# Mapping Alcatraz: Bringing the Infamous Prison to Life Digitally
## Key Benefits at a Glance
| **Aspect** | **Description** |
|-------------------|---------------------------------------------------------------------------------------------------|
| **Accessibility** | Remote and previously unreachable areas of Alcatraz were explored with zero risk to personnel using the Elios 3 drone. |
| **Safety** | Teams were kept away from hazardous environments like confined spaces and wastewater storage, thanks to the drone's capabilities. |
| **Data Quality** | The Elios 3's LiDAR technology provided crystal-clear visuals, contributing to a comprehensive digital record of the entire island. |
| **Reporting** | The project findings are now being leveraged to plan Alcatraz's management and protect it from threats posed by climate change and tourism. |

Pete Kelsey, a renowned storyteller in the U.S., has been pioneering the use of drones for mapping and digitizing cultural and historical sites. His work spans from uncovering the mysteries of Pearl Harbor to exploring the enigmatic Skinwalker Ranch. For over a decade, Pete’s dream has been to create a fully digitized national park. Among the 63 national parks in the U.S., he chose Alcatraz Island—a site steeped in history and significance.

## Digitizing a National Treasure
Alcatraz, located just off the coast of San Francisco, served as a fortress-like prison from the 1930s until its closure in the 1960s. Known for its impenetrable design, it has been a cornerstone of American history. After its decommissioning, Alcatraz became part of the Golden Gate National Recreation Area and opened to the public in 1973. Today, it is managed by the National Park Service and attracts over a million visitors annually.
However, this popularity and environmental challenges—such as rising sea levels and increased foot traffic—pose significant risks to the island’s delicate structures. To preserve Alcatraz for future generations, Pete Kelsey proposed a bold initiative: digitizing the entire island. This ambitious project aimed to create a virtual representation of Alcatraz that could aid in its preservation, support archaeological research, and offer immersive experiences for those unable to visit in person.

## Assembling a Dream Team
Securing the necessary permits for the project took Pete nine months, given the strict regulations surrounding drone usage in national parks. Once authorized, he assembled a diverse team of volunteers from across the globe, each contributing specialized expertise.
Matt MacKinnon from UAS Inc., an expert in drone-based LiDAR scanning, joined the team. Just days before the project began, he suggested bringing the Elios 3 drone, citing its ability to navigate tight spaces safely. Though Pete had never worked with the Elios 3 before, he trusted Matt’s recommendation.
For three weeks, Pete and the team of dedicated volunteers mapped every corner of Alcatraz, from its rugged cliffs to its historic buildings. Sleeping in old jail cells, they worked tirelessly, united by a shared vision.

## Unveiling Alcatraz’s Hidden Secrets
One of the most remarkable applications of the Elios 3 was in the island’s powerhouse—a structure that had been closed to the public for decades. Equipped with aging boilers, chimneys, and HVAC systems, this space was fraught with hazards. Traditional methods of data collection were impossible here. The Elios 3, however, proved indispensable.
Equipped with LiDAR sensors, the drone effortlessly navigated the cramped quarters, capturing detailed scans of the interior. Pete and his team also ventured into a sealed-off area behind a barred door, discovering a civil war-era dungeon for the first time in decades. Using the Elios 3, they created a 3D model of the space, exciting the archaeological team.
Another challenge arose when a park ranger requested an inspection of two ancient cisterns. Accessible only through narrow manholes, these subterranean concrete structures had remained unexplored for years. Geoff Helluin, the Elios 3 pilot, successfully mapped both cisterns, revealing the intricate piping network beneath the stagnant water.

## Revolutionizing Preservation Efforts
With all data collected, Pete merged it using a supercomputer from AMD. The Elios 3 played a pivotal role in achieving this milestone.
“I had never witnessed the Elios 3 in action,†Pete reflected, “but I was blown away by its capabilities. Without it, many of these sites would remain inaccessible. It not only saved us immense time but ensured the safety of our team. The Elios 3 is truly a game-changer.â€
This groundbreaking project marks the first of its kind in the U.S., setting a precedent for digitizing national parks. By combining cutting-edge technology with traditional research methods, Pete and his team are paving the way for smarter, more sustainable preservation strategies.
