WMS Services

Lizard provides a Web Map Service (WMS) that you can use to visualise rasters and 3Di scenarios stored in Lizard Raster Server as tiled images. The Lizard WMS Service follows the OGC WMS guidelines.

Rasters

To visualise and request the GetCapabilities of a specific raster you can use the following URL:

https://{yourportal}.lizard.net/wms/raster_{UUID of raster}/?request=GetCapabilities

for example: https://demo.lizard.net/wms/raster_eae92c48-cd68-4820-9d82-f86f763b4186/?request=GetCapabilities

You can easily find the UUID of the raster in the Lizard Catalogue or API. The Lizard Catalogue also provides the Lizard WMS GetCapabilities link for each raster. With the GetCapabilities query parameter you retrieve the metadata of the service, including supported operations, parameters and a list of available layers.

3Di Scenarios

To visualise and request the GetCapabilities of a 3Di scenario (list of rasters) you can use the following URL:

https://{yourportal}.lizard.net/wms/scenario_{UUID of scenario}/?request=getcapabilities

For example: https://demo.lizard.net/wms/scenario_c30ef7f2-c871-4d70-a087-8f078f9ebafd/?request=GetCapabilities

You can look up the UUID of the scenario using the Scenarios endpoint in the Lizard API. All available filters are listed on the endpoints’ page. E.g. you can look up a scenario and it’s uuid by filtering on your own username. With the GetCapabilities query parameter you retrieve the metadata of the service, including supported operations, parameters and a list of available layers.

Layer collections

To visualise and request the GetCapabilities of layer collections (list of rasters, previously called ‘datasets’) you can use the following URL:

https://{yourportal}.lizard.net/wms/{slug of layer collection}?request=GetCapabilities

For example: https://demo.lizard.net/wms/basiskaarten/?request=GetCapabilities

You can search for layer collections in the Lizard Catalogue by using the Layer collection filter in the left panel. You will find the Lizard WMS GetCapabilities URL of the layer collection in the metadata panel of a specific layer.

Authorisation

The Lizard WMS Service follows the authorisation system mentioned under Authorisation. If layers are private you need privileges in the organisation that owns the data.

Use a Personal API Key to authenticate with the Lizard WMS Service, as described in API Authentication.

In QGIS the authentication is filled in as follows:

  • username = __key__

  • password = Personal API Key

How to load WMS in GIS

You can connect directly to Lizard in a GIS application like QGIS.

  • 1

Open QGIS and load a new WMS connection.

  • 2

Give the connection a name and copy the wms link from ‘https’ to ‘GetCapabilities’, e.g. “https://maps1.klimaatatlas.net/geoserver/twn_klimaatatlas/wms/?request=GetCapabilities”.

  • 3

If the wms layer is not public, you have to enter your Credentials. in the Authentication - Basic tab.

  • 4

Click OK and double click on the connection. If multiple layers appear, double click on the one you are interested in.

The styling will automatically be taken from Lizard. If the layer is temporal, you can also navigate through time.
