Editing WMS

To edit an existing WMS configuration:

  1. Open the WMS tab.
  2. In the Name list, select the WMS that you want to edit.
  3. Click the Edit button on the right-hand side of the screen.
    The Add\Edit WMS dialog box opens.
  4. In the Add\Edit WMS dialog box, the WMS URL is displayed under Viewing WMS.
    Note: The layers that were previously selected will be shown in the ‘Selected Layers’ container on the right-hand side.

    The Choose Projection drop-down will display the previously selected projection.

  5. Select layers from the Available Layers list.
    Note: You may select more than one layer by pressing the Ctrl button.
  6. Click the Add button to move selected layers to the Selected Layers box.
  7. Click the Remove button to remove one or more layers from the Selected Layers box.
  8. Select a layer in the Selected Layers list and click the Up and Down arrow buttons to reorder its position in the list.
  9. Change style from the Choose Style drop-down list for each layer.
  10. 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.
  11. 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.
  12. 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.
  13. Click the Save button to save the updated WMS configuration.
  14. Click Cancel to exit the Edit WMS dialog box.

The WMS configuration is now updated.
