OGC specifications

ArcGIS Enterprise supports the following OGC specifications in the ways described:

Add OGC WFS layers

When you add OGC WFS layers to a map, you must choose one sublayer at a time. To add more layers from the same WFS layer, repeat the steps to add the layer and choose a different sublayer each time. You can also specify advanced configuration options when you add a WFS layer to a map. You can change the maximum feature limit or choose to flip x,y coordinates. If the WFS layer contains complex features, you must also select the type of features to display: points, lines, or polygons.

When you add a WFS layer to the map, your basemap must be compatible with the coordinate system of the WFS layer.

Add OGC WMS layers

When you add an OGC WMS layer to a map, you can choose to add all the layers in the service or select the layers you want to add. If you add all the layers in the service, all the layers are added to the map, but only the first layer is displayed. To turn on the other layers, click the Contents button, click the OGC WMS layer name, and check the boxes next to the layers you want to appear in the map. You can also control which layers in your OGC WMS service appear on the map by choosing the layers you want when adding the OGC WMS as an item or updating the item.

By default, when you add an OGC WMS layer as a basemap, the first 10 layers in the service are added and all 10 layers appear visible. You can select different layers in the WMS service to add to the basemap when you add the WMS to the map or if you add the WMS as an operational layer and move it to the basemap.

You can also add WMS layers to Scene Viewer. After adding a WMS layer, you can view the legend and configure pop-ups, save the layer in a scene, and share it.

Add OGC WMTS layers

Each layer in an OGC WMTS service contains a set of cached images and can have a different tiling scheme than the other available layers in the WMTS service. Only add the layers that your map audience needs to see because a lot of cache image tiles can clutter the map and it may take a long time to draw, especially in web browsers. To help maximize the performance of your map, you select a specific layer to add from your WMTS service. You can add more than one layer, but you need to go back through the process of adding the WMTS to your map.

When adding WMTS as an item, you must select a specific layer and must also select the coordinate system for the layer, if the layer supports multiple coordinate systems. To add multiple layers or additional coordinate systems, you must author individual items for each layer or coordinate system.

You can also add WMTS layers to Scene Viewer.

Use compatible basemaps with WMTS, WMS, and WFS layers

For maps to display correctly, the coordinate systems of the layers and basemaps must be compatible. In addition, the tiling scheme of a WMTS layer must match the tiling scheme of the basemap. Map Viewer Classic attempts to draw your layer with the basemap you select. If Map Viewer Classic can't draw your layer on the basemap (because the coordinate system or tiling scheme doesn't match), and the OGC WMS or WMTS layer is the first layer you've added to a map, Map Viewer Classic attempts to use a different basemap.

For example, if your layer is in GCS WGS84, Map Viewer Classic uses the GCS WGS84 World Imagery basemap. Your portal administrator may have changed the default basemaps and may have included some that support your layer's coordinate system. If a basemap in the gallery is not compatible, Map Viewer Classic uses your layer as the basemap. If you add an OGC WMS or WMTS layer to an existing map or it is not compatible with any basemaps in your gallery, Map Viewer Classic will not add it to your map; instead, you will see an error message stating that your layer is not compatible with the basemap's coordinate system.

For OGC WFS layers, the coordinate system of the basemap must be supported by the WFS service or the layer may not be drawn successfully. Map Viewer Classic will not switch to use a compatible basemap. If the basemap is not compatible with the WFS layer, Map Viewer Classic will display a message to that effect.

Secure OGC services

OGC WFS, WMS, and WMTS services secured with web-tier authentication, such as Integrated Windows Authentication (IWA), a public key infrastructure (PKI), Basic, or Digest access authentication, are supported. OGC WFS, WMS, and WMTS services secured with token-based authentication are not supported. Configure support for OGC services secured with web-tier authentication by adding the server hosting the services to your organization’s list of trusted servers. The server on which the OGC services are running must support Cross-Origin Resource Sharing (CORS); otherwise, the OGC layers will not function as expected in your portal. Additionally, you must configure CORS to allow the specific domains that will communicate with the server, such as your ArcGIS Enterprise portal domain.

Once you've added the server to the list of trusted servers, you can add your OGC services to the map or as an item. If authentication is necessary, users adding or viewing secured OGC layers will be prompted to enter their credentials.

Limitations

The following are the current limitations of using OGC layers in ArcGIS Enterprise:

• OGC WFS, WMS, and WMTS layers are supported in Map Viewer Classic.
• Maps that contain OGC WFS, WMS, and WMTS layers can be added to Map Viewer for display purposes only.
• You cannot edit features or add token-based secure OGC layers.
• If the portal website is installed on the same network as an OGC WMS layer, the OGC WMS layer will be accessible in Map Viewer Classic and the website (WMS only); otherwise, internal OGC WMS layers are not supported.
• Your WFS, WMS, and WMTS layer and basemap must use the same coordinate system, for example, Web Mercator (the coordinate system of the default basemaps in the basemap gallery). Your administrator may have changed the default basemaps. Check with your administrator if you have issues using basemaps with your OGC layer.
• OGC WMS group layers are not supported.
• Refresh on OGC WMS layers only works if the WMS service honors standard HTTPS caching rules.
• If the option to enable pop-ups is not available for the WMS layer, you may need to add the layer to the map again or re-create the WMS item. Some WMS layers do not support pop-ups.
• When printing OGC WMS or WMTS layers, custom parameters are not supported.
