  3. 3. Overview 3 “HeritageTogether is a project that aims to create 3D models of megalithic monuments (such as standing stones and burial chambers) in Wales, UK, from crowd-sourced images. Members of the public upload their photographs of the sites to the project website. Models are created using an open source Structure-from-Motion (SfM) work flow”
