Taking a look at the items and exhibits included in our centennial project, For the Centuries, visitors will discover that we uncovered and aggregated a wide range of materials for the site. While many of the digital objects on the site tell stories or have special significance all by themselves, other objects and data needed a bit of interpretation. Take graduate hometown data, for example: a spreadsheet of dates and places doesn’t say much, but if the locations are mapped and interactive as they are in our hometowns exhibit, patterns of student geographic distribution can easily be seen over time. This post is about another example of such interpretation – the conversion of a number of physical items into digital files, and the creation of something new.
The good folks at the Virginia Baptist Historical Society pointed us toward an undated topographic survey map of the campus area. Based on the building footprints present on the map, we believe that it dates to 1911, the year following Ralph Cram’s initial General Plan.
We quickly realized that this single item provided the foundation for something impressive, and that when combined with data from other materials we’d gathered from University Facilities and elsewhere, we’d be able to use it to generate a three-dimensional model of the 1914 campus, complete with the initial buildings. Three departments in Information Services, Discovery, Technology and Publishing (DTP) in Boatwright Memorial Library, the Center for Teaching, Learning, and Technology (CTLT), and the Digital Scholarship Lab (DSL), had the expertise and ability to work together to pull this off.
Production of the model involved a variety of techniques and technologies. The topographic map, blueprints and photographs were imaged by DTP staff using a Phase One P65+ digital back. Students and staff in DTP and DSL then worked together to digitize the map’s topographic lines and render an elevation map file using ArcGIS. The blueprints and photographs provided the information needed to create three-dimensional models of the campus’ buildings using Sketchup. (Be sure to check out this post, by Justin Madron of the DSL, about the techniques used to accomplish this.) In the CTLT, the elevation map and building models were merged into a single 3D object using Sketchup Pro and printed on a 3D Systems ProJet 460Plus printer.
Several student employees contributed in important ways to this project. Stefan St. John (DSL) georectified the maps used for this project. Jackie Palmer (DTP) digitized the survey map’s topographic lines and campus features. Jackie and Lily Calaycay (DSL) worked together to model the campus buildings from data embedded in source documents. Selmira Avdic, Francisco Cuevas, Lisa Hozey and Umurcan Solak (CTLT) assisted with the 3D printing and tile finishing process.
The completed model, now on display on the second floor of Boatwright Library, depicts the campus as it was on opening day in 1914, and serves to demonstrate the relative scale of the buildings and topography of the grounds. Reproductions of contemporary photographs of each building are distributed around the model. Come by Boatwright to see the results of our collaboration.
