WmtsTiledOverlay¶

Namespace: ThinkGeo.Core

Represents an overlay object that gets map images from the WMTS server you specify.

public class WmtsTiledOverlay : WebBasedTileOverly`1, System.IDisposable

Inheritance Object → Overlay → TileOverlay → WebBasedTileOverly<WmtsLayer> → WmtsTiledOverlay
Implements IDisposable

Remarks:

The WmtsOverlay gets images from one or more WMTS servers that you specify. Usually, you add a WMTS server URI to the ServerUris collection and the WmtsOverlay will make a request to that WMTS server to get its tile images.

You can also add multiple WMTS server URIs to the ServerUris collection. The WmtsOverlay will randomly send requests to those WMTS servers in a concurrent fashion. This means that the tile images can come from different WMTS servers, thus greatly enhancing performance. Do not add URIs of differently-configured WMTS servers to the ServerUris collection.
