Class WMTSTileSetModel

The base URL configures the location of the tile server. Please refer to getTileURL for details on how the base URL is used to obtain tiles.

The Bounds by which the geometry of this Bounded object is bounded or null if the bounds is not defined.

The coordinate type of geometries in this model

Indicates whether or not credentials should be included with HTTP requests.

Set this to true if the server requires credentials, like HTTP basic authentication headers or cookies. You should disable credentials if the server is configured to allow cross-origin requests from all domains (Acces-Control-Allow-Origin=*). If the server allows CORS requests from all domains, the browser will block all requests where credentials=true.

Once set, all subsequent HTTP requests will use the newly set value.

The default value is false.

Returns the data type of this RasterTileSetModel.

The number of available detail levels. Level 0 is the coarsest level.

Headers to send with every HTTP request.

An object literal that represents the headers to send with every HTTP request. The property names represent HTTP header names, the property values represent the HTTP header values. This property can be set dynamically (post-construction). Once set, all subsequent HTTP requests will use the newly set headers.

Note that when custom headers are being sent to a server on another domain, the server will have to properly respond to pre-flight CORS requests (a HTTP OPTION request sent by the browser before doing the actual request). The server has to indicate that the header can be used in the actual request, by including it in the pre-flight's Access-Control-Allow-Headers response header.

The default value is null.

Returns the sampling mode of this RasterTileSetModel.

getTileURL will replace the {s} pattern in baseURL with values from subdomains. This will cause tile requests to be spread across different subdomains. Browsers limit the amount of connections to a single domain. Using subdomains avoids hitting this limit.

The subdomains array cannot be empty if the model's baseURL contains the {s} subdomain hook.

Returns the bounds of the tile set at the specified detail level.

Since

2023.0

Loads a tile from the tileset.

Returns the pixel density of the raster data at the specified detail level. The pixel density is the number of raster elements per spatial unit , i.e. (tile pixel width) / (tile spatial width) and (tile pixel height) / (tile spatial height area), where the tile spatial dimensions are in the tilesets reference.

Returns the number of columns in the tile grid at the given level. Each level should have twice the number of columns of the previous one.

Loads a tile from the tileset. The default implementation of this method calls the getImage method.

The following code snippet illustrates how this method can be overridden.

model.getTileData = function(tile, onSuccess, onError) {
  fetch(url).then(function(response) {
    response.arrayBuffer().then(function(arrayBuffer) {
      onSuccess(tile, {
        data: arrayBuffer,
        mimeType: "image/jpeg"
      });
    })
  });
Copy

Returns the height, in pixels, of the tiles at the specified detail level. All tiles are assumed to have the same resolution.

Returns the number of rows in the tile grid at the given level. Each level should have twice the number of rows of the previous one.

Returns the width, in pixels, of the tiles at the specified detail level. All tiles are assumed to have the same resolution.

Signals that the underlying data for the tiled images has changed. If this model is added to a map using a RasterTileSetLayer, calling this method will thus trigger a refresh of the visualization.
