Description
CyArk was founded in 2003 to ensure heritage sites are available to future generations, while making them accessible today. CyArk operates internationally as a non-profit organization with the mission of using new technologies to create a free, 3D online library of the world's cultural heritage sites before they are lost to natural disasters, destroyed by human aggression or ravaged by the passage of time. CyArk uses cutting edge technology to capture detailed 3D representations of world’s significant cultural heritage sites before they are lost to natural disasters, destroyed by human aggression or ravaged by the passage of time.
