    If you are adding a HTTPs WMS URL which uses a SSL certificate that is not trusted by SSA server, you need to install the root certificate or any intermediate certificates for corresponding certificate authority in SSA trust store. For more information on how to install 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 Authentication Type drop-down list. It has following options:
    OptionDescription

  13. Select from available check box options:
    OptionDescription

    Note: The Get Feature Info check box is disabled and unchecked 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 user will add WMS either secured or non–secured, SSA will check whether these supports CORS or not and“CORS Enabled” option will be checked/unchecked 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 which 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 image format from Choose Get Map Format drop-down list. The supported Get Map format is image/png, image/gif, image/jpeg, or image/jpg.
  16. Click Save button to save the WMS configuration.
  17. Click Back button to go to previous screen or click Cancel to exit Add WMS dialog box.

The WMS configuration is now added to the list.
