Add vector tiled layer from custom style

Load an ArcGIS vector tiled layers using custom styles.

Use case

Vector tile basemaps can be created in ArcGIS Pro and published as offline packages or online services. You can create a custom style tailored to your needs and easily apply them to your map. 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

Pan and zoom to explore the vector tile basemap. Select a theme to see it applied to the vector tile basemap.

How it works

1. Create an ArcGISVectorTiledLayer with the URL of a custom style from AcrGIS Online.
2. Alternatively, create an ArcGISVectorTiledLayer by taking a portal item offline and applying it to an offline vector tile package: i. Create a PortalItem using the URL of a custom style.
   ii. Create an ExportVectorTilesTask using the portal item.
   iii. Get the ExportVectorTilesJob using ExportVectorTilesTask.makeExportStyleResourceCacheJob(itemResourceCacheURL:).
   iv. Start the job using Job.start().
   v. Create a VectorTileCache using the path of the local vector tile package.
   vi. Once the job is complete, create an ArcGISVectorTiledLayer using the vector tile cache and the ItemResourceCache from the job’s result.
3. Create a Basemap from the ArcGISVectorTiledLayer.
4. Assign the basemap to the map’s basemap.
