Several Digimap Collections provide a Web Map Service (WMS). You can add these WMS to Roam in a different collection. For example, add the Ordnance Survey WMS to Historic to view current and historical maps in combination.
Open the Roam where you want to view the WMS.
In Roam, select Overlays from the sidebar.
Select the WMS tab (note this step is not required in every Roam).
Now select Manually Add WMS Feed.
Paste your WMS link into the first line of the box, titled ‘3rd Party WMS URL’.
NOTE: if your URL has HTTP at the beginning, please change this to HTTPS.
Select Get Layers.
You should now be able to see a list of layers available from your WMS.
Select the eye icon to turn a layer on or off.
Use the arrows to change the order of display of any layer.
Select the pencil icon to edit the name of any layer.
Select Add Layers to Map.
You should receive a confirmation message to say your feed has been added.
Your WMS should be visible in the Overlays area and your map display changed.
You can switch WMS, or layers of the WMS, on or off in the Overlays menu. Just switch the button next to each WMS on or off.
There is an opacity slider under each WMS to let you adjust your map display. Just move it left or right to see more or less of your WMS map data.
