Technical considerations and methodology for creating high-resolution, color-corrected, and georectified photomosaics of stratigraphic sections at archaeological sites

Here, we provide a detailed discussion about the creation and application of our photomosaics. In the first part of the paper, we examine the specific characteristics of modern digital single lens reflex (DSLR) cameras and lenses that were important to us in developing our methodology. We also provide a detailed discussion about how to reproduce the methodology in the field and to post-process the imagery. In the final section of the paper, we give several examples to show how we apply our photomosaics within an empirical 3D GIS database. These examples are provided to show how photographic data can be integrated with other digitally-captured data and used to study the relationships between the stratigraphic features seen in the photomosaics and the 3D distribution of excavated archaeological piece-plots, geochronological samples, and other kinds of geological samples.
