--- layout: example.html title: GeoTIFF tile pyramid shortdesc: Rendering a COG tile pyramid as layer group. docs: > Data from a Cloud Optimized GeoTIFF (COG) tile pyramid can be rendered as a set of layers. In this example, a pyramid of 3-band GeoTIFFs is used to render RGB data. The `ol/source.sourcesFromTileGrid` helper function creates sources from this pyramid on demand. The GeoTIFFs used by those sources have a resolution range that matches the range of a single z of the pyramid tile grid. tags: "cog, tilepyramid, stac" ---
