This document discusses a project called HeritageTogether that aims to create 3D models of megalithic monuments in Wales using crowdsourced photos from the public. The project addresses challenges facing archaeologists in thoroughly surveying over 2,500 sites due to limited time and resources. Through the HeritageTogether website, members of the public can upload photos of sites which are then processed into 3D models using photogrammetry and structure-from-motion techniques. The models are made available online and the project engages both the public and academics to record and analyze cultural heritage assets through digital means.
