XYZ raster tiles
Add XYZ, TMS, or WMTS raster tiles to Felt with a template URL containing {z}, {x}, and {y} placeholders.
An XYZ tile service supplies small images that form a map, such as aerial imagery or a historical map. Add its template URL to Felt to create a raster layer. To use tiles as the basemap beneath all layers instead, see Basemaps.
Add a tile layer
In the toolbar, click Upload Anything
> From URL.Paste the template URL. Felt checks it and shows Looks good.
Click Add to map. The raster layer appears in the legend.
To change the layer's opacity or colors, see Style raster layers.
Template URL format
An XYZ template URL must contain these three placeholders, in any order (ArcGIS tile services, for example, use /{z}/{y}/{x}):
{z}for the zoom level{x}for the tile column{y}for the tile row, or{-y}for services that number rows from the bottom, in Tile Map Service (TMS) order
A URL can also use {s} for a subdomain. The tiles must be images, but the URL doesn't need to end in .png or .jpg. Replace any other placeholder, such as {apikey}, with its value, or Felt shows No value provided for parameter. WMS services don't work as tile templates; add them as a WMS / WMTS service instead.
Anyone who can view the map can see the tile URL, including any API key in it. Every map view requests tiles and can add provider costs. Restrict the key to your own domains where supported.
This example is a map of Aberdeen from the National Library of Scotland, in TMS order:
