Web tiled layer

Display a tiled web layer.

How to use the sample

The web tiled basemap will load automatically when the sample starts.

How it works

  1. Create a WebTiledLayer from a URL and a list of subdomains.
  2. Create a new Basemap from the layer.
  3. Update the attribution on the layer. Note: this is a necessary step because web tiled services don't have associated service metadata.
  4. Display the basemap.

Relevant API

  • Basemap
  • WebTiledLayer

About the data

The basemap in this sample is provided by Stamen Design. Stamen publishes tiled services based on OpenStreetMap data with several unique styles applied.

Additional information

Web tiled services use a uniform addressing scheme with pre-rendered tiles. Image tiles are accessed via a URL template string, with parameters for subdomain, level, column, and row.

  • Subdomain is optional and allows Runtime to balance requests among multiple servers for enhanced performance.
  • Level, row, and column select the tiles to load based on the visible extent of the map.
