Load an ArcGIS Vector Tiled Layer from a URL.

Use case

Vector tile basemaps can be created in ArcGIS Pro and published as offline packages or online services. ArcGISVectorTiledLayer has many advantages over traditional raster based basemaps (ArcGISTiledLayer), including smooth scaling between different screen DPIs, smaller package sizes, and the ability to rotate symbols and labels dynamically.

How to use the sample

Use the drop down menu to load different vector tile basemaps.

How it works

  1. An ArcGISVectorTiledLayer is constructed with an ArcGIS Online service URL
  2. The layer instance is added to the Map
