An Archival Framework for Sharing of Cultural Heritage 3D Survey Data: OpenHeritage3D.org

Abstract

Abstract. Photogrammetry and LiDAR have become increasingly accessible methods for documentation of Cultural Heritage sites. Academic and government agencies recognize the utility of high-resolution 3D models supporting long-term asset management through visualization, conservation planning, and change detection. Though detailed models can be created with increasing ease, their potential for future use can be constrained by a lack of accompanying topographic data, data collector skill level, and incomplete recording of the key metadata and paradata which make such survey data useful to future endeavors. In this paper, informed by various international survey organizations and data archives, we present a framework to record and communicate Cultural Heritage - focusing on architectures based on 3D metric survey - to first describe the data and metadata which should be included by surveyors to enable data usage and to communicate the expected utility of this data.
