A TiledImageSource backed by a single WMTS layer. Note: this is a convenient class that simplifies the usage of TiledImageSource.

Currently, it is not possible to directly create a WmtsSource from its constructor. Use the fromCapabilities static method to build a source from a WMTS capabilities document.

WmtsSource.fromCapabilities('http://example.com/wmts?SERVICE=WMTS&REQUEST=GetCapabilities', {
layer: 'MyLayerName',
})
.then(wmtsSource => {
// Do something with the source.
});

version: number

Accessors

  • get colorSpace(): ColorSpace
  • Gets the color space of the textures generated by this source.

    Returns ColorSpace

Methods

  • Returns an adjusted extent, width and height so that request pixels are aligned with source pixels, and requests do not oversample the source.

    Parameters

    • requestExtent: Extent

      The request extent.

    • requestWidth: number

      The width, in pixels, of the request extent.

    • requestHeight: number

      The height, in pixels, of the request extent.

    • margin: number = 0

      The margin, in pixels, around the initial extent.

    Returns {
        extent: Extent;
        height: number;
        width: number;
    }

    The adjusted parameters.

    • extent: Extent
    • height: number
    • width: number
  • Gets whether this source contains the specified extent. If a custom contains function is provided, it will be used. Otherwise, intersects is used.

    This method is mainly used to discard non-relevant requests (i.e don't process regions that are not relevant to this source).

    Parameters

    • extent: Extent

      The extent to test.

    Returns boolean

  • Initializes the source.

    Parameters

    • options: {
          targetProjection: string;
      }

      Options.

      • targetProjection: string

        The target projection. Only useful for sources that are able to reproject their data on the fly (typically vector sources).

    Returns Promise<void>

    A promise that resolves when the source is initialized.

  • Test the intersection between the specified extent and this source's extent. This method may be overriden to perform special logic.

    Parameters

    • extent: Extent

      The extent to test.

    Returns boolean

    true if the extent and this source extent intersects, false otherwise.

  • Constructs a WmtsSource from a WMTS capabilities document.

    Parameters

    Returns Promise<WmtsSource>

    A promise that resolve with the created WmtsSource.

    const url = 'http://example.com/wmts?SERVICE=WMTS&VERSION=1.0.0&REQUEST=GetCapabilities';

    // Creates the source with layer 'MyLayer' in the 'PM' tile matrix set.
    const wmtsSource = await WmtsSource.fromCapabilities(url, {
    layer: 'MyLayer',
    matrixSet: 'PM',
    imageFormat: 'image/png',
    });
