Felt connects directly to raster data cloud storage, with support for [Cloud Optimized GeoTIFFs (COGs)](/data-sources/raster-infrastructure/cloud-optimized-geotiffs.md) and [Spatio-Temporal Asset Catalogs (STACs)](/data-sources/raster-infrastructure/stac.md). Your raster data is streamed in place, indexed for location and metadata filtering, and made available for immediate [visualization](/layers/styling/raster-layers.md) without moving or duplicating files.

For guidance on preparing your data for use in Felt, see [Organizing your raster data](/data-sources/raster-infrastructure/organizing-your-raster-data.md).
