## Raster Tile Layer
107
+
108
+
Raster layers are used to show satellite and aerial imagery. They allow you to work interactively directly with massive, image collections stored in .pmtiles (in raster format) or Cloud Optimized GeoTIFF format.
109
+
110
+
Supported URL templates:
111
+
112
+
- Users can reference remote **.pmtiles files in raster format** for raster layers by supplying a direct link to the file.
113
+
114
+
-**Cloud-Optimized GeoTIFFs (COG)** can also be used in raster layers by providing standardized Spatio-Temporal Asset Catalog (STAC) metadata.
115
+
- The metadata file must be a valid *STAC Item* or *STAC Collection*, version 1.0.0 or higher.
116
+
- Raster data referenced in STAC assets should be Cloud-Optimized GeoTIFFs and need to be publicly accessible via HTTPS.
117
+
- STAC item and collections *must have Electro-Optical and Raster extensions*, and at least one asset must have both eo:bands and raster:bands information. common_name must be provided in eo:bands and data_type must be provided in raster:bands.
118
+
- Users must use their own instances of raster tile servers, such as Titiler. [TODO: add instructions]
