Often considered the birthplace of Queensland's military history, Fort Lytton is a coastal fortress at the mouth of the Brisbane River that served as Brisbane's front line of defense from 1881 until the end of the 1930s. The pentagonal fort, surrounded by a water-filled moat and hidden behind grassy embankments, is a prime example of a 19th-century garrison, built to protect the minefields in the river and defend the Port of Brisbane. After World War II it was replaced by more modern batteries and abandoned. The Ampol petroleum company acquired the site in 1963, and ownership passed to the Queensland Government in 1988. It is now a national park managed by the Queensland Parks and Wildlife Service, protecting an important link to Queensland's military past.
CyArk partnered with CSIRO, the University of Queensland, the Queensland Government Department of Environment and Heritage Protection and Queensland Parks and Wildlife Service to document Fort Lytton using Zebedee, a handheld 3D laser mapping system developed by CSIRO's Autonomous Systems team. Zebedee scans continuously as its operator walks, producing a 3D map of the environment and an accurate record of the path followed.
