“Why don’t you just use a technician?”

Posed at a recent conference of the Southeast Chapter of the Society of Architectural Historians, this question was puzzling and, admittedly, a bit exasperating. Nonetheless, this is not the first encounter with skepticism concerning digital documentation techniques for architectural research. The conference session “The Digital Lens on the Past” centered on the use of digital technologies to record and represent aspects of built heritage, with emphasis on indicating a fourth dimension: time. This included the visualization of ruined or lost elements, unrealized interiors (e.g., Longwood in Natchez, Mississippi), rates of decay at heritage sites in severe peril, and seasonal changes in constructed landscapes.1 If formulated differently, it is not difficult to imagine that the attendee’s question would have instantly perplexed the room of architectural historians, cultural resource managers, and preservation professionals: why not hire someone to autonomously complete an analog survey of a building or site? That person could pass along the information, and the scholar would then advance all subsequent study and analysis. Between the two parties, there would be a linear and sequential project path, albeit entirely independent: technical data input and output from research professionals. In short, the conference attendee’s question placed elements of documentation practice and architectural scholarship at odds. If it is difficult for most professionals in the built environment to envision the success of a project in which analog survey and on-site experience are divorced from research and analysis, why has a hierarchical divide emerged with reference to digital documentation? This essay argues that when fully integrated into the discovery and analysis phases of a project, digital documentation is a valuable, reliable, and exploratory practice that can combine information about the physical aspects of the built environment with additional archival, experiential, and technical layers.

The incorporation of reality capture—the use of technical means to record and visualize elements from the physical world—offers new veins of exploration and analysis for the built environment, and it has been used in architectural history for decades. Yet there are ongoing hesitations and misinterpretations about the use of digital technology for documentation in the built environment. Foremost, digital documentation is viewed as a tool rather than a methodology, and some view its products solely as visualizations. Examples of digital documentation include 3D scanning, photogrammetry, and 360 imagery captures; each offers a different way of documenting, visualizing, and studying a site, but they all require additional tools and software (Figures 1–3). Architects, architectural historians, and [End Page 2] preservation professionals are familiar with the “fieldwork tool bag,” filled with measuring and drawing instruments. In the 1980s, enhanced geolocation technologies such as total-station theodolites (TST) and global positioning systems (GPS) joined the study of historic environments. In the 1990s, additional allied specializations such as paint analysis and dendrochronology (as well as broader approaches to architectural history) advanced surveys from strictly artifactual biographies to broader studies that examined historical explanations of material culture, community, and social contexts.2 Rather than a singular researcher with a measuring tape, architectural scale, and gridded sketchpad, fieldwork became a team practice that was dependent on physical artifacts (e.g., structures), an expanded array of primary sources, and the expertise of several researchers and practitioners. In the twenty-first century, that fieldwork tool bag and team need to get a little bigger, and more expensive; with these new complexities in cost and logistics, however, come new opportunities for documentation and dissemination.

Interpretative Recording Methods

Digital documentation is not only an asset for field surveys, but also an essential method for the future of heritage sites with reference to advocacy, accessibility, preservation practice, and research dissemination. When used as an integrated method within a multifaceted team, digital documentation can enhance on-site work, facilitate deeper investigations, and lead to unique products that are useful for long...
