Adding Layers

Add OGC-compliant layers from Web Services to view imagery and vector data in the viewport.

The Layers panel with several custom layers added.

1. Select Layers. The Layers panel opens.

2. Select Add Layer. The Add New Layer panel opens.

3. From the GIS Web Service Type drop-down, select the type of endpoint you want to add. The following endpoints are available:

   • Image Service Endpoint URL

   • Map Service (ESRI) Endpoint URL

   • WFS Endpoint URL

   • WMS Endpoint URL

   • WMTS Endpoint URL

   • GeoJSON Upload

   At this time, Hub supports public endpoints.

4. Do one of the following, depending on the type of layer you are uploading.

   Upload a GeoJSON Layer

   • To select the file you want to import, do one of the following:

     • Drag and drop a GeoJSON file from your computer into the dotted area.

     • Select Select from Computer. In the dialog that opens, locate the GeoJSON file you want to import, then select Open.

     The file uploads.

   Upload Another Type of Layer

   1. In the Service Web Address (URL) field, enter the URL for your layer.

   2. Select List Layers. When a successful connection occurs, the Available Third-Party Layers drop-down list displays.

   3. From the Available Third-Party Layers drop-down, select the third-party layer(s) you want to add to your custom layer.

      If you select multiple third-party layers at the same time, they are added as a single custom layer in Hub. If you want to manage each layer separately (e.g., control each layer's opacity separately, delete layers individually), you should add them one at a time.

   4. In the Name field, enter a name for the layer.

   5. (Optional) In the Description field, enter a description for the layer.

5. Select Add Layer. The custom layer is added to the Layers panel. Select the layer to turn it on. See Viewing Layers.

   

   The Add New Layers panel with a third-party layer added.

   At this time, Hub only supports layers with the EPSG:3857 projection. If you select a service that contains layers with an incompatible projection, data from that layer may not display, or may display incorrectly.

   When adding a supplemental layer, Hub attempts to securely transmit information to and from the third-party server using Cross-Origin Resource Sharing (CORS). CORS is a mechanism that allows secure, cross-site data transfers. If the third-party server does not allow access from Vantor domains (or if CORS fails for any other reason), the layer cannot be viewed from within Hub.
