Minimum raster analysis system

If an organization has resources and limited conflicts in terms of competing raster analysis processing and image service distribution resources, the raster analysis server and image hosting server functionality can be combined and hosted on one server. In this implementation, the raster analysis and image processing operations are executed on an ArcGIS Image Server site configured as the raster analysis server, while the results are managed and published through the same ArcGIS Image Server site. The ArcGIS Image Server site does the work of processing analytics requests, storing the results, and returning results to members in the Portal for ArcGIS site.

A diagram of the minimum raster analysis system is shown below.

The raster analysis and output image hosting server requires an ArcGIS Image Server license.

The instructions to set up and configure the minimum raster analysis system are outlined below.

Setup a minimum raster analysis system

The following instructions may require changes to the way you've deployed ArcGIS in your organization; review them carefully before proceeding. To configure the portal to perform image hosting services, follow the steps below.

1. Ensure that you have configured a base ArcGIS Enterprise deployment.
2. Set up an ArcGIS Image Server.
   1. Install an additional ArcGIS Server site.
   2. Authorize ArcGIS GIS Serverwith an ArcGIS Image Server license to function as the ArcGIS Image Server site.
3. Begin configuring ArcGIS Image Server by signing in to ArcGIS Server Manager and browse to Site > Data Stores.
4. Register the raster data store with ArcGIS Image Server.

   Raster analysis services store processed rasters in a data store, referred to as raster store. This can be either of the following:

   • File share type of raster datastore—In this configuration, both the analysis output and the mosaic dataset will be stored at the file share raster store.
   • Cloud store with file share type of raster datastore—In this configuration, the analysis output will be stored at the cloud raster store and the mosaic dataset will be stored at the file share raster store.
   • Cloud store with enterprise geodatabase types of raster store—In this configuration, the analysis output will be stored at cloud raster store and the mosaic dataset will be stored at the enterprise geodatabase raster store.

     Tip:

     This type of configuration is recommended for better scalability for hosted imagery layers.

   Note:

   If an image hosting server is specified in your raster analytics deployment, and you want to publish an image service, the same raster store name with same path or connection details need to be registered in both your image hosting server and raster analysis server sites.

   If the input data is accessed from your data stores, those data stores should be registered in both the raster analysis and image hosting servers.

   1. To use a folder, use ArcGIS Server Manager, register a UNC share in the data store, and give it a name.

      Note:

      If there are multiple instances of _raster_store defined, for example, raster_store1, raster_store2, and so on, raster analysis will randomly pick one for a task request.

   2. To use a cloud store, provide the access key, secret access key, region, and bucket name. The cloud store settings include subfolder support.

      

      Note:

      To use a cloud store as a raster store, the ArcGIS Server account user must have read, write, and delete permission on the cloud bucket to properly manage the data.

5. Ensure that you have increased the SOC maximum heap size to 128 MB for ArcGIS Image Server.

Note:

To deploy your raster analysis server in the cloud with Amazon Web Services (AWS), see ArcGIS Enterprise Cloud Builder CLI for AWS. To deploy your raster analysis server in the cloud with Microsoft Azure, see Deploy ArcGIS Enterprise on Microsoft Azure.

Federate and configure the server for raster analysis and image hosting

Next, you will designate the ArcGIS Image Server site to perform raster analysis and host your imagery layers.

1. Sign in to the portal as a member with administrative privileges. The URL is in the format https://webadaptorhost.domain.com/<webadaptorname>/home.
2. Browse to Organization > Settings > Servers.
3. Federate your ArcGIS Server site.
4. On the Servers page, locate the ArcGIS Image Server site that you federated with the portal.
5. Open the Configure server role dialog by doing one of the following:
   1. Next to Server role, click the current server role or Configure server role if no role is currently assigned.
   2. Click the More options button and select Configure server role.
6. On the Configure server role dialog box, enable Raster Analysis Server.
7. Click Save.
Once configured, the federated server will include Raster Analysis Server in its server role description.
8. Assign the minimum permissions needed to perform raster analysis.
9. Ensure that you have increased the SOC maximum heap size to 128 MB for ArcGIS Image Server.

Assign permissions

Next, you will assign the minimum permissions needed to perform raster analysis.

1. Browse to the Organization > Settings > Member roles page.
2. Next to the role that will be performing raster analysis, click the More options button and select Edit.
3. In the Edit role window, expand Content.
   1. Enable the options for Create, update, and delete and Publish hosted dynamic imagery layers.
4. Expand Content and Analysis.
   1. Enable Standard Feature Analysis.
   2. Enable Imagery Analysis.
