California Aerial Imagery Program Install Instructions
Background:
A REST API (Representational State Transfer API) enables communication between a client and a server over HTTP. It exchanges data typically in JSON format using standard web protocols.
A REST endpoint in ArcGIS refers to a URL that provides access to specific services or resources hosted on an ArcGIS server or platform. These endpoints allow developers to interact programmatically with ArcGIS services, enabling tasks such as querying data, performing spatial analysis, or managing content.
The top image shows the same Feature layer from the previous pair. The bottom image is a different kind of Feature layer, called a hosted feature layer. Both types of feature layers support editing, but the underlying technology that enables each type is different.
The data for a hosted feature layer must be copied into ArcGIS. The data for a non-hosted feature layer can be in a user-managed data store, like an enterprise geodatabase. Hosted feature layers use less server memory than non-hosted feature layers. One advantage of a non-hosted feature layer is that you can use advanced database features like versioning and topology. You also have more control over configuring non-hosted feature layers, but that control comes with more responsibility for configuring them correctly.
Hosted feature layers are available in both ArcGIS Online and ArcGIS Enterprise. Non-hosted feature layers are available only in ArcGIS Enterprise.
The relationship between services and layer items has two important implications. The first is that you can have multiple different layer items that all reference the same service. The second is that different types of layers have different types of services as their source: feature services for Feature layers (whether hosted or not) and map services for Map Image Layers.
How can I provide access to others I work with?
CDT will set up a single admin account per administrative unit. The primary administrator can then create additional accounts with the ability to access the Hexagon WMS/WMTS services directly if they choose. However, we typically recommend, and will provide instructions on, adding an item within your ArcGIS Online organization that shares the services internally, passing requests through to Hexagon. This approach makes the service widely available to your organization without administering separate accounts.
Directions:
Adding Aerial Imagery to ArcGIS Pro
- Navigate to Insert > Connections > New WMTS Server.
- The Add WMTS Server Connection window will open.
-
In the URL field, add the URL: https://services.hxgncontent.com/streaming/wmts
Under the Optional section, fill in your username and password. Select the “Save Username"

The connection to the streaming service has been made and is shown in the Catalog window under the Servers folder. Double-click on “Servers” to see the connection to the HxGN Content Program
- Double-click on “Hexagon Content Program – WMTS,” then double-click on “HxGN Content Program” to view your subscribed data layers
- Right-click on the layer you wish to add, click on “Add to New,” and then click on “Map.”
Note: You will need to sign in each time you open a map with the service.
Adding Aerial Imagery to AGOL
1. Open your map in Map Viewer.
2. Click on “Add” and select “Add layer from URL.”
In the URL field, add the URL: https://services.hxgncontent.com/streaming/wmts
Click on “Custom Parameters” and click on “Add Parameters.”
-
Enter the parameter's password and fill in the value parameter with your username. Click on “Add.”
