Identify Operations on Raster Layers

Geocortex Essentials and the HTML5 Viewer support identify operations on ArcGIS Server raster layers. Identify operations are enabled by default for all layer types. If you do not want users to be able to identify on a raster layer, disallow identify operations on the layer.

By default, users can identify by point only. If the user performs some other type of identify, such as a polygon identify, no results are returned from the raster layer. You can configure an HTML5 viewer to return raster layer results for line-based and polygon-based identify operations. The viewer's Identify Module has a property called restrictRasterIdentifyToPoint that controls this.

ArcGIS Server raster layers have Feature Label, Feature Description, and Feature Long Description settings so you can configure the content and appearance of identify results. For information about these settings, see Feature Descriptions.

Although raster layers do not have fields, ArcGIS Server creates fields and returns them in query results. If you are comfortable with web inspection tools, you can use this fact to find out the field names and use them in field tokens. To find out the field names, run your web inspection tool and perform an identify operation. The field names are displayed in the tool's console. For example, if a count field is returned, you can use a {count} field token in the feature description. You cannot use the Rich Text Editor to enter raster layer field tokens—you must manually enter them.

Disallow Identify Operations on a Raster Layer

To disallow identify operations on a raster layer:

  1. In Manager, edit the site that you want to configure, click Map in the side panel, and then click the Map Services tab.

  2. Click the drop-down menu icon beside the raster layer.

  3. Clear the Allow Identify Operations checkbox.

  4. Click Apply Changes.

You can also configure the Allow Identify Operations setting on the raster layer's Details tab.
