Web Tiled Layer

View in GitHub

Demonstrates how to display map tiles from a non-ArcGIS service as a layer in a map.

WebTiledLayer provides a simple way to integrate non-ArcGIS Services as a layer in a map. In this case, map tiles from Stamen are added to the map. The template URI is specified by setting the subDomains, level, column, and row attributes. Additionally, copyright information is added to the layer so that the layer can be properly attributed.

How it works

To create and display a WebTiledLayer with custom attribution:

1. Create a WebTiledLayer specifying the list of subdomains and a template URI.
2. After loading the layer, use webTiledLayer.setAttribution(attributionText) to set custom attribution.
