ORLANDO -- When some of Iraq's most historic sites were destroyed by war, Ben Kacyra decided to sell his civil engineering company and start a nonprofit in 2003 with the mission of digitally preserving cultural heritage sites throughout the world with 3D laser imaging.
Kacyra, an Iraqi-born U.S. citizen, is providing the open access to those images through his organization, CyArk (short for Cyber Ark).
In the U.S., CyArk has already created 3D digital images of Mount Rushmore, Spanish missions in Texas, and Tudor Place, home to six generations of George Washington's family.

"We're out to build the Alexandria Library of 3D heritage data," said Tom Greaves, executive director of CyArk. Greaves is giving a presentation on the project at the SNW conference here this week.
Other sites around the world for which CyArk has already created digital images include the Leaning Tower of Pisa, the ancient Hindu temple complex at Angkor Wat, Easter Island's head statues, Inca ruins in Peru, and Thebes, the capital of ancient Egypt. Of course, not all the sites are all that ancient. Next week, CyArk will be in Australia generating a 3D digital image of the Sydney Opera House.
The images have a number of uses, from simply offering educators authentic reproductions for teaching purposes to giving architects and engineers the exacting dimensions they may need to restore or rebuild historic sites ravaged by time and man-made or natural disasters.
CyArk's 12-person team, based in Sacramento, Calif., creates the 3D digital models with laser-scanning instruments that replicate a site to within a few millimeters of accuracy.
Greaves said in an interview with Computerworld that collecting the digital images on disk drives has been expensive, and the current backup process is far to manual. Up until last September, CyArk's digitization projects had only taken 60TB of disk storage, but with more than 500 future projects scheduled, the organization expects its storage needs to grow at 30% per year over the next five years.

In fact, the organization recently upped its storage capacity to 100TB.
"Some time in the next five years we'll hit two petabytes of storage, and we certainly don't want to put two petabytes on disks," Greaves said.
Each 3D image project collects billions of data points, adding up to anywhere from 500GB to 10TB of capacity per project. Up until now, CyArk had been backing up its digital images on USB-connected hard disk drives. Once a disk was filled, it would be driven to a bank in Oakland, Calif., and stored in a safe deposit box. Of course, getting that backup drive back in the event server drive failure required someone to drive over to the bank and retrieve it. And, as Greaves noted, the disk drives had a relatively short shelf life.
