Installing the WMTS multidimensional extension

The WMS multidimensional extension is listed among the other extension downloads on the GeoServer download page.

The installation process is similar to other GeoServer extensions:

  1. Download the geoserver-2.26.x-wmts-multi-dimensional-plugin.zip

    Verify that the version number in the filename corresponds to the version of GeoServer you are running (for example 2.26-SNAPSHOT above).

  2. Extract the contents of the archive into the WEB-INF/lib directory in GeoServer. Make sure you do not create any sub-directories during the extraction process.

  3. Restart GeoServer.

If installation was successful, the WTMS capabilities document will contain the extra requests provided by the module, e.g.:

<ows:Operation name="DescribeDomains">
  <ows:DCP>
    <ows:HTTP>
      <ows:Get xlink:href="http://localhost:8080/geoserver/gwc/service/wmts?">
        <ows:Constraint name="GetEncoding">
          <ows:AllowedValues>
            <ows:Value>KVP</ows:Value>
          </ows:AllowedValues>
        </ows:Constraint>
      </ows:Get>
    </ows:HTTP>
  </ows:DCP>
</ows:Operation>
<ows:Operation name="GetDomainValues">
  <ows:DCP>
    <ows:HTTP>
      <ows:Get xlink:href="http://localhost:8080/geoserver/gwc/service/wmts?">
        <ows:Constraint name="GetEncoding">
          <ows:AllowedValues>
            <ows:Value>KVP</ows:Value>
          </ows:AllowedValues>
        </ows:Constraint>
      </ows:Get>
    </ows:HTTP>
  </ows:DCP>
</ows:Operation>

A simple DescribeDomains request can be used to test if the module was correctly installed, the request can be made against any layer known by the WMTS service. For example, using the demo layer tiger:poly_landmarks shipped with GeoServer:

http://localhost:8080/geoserver/gwc/service/wmts?REQUEST=DescribeDomains&Version=1.0.0&Layer=tiger:poly_landmarks&TileMatrixSet=EPSG:4326

The result should be similar to the following, this layer doesn’t have any domains:

<?xml version="1.0" encoding="UTF-8"?><Domains xmlns="http://demo.geo-solutions.it/share/wmts-multidim/wmts_multi_dimensional.xsd" xmlns:ows="http://www.opengis.net/ows/1.1">
  <SpaceDomain>
    <BoundingBox CRS="EPSG:4326" minx="0.0" miny="0.0" maxx="-1.0" maxy="-1.0"/>
  </SpaceDomain>
</Domains>

If the module is not correctly installed the result will be an exception saying that this operation is not available:

<ExceptionReport version="1.1.0" xmlns="http://www.opengis.net/ows/1.1"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

  <Exception exceptionCode="OperationNotSupported" locator="request">
    <ExceptionText>describedomains is not implemented</ExceptionText>
  </Exception>
</ExceptionReport>
