Abstract

The Sand Atlas is a publicly accessible repository dedicated to the collection, processing, and sharing of high-resolution 3D models of sand-sized particles. This dataset offers valuable insights into the morphology of a wide variety of natural and synthetic sand-sized particles from different regions, with varying mineralogy and history. The primary goal of The Sand Atlas is to support researchers, educators, and industry professionals by providing detailed, easily accessible and uniformly produced surface meshes and level-set data. The underlying code that converts volumetric data to meshes is also available via the sand-atlas python package. This platform encourages community participation, inviting contributors to share their own data and enrich the collective understanding of granular materials.
