Track 4: This New World: Preservation technology and emerging issues within our historic buildings and built landscapes

CS4.1 Preservation and the Digital Future

10:30 AM - 12:00 PM
Location: BNCC-106BC
CE: 1.5

With our need to continually find better ways of assessing and managing our numerous heterogeneous cultural resources, we are more often turning to emerging technologies for assistance. Unraveling an idiomatic mystery with technology that is in its infancy or perhaps not yet even in existence, necessitates custom hi-tech creativity to provide a new generation of technological solutions that promotes improved information coordination, welcomes collaboration, and allows the future to inform the past. The seeming dissonance between the past and the future; the dichotomy of using digital technology to preserve the analog past is discussed through the use of case studies and expositions on how emerging technology employs need-driven creative approaches to a lack of current applicable methods that resolve existing challenges. Open-source development, real time modeling, high-resolution photogrammetry, specialized comprehensive data collection and storage systems, and digital representations through 3-D modeling and virtual environments are several methods that are discussed.

This course qualifies for HSW credit with AIA and RCEP.
