Archivists and librarians will be interested in preserving 3D models of buildings just as they currently preserve collections of antique photographs, drawings and maps. People interested in the history of places can use the model as a resource and repository for obtaining and sharing observations of structures - including ones that no longer exist or proposals that were never built. In the design and development community, city models are used to understand development alternatives.
Within the BPDA applications are focused on urban planning and design review. We won't fight the temptation to call these "Building Models" But users and contributors should keep in mind that models in this collection do not have a one-to-one relationship with Buildings (though some of them do!).Ī Platform for Multidisciplinary Research and CollaborationĪ 3D city model is useful for many types of research. It is possible to have more than one model for a given structure as observed at different times, created by different modelers at different levels of detail, as shown above. The real-world structures represented by models in the collection may exist or may be historical, proposed or completely hypothetical. The collection can have several models of the same building Levels of Detail and other Recommendations for Model Structure A Collection of 3D ModelsĪlthough we use the term Buildings when referring to the contents of the model collection and catalog, It is important to conceptualize the collection as being concerned with 3D Models that may represent buildings, building parts, groups of attached buildings, bridges, bridge parts, or free-standing walls.Open Source Format Collection and Catalog.Geodatabase Format Collection and Catalog.This document explains the basic concepts and purposes of the collection and catalog for users who wish to use or contribute to the model catalog.
