Extensive three-dimensional datasets now cover most of the earth with detailed terrain, structures, and transportation networks as they exist contemporaneously. What the world looked like in the ancient past, near the beginnings of human civilization, is more difficult to discover, search, and visualize in a consistently organized temporal and geospatial fashion. UNICiv is built on the Cesium open source 3D Tiles standard to accommodate heterogeneous datasets and leverages visualization in Unreal Engine. UNICiv is an extensible, universal, spatiotemporal interface into the extant 3D modeled structures of the distant past.Attribution 4.0 International LicenseCCS Concepts: Computing methodologies → Computer graphics; Human-centered computing → Geographic visualizationComputing methodologies → Computer graphicsHuman centered computing → Geographic visualization10.2312/gch.202412488 pages
