Re:Earth Buildings is an open 3D building tile service built from Overture Maps and Re:Earth Terrain. Just point any 3D Tiles 1.1 compatible client (such as Cesium) at the URL below to use it.
https://buildings.reearth.land/tileset.json
import * as Cesium from "cesium";
const viewer = new Cesium.Viewer("app");
const buildings = await Cesium.Cesium3DTileset.fromUrl(
"https://buildings.reearth.land/tileset.json",
);
viewer.scene.primitives.add(buildings);
// Recommended: pair with Re:Earth Terrain so building footprints sit cleanly on the ground.
viewer.scene.setTerrain(
new Cesium.Terrain(
Cesium.CesiumTerrainProvider.fromUrl(
"https://terrain.reearth.land/cesium-mesh/ellipsoid",
{ requestVertexNormals: true },
),
),
);
ODbL 1.0 requires you to display the attribution below somewhere
when the data is shown. Most clients (including Cesium) surface
asset.copyright from tileset.json
automatically; if yours doesn't, add it to your credits manually.
Buildings: Re:Earth Buildings, OpenStreetMap contributors, Overture Maps Foundation (ODbL). Terrain: Re:Earth Terrain, Mapterhorn.
Operated by Eukarya Inc. as part of the Re:Earth ecosystem.
Heights: where the source data provides a height we use it; otherwise we estimate one from footprint area, neighbours, and land use. Estimated heights are plausible but not accurate — don't use them for analysis that depends on real building dimensions.
Note: this is a best-effort community service with no SLA or uptime guarantee. Use at your own risk, and please don't rely on it for production traffic without hosting your own mirror.
