Armados con robots, láseres y drones especializados, Pete Kelsey y su equipo cartografiaron en 3D toda la isla de Alcatraz, accediendo a zonas que antes estaban vedadas.

San Francisco Bay

A team led by Pete Kelsey has completed a comprehensive 3D mapping of Alcatraz Island using advanced technologies including specialized drones, robots, and LiDAR laser mapping. These efforts have enabled access to areas of the island that were previously off-limits, such as sewer lines, cisterns, and the interior of the power plant’s smokestack. 

By utilizing a $100,000 drone and state-of-the-art scanning techniques, the team produced detailed digital models that provide researchers and scientists with unprecedented views of the site’s structures. One significant find was the rediscovery of the original Civil War-era gate to Alcatraz, which had been concealed for about a century by later construction. Through cross-sectional analysis of the 3D data, the team was able to reveal features not seen in over 100 years.

The mapping also shed new light on the events surrounding the prison’s well-known 1962 escape. The data visualized the path taken by one of the escapees, who reportedly dug out of his cell and navigated pipes leading to the roof, a route that had previously been difficult to document in such detail. Kelsey described the project as the most significant of his career, given its scope and the historical insights it has produced.



Los investigadores encuentran zonas que se creían perdidas en Alcatraz

Estamos a punto de mostrarle una parte de Alcatraz que no se ha visto en más de un siglo. Pete Kelsey fue llamado para cartografiar en 3D la infame isla, ahora amenazada por la subida del nivel del mar, usando un dron de 100.000 dólares. Así que enviamos esa cosa a algunos de los peores lugares que puedas imaginar. Líneas de alcantarillado, cisternas, hasta la chimenea de la central eléctrica. Pete y su equipo también utilizaron robots y, lo que es más importante, LiDAR, cartografía láser de última generación. tecnología, que permitió al equipo esencialmente ir atrás en el tiempo y capturar datos que pueden salvar el futuro de Alcatraz. Piensa en ello como una radiografía o un TAC de toda la isla, y ahí es donde mucho de descubrimiento potencialmente puede venir, es cuando se puede dar a los científicos, investigadores, académicos una visión que nadie ha visto antes. Así que lo que estamos viendo es un edificio moderno, sólo unos 100 años de edad, que colinda, que está justo al lado de la puerta original de Alcatraz de la época de la Guerra Civil. Y debido a que fueron construidos una al lado de la otra, esta señal original sobre la puerta fue bloqueada, literalmente bloqueado. Así que cortando una sección transversal a través de estos datos, como vemos aquí, vemos una vista que nadie ha visto en más de 100 años. Los descubrimientos del equipo también han levantado el velo sobre la famosa fuga de la prisión en 1962. Y aquí es donde este uno de los tres chicos cavó su camino fuera de su celda en este corredor. Luego treparon por todas estas tuberías. Cada noche durante semanas, venían aquí y empezaban construyendo cosas que necesitaban para la fuga, hasta que la noche de la fuga, salieron por este conducto de ventilación hasta el techo. He estado haciendo este tipo de trabajo durante décadas y literalmente en todo el mundo. Este proyecto, sin embargo, creo que podría ser mi Mona Lisa.
