The technological advancement of software and hardware and the lowering of the prices of instrumentation has made photogrammetry the preferred instrument for surveying activities in archaeological projects. Consequently, archaeological datasets have been enriched with 3D models of archaeological finds and structures. Each project has developed its work pipeline for raw data acquisition and the elaboration of models and their archiving and dissemination. In most cases, the pipeline is the result of empirical experimentation and is designed to act within the specific context of the project. To date, we still lack a shared method for a photogrammetric survey that derives from the specific design and techniques/contexts. This paper aims at proposing an approach for a shared 3D survey workflow for photogrammetry in archaeology. The general approach relies on the digital data curation framework for cultural heritage and encompasses several specialized tasks. We describe the general functions and processes and how they can be implemented in a practical workflow. As a proof of concept, we show how a preliminary release of the workflow has been applied in the context of the BeArchaeo project, for the acquisition, processing, export, modeling, archiving, and indexing of 3D models, resulting from photogrammetric surveys. A long-term aim is a methodological approach for different endeavors of cultural heritage.
