An internet connection is required to connect to ArcGIS Online.
Using ArcGIS Online Import
To access the User Portal and import raster data from ArcGIS Online, go to the Advanced Import dialog box, choose the ArcGIS Online format and click Browse.
Enter your ArcGIS Online credentials and click Login.
To log in as another user, enter different ArcGIS Online credentials. To log out completely of ArcGIS Online, you must quit or restart Adobe Photoshop.
In the User Portal dialog box, all of the account's raster datasets are listed. Both Map Image Layer and Tile Layer types are supported.
Optionally, use the Filter to quickly search for layers based on title or tag.
Select a Map Image Layer or Tile Layer and click Open or double-click a layer to begin the import process. Depending on the type of layer, the import options may differ slightly.
Import From Map Image Layer or Tile Layer
When opening Map Image Layers or Tile Layers, the Import From Image Layer dialog box appears and allows you to choose a specific image area to import. The allowable maximum image size to import is determined by the maximum width set by the layer.
Click the Select Area button to specify a smaller area to import. Drawing a marquee box in the map preview is the quickest and simplest method to select an area. In the preview image, click and drag to draw to select an area—the image immediately crops to the select area. The crop area can be only as large as the extent of the image and only one crop area can be defined at a time. Click Undo to undo the previous selection. Click Reset to Original Extents to return to the original extents of the layer specified by the service.
To learn more about how to select an area by extents, by position, by MAP view, by file vector extents, or by coordinate system envelope, see Select Area.
Using ArcGIS Web Service
To import raster data from an ArcGIS web service, go to the Advanced Import dialog box or File > Automate, choose the ArcGIS Web Service format and click Browse. In the Connect to ArcGIS Web Service dialog box, enter an ArcGIS web service URL. When an ArcGIS web service URL is entered, Geographic Imager will attempt to validate the URL and identify the type of layer to import. Previously imported services are saved in the Service URL drop-down.
You can find service URLs directly from ArcGIS Online. Go to My Content, click the drop-down menu arrow of a layer in the listing and choose View item details. On the right-side column, the URL is displayed and can be copied.
Accessing an ArcGIS web service differs slightly because it can initially be accessed by anyone with the URL. However, depending on web service permissions, it may be public where anyone can access the service or maybe private, and only authenticated users may access the service. Depending on the service permissions, you may be required to sign in with the appropriate account credentials to gain access. The Status displays whether you are logged in, not logged in, or if the service is valid, but the server and login status is unknown (this generally happens the first time accessing a service). Below is a summary of Status messages and their description.
Unknown server; login status unknown.
Although the service URL is valid, it may be of unknown origin. You may also need to sign in to ArcGIS with your account credentials to access the data.
Logged in as <user>.
You're logged into the account displayed.
Not logged in.
You're currently not logged in.
Login not required.
You're not required to log in.
Because some ArcGIS web service URLs can be public, there is no sign-in option.
Depending on the type of ArcGIS web service, the import options may differ slightly but are similar to importing an ArcGIS Online layer (see above).
