Mission Santa Inés Captured on 3-D as High School Students Take Technology to New Level

Innovative imaging program connects Santa Ynez High with global effort to digitally preserve historical sites

Students hid behind pepper trees at Mission Santa Inés in Solvang on a recent Friday morning as they took images and scanned structures for their one-of-a-kind project involving a 3-D laser.

A group of students in the Environmental and Spactial Technologies (EAST) program at Santa Ynez Valley Union High School are the first high school students in the world using Laser Imaging Detection and Ranging (LiDAR), which rapidly captures millions of points to construct a 3-D image of an object.

“This technology allows us to reconstruct objects, buildings and other things that are historic and valuable so in case anything happens like a fire or flood, it can be recreated,” said McKensey Richmond, a junior in the program.

After watching a TED talk about the laser technology, Superintendent Paul Turnbull got together with teacher Chip Fenenga and Santa Barbara County Regional Occupation Program (ROP) director Tony Bauer to introduce the technology at the school. Created by CyARK, an Oakland-based nonprofit organization, the objective is to digitally preserve cultural heritage sites by collecting, archiving and providing access created by laser scanning, digital modeling and other state-of-the-art technologies.

“With this laser scanner and software you can literally fly through and around structures or objects and it has an accuracy down to the millimeter,” Fenenga told Noozhawk. “The opportunity these students have with this is amazing because it provides hands-on experience that is way ahead of the field.”

Stephanie Aichinger, a Santa Ynez High senior, is considering attending Cal Poly San Luis Obispo as an architecture major, especially since she has had been using the EAST program to document the mission, the mission’s Grist Mill for the Santa Barbara Trust for Historic Preservation and horse carriages for the Santa Ynez Valley Historical Society.

“To be able to preserve these historical pieces for the future is so cool to be a part of,” Aichinger said. “The aspect of architecture I like is how building design mimics the society and people of that era, so this project fits those together.”

The laser scanner is positioned up to 43 yards away from the object and rotates to capture more than 1 million measurements every minute. The scanner also takes color pictures of the scan area and maps the color or texture information.

“We then take the scans and put them together into the program and select what we don’t want, like shadows or people walking through the area,” said Alice Mullin, a senior student involved with the project. “Once the image is cleaned up, the 3-D model is created.”

CyArk is using this technology for its worldwide CyArk 500 Challenge, which is to digitally preserve 500 of the most important world heritage sites over a five-year period. Sites include the pyramids in Egypt, the Great Wall of China, the Eiffel Tower in Paris, Mayan ruins and many other notable places.

The LiDAR technology has application in fields like agriculture, archaeology, atmospheric physics, forensics, forestry, geology, geomorphology, military and law enforcement, mapping and remote sensing.

“Our hope it to make this technology available to the community so they can essentially borrow the laser and use it for many things, like scanning local archaeological sites, in forensic cases scanning crime scenes or mapping trail systems,” Fenenga said.

Fenenga noted that UC Santa Barbara and Cal Poly don’t have the technology and he said he hopes the school can work with them in the future.

Noozhawk Asks: What’s Your Question?

Welcome to Noozhawk Asks, a new feature in which you ask the questions, you help decide what Noozhawk investigates, and you work with us to find the answers.

Here’s how it works: You share your questions with us in the nearby box. In some cases, we may work with you to find the answers. In others, we may ask you to vote on your top choices to help us narrow the scope. And we’ll be regularly asking you for your feedback on a specific issue or topic.

We also expect to work together with the reader who asked the winning questions to find the answer together. Noozhawk’s objective is to come at questions from a place of curiosity and openness, and we believe a transparent collaboration is the key to achieve it.

The results of our investigation will be published here in this Noozhawk Asks section. Once or twice a month, we plan to do a review of what was asked and answered.

Thanks for asking!
