Abstract
The recent Japanese earthquake and tsunami is one of several recent, destructive events that has provided critical engineering information regarding the performance of buildings, bridges, walls, roadways, etc. during intense loading. 3D laser scanning technology provides a valuable tool to acquire perishable information and preserve the scene digitally for post-disaster assessment. This paper discusses the challenges and benefits for use of 3D laser scanning on post-disaster reconnaissance efforts. This paper also focuses on special considerations when performing scanning work in post-disaster environments. Because of the limited time available to make critical decisions, it is important for personnel to know optimal procedures during planning, field reconnaissance, collaboration, data acquisition, processing, and analysis. Examples from recent events illustrate the power of this revolutionary tool in forensic investigations.
