3d Data Sources

Use MapTiler for both layers:

• terrain-quantized-mesh-v2: elevation encoded as Cesium quantized-mesh terrain.
• satellite-v2: raster satellite imagery draped on that mesh.

CesiumJS renders the layers; it does not supply the data. Set REMOTION_MAPTILER_KEY.

City

Use Google Photorealistic 3D Tiles. Google supplies one high-resolution 3D mesh already textured with imagery. Disable the Cesium globe and do not add MapTiler terrain or satellite beneath it. Set REMOTION_GOOGLE_MAPS_API_KEY.

Create and configure a key:

• https://developers.google.com/maps/documentation/tile/get-api-key (opens in a new tab)

Enable the Map Tiles API in a billing-enabled Google Cloud project and restrict the key to that API. The application restriction must permit the local headless Remotion request.

Why not extruded buildings

OSM-, Overture- and vector-tile building products primarily provide footprints, approximate heights and optional roof attributes. They are useful for analytical or stylized maps, but they do not provide the textured architecture required for a cinematic city flyover.
