FAQ

General

Yes, ArcGIS Maps SDK for Unity is a fully supported SDK to use with ArcGIS services, image tile packages, and scene layer packages.

Windows and macOS. The Apple M1 processor is not supported. Go to System requirements to see the specific requirements.

Windows, macOS, Android, iOS, and XR platforms. Go to Deployment to see the specific deployment settings.

ArcGIS services

The ArcGIS Maps SDK for Unity has built in functionality to access the following ArcGIS services:

  • Basemap layer service
  • Elevation service (limited to single elevation source)
  • Image tile service
  • Scene service (limited to 3D object scene layers and integrated mesh scene layers)

You can also access other services such as the routing service by using ArcGIS REST APIs. To see examples of how to use ArcGIS REST API, go to Feature layer query.

ArcGIS location services

Yes, you must provide an API key or implement OAuth 2.0 with ArcGIS Identity or Application credentials to access ArcGIS location services.

ArcGIS Enterprise services

For services that are private, yes, you need to provide authentication to access ArcGIS Enterprise services. You typically implement OAuth 2.0 with ArcGIS Identity or Application credentials to do so. Public services do not require authentication.

To learn more about the different types of authentication, go to Security and authentication in the Mapping APIs and location services guide.

No. The raster image tile services are no longer maintained or recommended for use by Esri.

To learn more about ArcGIS location services and their capabilities, go to the Mapping APIs and location services guide.

To learn more about ArcGIS Enterprise services and their capabilities, go to the REST API documentation.

Service usage and billing

You need either an ArcGIS Developer account or ArcGIS Online account. This will give you the ability to access the developer dashboard, create API keys, set up OAuth 2.0, and manage your data.

To learn more about account types, go to Accounts in the Mapping APIs and location services guide.

The cost to access ArcGIS location services depends on the type of ArcGIS account you have and the services you use.

  1. If you have an ArcGIS Developer account, you are billed in US dollars. To determine the cost of accessing different services, go to Pricing. A free tier of access is available for some services.

  2. If you have an ArcGIS Online account, you are billed in credits. To determine the cost of accessing different services, go to Understanding credits.

If you have ArcGIS Enterprise, there is no cost for accessing your own ArcGIS services.

To learn about accounts, content and data, and basemap layer attribution, go to Deployment in the Mapping APIs and location services guide.

Esri's Terms of use is located in the Mapping APIs and location services guide.

Troubleshooting

Before troubleshooting layer loading issues, make sure that you have added an ArcGIS View State Logging Component. This component notifies you of any updates to the status of layers, elevation sources, and the view. These events tell you whether your data is active, if it fails to load, or any usage warnings that come with using a specific dataset to help you determine when there is a problem with your GIS data. If the view state log doesn't give you the exact information you need, you can follow the checklist below:

  1. Check that your camera is looking at the correct area. If you are using the Map Creator UI, you can use zoom to to go to your data extent.

  2. Check that you use supported format for basemaps and data layers and elevation layers.

  3. If you are adding 3D object scene layers or Integrated mesh scene layers, your file needs to be version 1.7+. You can check this by opening the JSON file that is associated with the service. For the online services, if the JSON content is not displayed by accessing the service URL, try to add ?f=json at the end of the service URL to access the content. For local data, you can extract the file as a zip archive, and open the .json file.

  4. Check if your spatial reference is supported by the map type. Global scenes support all the geographic coordinate systems. For a projected coordinate system, only Web Mercator (Auxiliary Sphere) (WKID: 3857) is supported. Local scenes support all projected coordinate systems. For the geographic coordinate system, WGS 84 (WKID: 4326) and China Geodetic Coordinate System 2000 (WKID: 4490) are supported.

  5. Your data's spatial reference may differ from your ArcGIS Map's spatial reference which prevents your data from loading. This is because ArcGIS Maps SDK for Unity uses the first layer added (oftentimes the basemap) to determine the spatial reference for the ArcGIS Map. In this case, reset the spatial reference of ArcGIS Map by removing the existing basemap/first layer and adding the new layer as the first layer. Make sure to save the level and reload for ArcGIS Map to be updated for the editor mode.

  6. When you use a private online service in your app, you need to set up OAuth 2.0 with ArcGIS Identity or Application credentials. Private online services are loaded only after successful authentication.

  7. If all of the above are correct and your data is loaded in other products like ArcGIS Pro, your data might be corrupted or saved in an old format. Try to export the file package again or republish the service.

The Map Creator UI pushes values to components. However, when you change the values in the component for the settings in the opened Map Creator UI panel, not all changes can be pushed from the component to the Map Creator UI. Click on another tab of the Map Creator UI to pull the new values from the component.

Performance is related to many factors. In the Unity Manual you can find performance and optimization tips.

Disabling the editor mode can increase performance while you are developing an app. You can disable the feature via C# API or from the Enable Editor Mode checkbox if you have the ArcGIS Map component in your scene.

When you use a high specs machine to develop or run your app, ArcGIS Maps SDK for Unity may not be using all the power that the machine has. You can implement the IMemorySystemHandler interface and set an instance of the implementation to ArcGISMapComponent. You can also adjust memory allowance manually by specifying system memory and video memory values in GameEngine.View.ArcGISView with SetMemoryQuotas. See Unity's documentation: Memory in Unity for more information about working with memory in Unity.
