Adding WMS

To add a WMS configuration:

  1. Open the WMS tab.
  2. Click the Create New button to create a new web mapping service.
    The Add WMS dialog box opens.
  3. In the Add\Edit WMS dialog box, enter the URL in the WMS URL text box.
    If you are adding an HTTPS WMS URL that uses an SSL certificate that is not trusted by the SSA server, you need to instal the root certificate or any intermediate certificates for the corresponding certificate authority in the SSA trust store. For more information on how to instal an SSL certificate for web map service, refer to Installing SSL Certificate for WMS.
    Note: The WMS URL may or may not require authentication.
  4. Select the authentication from the Authentication Type drop-down list. It has the following options:
    OptionDescription
    No Authentication The WMS is not secured and does not require a login.
    Basic Authentication The WMS is secured and a username and password are required to log in and access the WMS.
    Query Parameters Inline The WMS is not secured, but a username and password are required as part of the WMS URL parameters. Enter query parameter names and values as below:
    • Username Query parameter
    Enter the parameter name for the username. For example - login, userid, login id etc.
    • Username
    Enter the username
    • Password Query Parameter
    Enter parameter name for the password. For example - password
    • Password
    Enter the password
  5. Click the Open button to read the WMS capabilities. The dialog will move to step 2 and display the available layers. Click Cancel to close the Add\Edit WMS dialog box.
  6. In the Add\Edit WMS dialog box, the WMS URL is displayed under Viewing WMS.
  7. Enter the name for this configuration in Enter name for this WMS text box. This name appears under the Name list on the WMS page.
    Note: You cannot keep this text box empty and the WMS name cannot be the same as the existing WMS configuration.
  8. Select layers from the Available Layers list.
    Note: You may select more than one layer by pressing the Ctrl button.
  9. Click the Add button to move selected layers to the Selected Layers box.
  10. Click the Remove button to remove one or more layers from the Selected Layers box.
  11. Select a layer in the Selected Layers list and click the Up and Down arrow buttons to reorder its position in the list.
  12. Select a style from the Choose Style drop-down list for each layer.
  13. Select from the available tick box options:
    OptionDescription
    Get feature info Select to get feature information.
    Note: The Get Feature Info tick box is disabled and unticked if it does not support the getFeatureInfo capability.
    Get Legend Graphic Select to get legend graphics.
    CORS Enabled Select to check if the tile server supports CORS (Cross-origin Resource Sharing).
    Note: When a user adds either a secured or non-secured WMS, SSA will check whether this supports CORS or not and the “CORS Enabled” option will be ticked/unticked by default.
  14. Choose projections from the Choose Projection drop-down list.
    Note: Some projections supported by WMS are “geographic” rather than “projected” projections. Geographic projections use degrees as units and one example that is commonly used is epsg:4326. The Mapping Service used by Spectrum Spatial Analyst does not render maps in a form that aligns with geographic projections. The misalignment is more pronounced as you move further north or south from the equator. Please be aware of this limitation when choosing a geographic projection, as no warning message is shown when adding maps from the Mapping Service.
  15. Choose the image format from the Choose Get Map Format drop-down list. The supported Get Map format is image/png, image/gif, image/jpeg or image/jpg.
  16. Click the Save button to save the WMS configuration.
  17. Click the Back button to go to the previous screen or click Cancel to exit the Add WMS dialog box.

The WMS configuration is now added to the list.
