Both open source and proprietary geographic information systems currently offer limited out-of-the-box support for complex GML. For a more in depth discussion of GML support in GIS software, visit the CanIUse INSPIRE github repository. Harmonized INSPIRE data is complex GML and this tutorial aims to demonstrate how hale»connect WMS services can be viewed in ArcGIS Online.
The Esri WFS implementation in ArcGIS Online only supports basic OGC WFS at the simple features level.
This tutorial uses:
In order to view your hale»connect WMS in ArcGIS Online, you will need a URL link to the capabilities document of your service. You can directly access the capabilities documents for WMS 1.1.1 and 1.3.0 from the View Services section of your dataset. To copy any URL to the clipboard, click the icon to the right of the URL.
Login to ArcGIS Online and navigate to My Map. Click on the Add tab at the top left of the application.
From the Layer menu, select Add layer from the Web. In the Add layer from the Web dialog, select WMS-OGC-Web-Service as service type in the dropdown menu and enter the URL of your WMS capabilities document. Click Add layer.
Your WMS layer should appear in the layers panel on the left. Left click on the three dots which appear under the WMS name to view the options menu. The menu includes a range of options, such as zoom, transparency, rename and the option to further refine your OGC WMS request parameters.
Next, click on the black arrow next to the WMS name. Your WMS layer should appear. Left click on the three dots which appear under the layer name to activate pop-ups.
Once you activate pop-ups for your layer, the GetFeatureInfo response will display in the pop-up dialog for any feature that you click. If you click on an area with overlapping features, results for each feature will be listed. hale»connect services provide the unique ability to explore complex GML through the hale»connect FeatureExplorer. In the pop-up dialog in ArcGIS Online, click on the Details anzeigen button for the feature you are interested in.
The hale»connect FeatureExplorer will open in a new tab in your browser. The FeatureExplorer enables you to navigate through any level of nested, complex GML to further investigate the linked resources, linked features, codelists or attributes that you are interested in.
