Re:Earth, a WebGIS platform requiring limited coding, was released in 2021 by Eukarya, a Tokyo-based group that began in the lab of longtime Cesium community member Dr. Hidenori Watanabe; the group is focused on knowledge sharing and disaster prevention.
Re:Earth supports various data formats, like CSV, GeoJSON, CZML, KML, glTF, OBJ, and FBX. Users add their datasets to Cesium ion, where they are stored and tiled into 3D Tiles and streamed to CesiumJS to make visualization and sharing easy. Re:Earth also accesses Cesium World Terrain and Bing Maps Aerial imagery in Cesium ion.
