#### Cloud Optimized GeoTIFF (COG)

cog 15

#####

Rendering a COG as a tiled layer.

Tiled data from a Cloud Optimized GeoTIFF (COG) can be rendered as a layer. In this example, a single 3-band GeoTIFF is used to render RGB data.

##### main.js

    import Map from 'ol/Map.js';
    import {getView, withExtentCenter, withHigherResolutions} from 'ol/View.js';
    import TileLayer from 'ol/layer/WebGLTile.js';
    import GeoTIFF from 'ol/source/GeoTIFF.js';

    const source = new GeoTIFF({
      sources: [
        {
          url: 'https://sentinel-cogs.s3.us-west-2.amazonaws.com/sentinel-s2-l2a-cogs/36/Q/WD/2020/7/S2A_36QWD_20200701_0_L2A/TCI.tif',
        },
      ],
    });

    const map = new Map({
      target: 'map',
      layers: [
        new TileLayer({
          source: source,
        }),
      ],
      view: getView(source, withHigherResolutions(1), withExtentCenter()),
    });
