Model Behavior: Using Photogrammetry for Collections Storage Planning

Proper and efficient collections storage is often a challenge for museums. As collections outgrow their facilities, institutions struggle to find additional space, often resorting to hasty moves of their objects into ill-fitting placements. A large-scale collections move is a slowgoing process, requiring manual measurement and countless trial-and-error sessions. An unnoticed support beam, a low entryway, or uneven flooring can derail even the most well-planned collections move, costing an organization unexpected additions in time and labor expenses. Advancements in emerging technologies, however, may soon eliminate this problem. This capstone explores the use of photogrammetry and 3D modeling to plan a collections storage move in a virtual environment. It examines the relationship between museums and technology through an analysis of museum studies literature, and showcases examples from the archaeology, architecture, and design fields to demonstrate the potential of photogrammetry. A collections move project using this technology for the digital modeling of storage spaces is proposed and detailed. Through the proposed project, I argue that the use of these technologies to design collections storage will greatly optimize a collections move

The Educational Experience of Virtual Reality: An Archaeological Case Study of the Maya Site, Vista Alegre

Archaeological visualization has a long history within the discipline, relying on technological advancements to aid in recording, interpreting, and educating about sites and projects. Though computer graphics have been used as archaeological visualizations for decades, hardware advancements have begun to allow for broader consumer use of Virtual and Augmented Reality platforms in homes, schools, and museums. This thesis explores the applications of Virtual and Augmented Reality platforms for archaeological visualization, specifically in the area of public education. To this end, a 3D model and virtual experience of the Maya site of Vista Alegre in Mexico are created, methodologically explained, and examined to relate history, theory, and the goals of utilizing this medium within the archaeological discipline while expanding on the ethical requirements and empirical methods of praxis. In all, this technology both produces tangible, quantifiable, and accurate data and makes these data more accessible to the general public. Image from Proskouriakoff (1970[1946]

PRESERVING THE VERNACULAR POSTINDUSTRIAL LANDSCAPE: BIG DATA GEOSPATIAL APPROACHES TO HERITAGE MANAGEMENT AND INTERPRETATION

Redundant historical industrial sites, or postindustrial landscapes, face numerous preservation challenges. Functionally obsolete, and often derelict and decaying, these cultural landscapes often retain only a fraction of their original infrastructure. With their historical interconnections made indistinct by their physical separation and obscured by the passage of time, surviving remnants are isolated and disjunct, confounding both their legibility and their consideration for formal historic preservation. Nevertheless, they persist. This dissertation presents a theoretical understanding of the nature of postindustrial landscape preservation, and argues that the material persistence of its historical constituents is the result of previously overlooked processes of informal material conservation, here termed vernacular preservation. Further, this dissertation examines ways that heritage professionals can manage and interpret these vast, complex, and shattered landscapes, using 21st-century digital and spatial tools. Confronted by ongoing depopulation and divestment, and constrained by limited financial capacity to reverse the trend of blight and property loss, communities and individuals concerned with the preservation of vernacular postindustrial landscapes face many unique management and interpretation challenges. The successful heritagization of the postindustrial landscape depends on its comprehension, and communication, as a historically complex network of systems, and I argue that utilizing advanced digital and spatial tool such as historical GIS and procedural modeling can aid communities and heritage professionals in managing, preserving, and interpreting these landscapes. This dissertation presents heritage management and interpretation strategies that emphasize the historical, but now largely missing, spatial and temporal contexts of today’s postindustrial landscape in Michigan’s Copper Country. A series of case studies illustrates the demonstrated and potential value of using a big-data, longitudinally-linked digital infrastructure, or Historical GIS (HGIS), known as the Copper Country Historical Spatial Data Infrastructure (CC-HSDI), for heritage management and interpretation. These studies support the public education and conservation goals of the communities in this nationally-significant mining region through providing accessible, engaging, and meaningful historical spatiotemporal context, and by helping to promote and encourage the ongoing management and preservation of this ever-evolving postindustrial landscape

Reconciling the dissonance between Historic Preservation and Virtual Reality through a Place-based Virtual Heritage system.

This study explores a problematic disconnect associated with virtual heritage and the immersive 3D computer modeling of cultural heritage. The products of virtual heritage often fail to adhere to long-standing principles and recent international conventions associated with historic preservation, heritage recording, designation, and interpretation. By drawing upon the geographic concepts of space, landscape, and place, along with advances in Geographic Information Systems, first-person serious games, and head-mounted Virtual Reality platforms this study envisions, designs, implements, and evaluates a virtual heritage system that seeks to reconcile the dissonance between Virtual Reality and historic preservation. Finally, the dissertation examines the contributions and future directions of such a Place-based Virtual Heritage system in human geography and historic preservation planning and interpretation

Building Cultural Heritage Resilience through Remote Sensing: An Integrated Approach Using Multi-Temporal Site Monitoring, Datafication, and Web-GL Visualization

In the American West, wildfires and earthquakes are increasingly threatening the archaeological, historical, and tribal resources that define the collective identity and connection with the past for millions of Americans. The loss of said resources diminishes societal understanding of the role cultural heritage plays in shaping our present and future. This paper examines the viability of employing stationary and SLAM-based terrestrial laser scanning, close-range photogrammetry, automated surface change detection, GIS, and WebGL visualization techniques to enhance the preservation of cultural resources in California. Our datafication approach combines multi-temporal remote sensing monitoring of historic features with legacy data and collaborative visualization to document and evaluate how environmental threats affect built heritage. We tested our methodology in response to recent environmental threats from wildfire and earthquakes at Bodie, an iconic Gold Rush-era boom town located on the California and Nevada border. Our multi-scale results show that the proposed approach effectively integrates highly accurate 3D snapshots of Bodie’s historic buildings before/after disturbance, or post-restoration, with surface change detection and online collaborative visualization of 3D geospatial data to monitor and preserve important cultural resources at the site. This study concludes that the proposed workflow enhances the monitoring of at-risk California’s cultural heritage and makes a call to action to employ remote sensing as a pathway to advanced planning.

The Potential of Virtual Heritage Reconstruction in Lost Ansonborough

The virtual reconstruction of vanished heritage is a well-known practice in the preservation field. The constant development in computer technologies has been improving visualization and interpretation techniques for virtual reconstructions of no longer extant or inaccessible sites. Reconstruction projects of vanished heritage sites implement various approaches because of different challenges at each site. This research involves 3D reconstructions, as well as historical research of early nineteenth century residences, Radcliffe-King and Gabriel Manigault houses in the Ansonborough neighborhood of Charleston, South Carolina, USA. The demolition of these two mansions in the first half of the twentieth century leads to the loss of the residential character at the intersection of George and Meeting Streets in Ansonborough. Photogrammetry and rectification techniques established the dimensions and the scale for these buildings from salvaged architectural details and early photographs to recreate the lost residential character. Other sources, like maps and drawings are used to supplement the photographs and salvaged materials for virtual reconstruction
