LiDAR Recordation Techniques for Cultural Resources: Selecting an Application for Your Project
This presentation reviews and illustrates the wide application spectrum of LiDAR technologies for use in cultural resources projects. Depending on the feature or object to be scanned in the field, aerial, terrestrial and drone data each deliver different final products. The instructors will discuss methods for selecting a project-specific approach, the setup of the recordation event, and how to achieve the visualization outcome desired for the project. The lecture will include case studies from cultural resource projects. The instructors will discuss the steps to consider, including how to “look” at the object to be recorded in three dimensions and estimate how to perform the scan to achieve and produce the final 3D object. They will review the use of engineering-grade LiDAR, iPhone LiDAR, and photogrammetry-based LiDAR, as well as some common mistakes to avoid in collecting and processing 3D data.
