Several technologies were used to document the Moseley Homestead to allow for archival preservation of the site and to produce a digital “twin” and historic building information management database for the site.
The Digital Heritage and Humanities Collections team of 3D Researchers with the USF Libraries used high resolution imaging and 3D laser scanning at various scales to capture dimensional details and geometry of objects and structural aspects of the site. These tools allow for exacting models and measured drawings of the built environment, and close range 3D and imaging of select objects and features at the site afford researchers the ability to forensically study conditions and conservation needs, and develop immersive online and interactive ways of sharing and learning.
In addition to the imaging and 3D work, aerial drone surveys were conducted across the extent of the property and were done in conjunction with GPS land survey to add ground control points. These methods allow us to assemble our data into 3D models and to have detailed understanding of the terrain and elevation at the site. These types of surveys are important for a number of reasons, including site level understanding of contour and terrain elevation, and are useful for visualization and development of 3D site models and data used in a Geographic Information System for mapping and structural condition inspection. For example, our drone-based mapping allowed for detailed roof inspection on all the structures, and we were able to create 3D measurement data that was used to consider structural stability and stabilization and restoration needs more accurately.
Standard and high-resolution imagery was used to capture objects and artifacts, and digitization of select materials to support the scope of our efforts were performed with documents and materials such as historic photographs archived on site. Other imaging strategies included 360 photography used to develop a virtual tour for the site, photogrammetry methods for creating 3D models from photographs of objects, and gigapixel imagery that allow for high-resolution panoramic images to be made of site elements and environmental areas.
