Whether you have imagery, terrain, 3D buildings, point clouds, photogrammetry, or one of the many other types of data we support, ion creates what we refer to as an asset. There are seven types of assets: | Value | Description | | - | - | | 3DTILES | A [3D Tiles](https://github.com/CesiumGS/3d-tiles) tileset | | GLTF | A [glTF](https://github.com/KhronosGroup/glTF/tree/master/specification/2.0) model | | IMAGERY | An TMS and WMTS compatible imagery layer | | TERRAIN | A [quantized-mesh-1.0](https://github.com/CesiumGS/quantized-mesh) terrain tileset | | CZML | A [CZML](https://github.com/AnalyticalGraphicsInc/czml-writer/wiki/CZML-Guide) dataset | | KML | A [KML](https://developers.google.com/kml) or KMZ dataset | | GEOJSON | A [GeoJSON](https://geojson.org/) dataset | The Assets API provides a mechanism to discover, create, and stream these assets into your own applications.
