center site by introducing a new, dimensionally accurate 3D model that replicates key components of the Memorial and other planned projects at the 16-acre site.
To view maps in 3D you will need to download the Google Earth plugin
