The gigapixel image concept for graphic SEM documentation. Applications in archeological use-wear studies

• Gigapixel-like images are created using SEM micrographs.
• Use-wear traces can be studied at different scales with mosaic compositions.
• Gigapixel-like SEM images are a useful tool for teaching microscopy observation.

In this paper, we propose a specific procedure to create gigapixel-like images from SEM (scanning electron microscope) micrographs. This methodology allows intensive SEM observations to be made for those disciplines that require of large surfaces to be analyzed at different scales once the SEM sessions have been completed (e.g., stone tools use-wear studies). This is also a very useful resource for academic purposes or as a support for collaborative studies, thus reducing the number of live observation sessions and the associated expense.
