POINT CLOUD APPLICATIONS FOR DISASTER REMEDIATION: A CASE STUDY

Photorealistic, LiDAR-based 3D imaging provides accurate and precise documentation of existing conditions and measurable geometry. The quality and accuracy of the data generated by LiDAR cannot be economically recreated using more traditional measurement and CAD techniques. While earlier forms of this technology have been used for many years, recent innovations have provided opportunities for numerous new uses that will soon change the way many professionals obtain, analyze and process data. The use of 3D scanning equipment for new applications is gaining momentum and one such application, its use for disaster mitigation, was explored in a case study. The study reviews scanning industry applications and improvements for precision and also includes a case study in the application of a historic church post disaster, which was documented with the beneficial applications (such as safety and time savings) as well as what the authors believed to be future research areas for similar projects.
