Class WebTiledLayer
A layer that requests image tiles based on a URL template, providing a simple way to display maps from non-ArcGIS web services or local tile caches.
Inheritance
Namespace: Esri.ArcGISRuntime.Mapping
Assembly: Esri.ArcGISRuntime.dll
Syntax
public sealed class WebTiledLayer : ServiceImageTiledLayer, INotifyPropertyChanged, ILoadable, ILayerContent
Remarks
This layer provides a simple way to integrate non-ArcGIS Services as a layer in a map. The URL
template usually follows a pattern similar to
https://{subDomain}.server.org/path/{level}/{col}/{row}.png
, where:
- "subDomain" is one of the strings in the subDomains list
- "level" corresponds to a zoom level
- "col" represents the column of the tile
- "row" represents the row of the tile.
The URL should be arranged to reflect how the tiles are organized in the cache or on the
server, and can point to a web server (https://
) or to a local file cache
(file://
).
The tiles retrieved by this class are accessed directly by URL. Because the service is only providing images, you are responsible for manually setting the attribution text on the map or scene view.
To create a custom service tiled layer whose URL follows the above pattern (or a similar
pattern), you can extend this class. Alternatively, you can extend the super class
Service
An System.
If Tile
Functional characteristics
Tiles are fetched on demand using the specified URI template. Tiles are typically rendered and cached on the server but may be generated on demand by some services. Web tiled layers do not support identify, query, selection, or time.
Specifying sub-domains from which the layer will request tiles allows the load to be more evenly distributed among servers.
Performance characteristics
Web tiled layer requires a connection to the service at all times. Performance is similar to other raster tile layers.
