# Flyover data sources
|
|
|
|
## Landscape
|
|
|
|
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`.
|
|
|
|
Create a key:
|
|
|
|
- https://cloud.maptiler.com/account/keys/
|
|
|

|
## 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
|
|
|
|
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.
