Identify Module

The Identify Module implements identify operations. It provides a set of configurable tools, each of which runs an Identify command on a particular type of geometry. The tools return a collection of features that intersect the geometry that the user draws on the map. The feature set collection is then used by some other module, which renders the feature set collection in its view.

For example, the MapTips Module uses the Identify command to identify a feature located at a particular point. The MapTips view then renders the feature returned by the Identify command.

WMS layers that are not associated with a WFS only support point identify operations, whereas WMS layers associated with a WFS support all types of identify operations.

As of HTML5 Viewer 2.5, the user can choose which layers are affected by the Identify tools by clicking the Identifiable Layers button. Users can also enable buffering to identify nearby features.

The Identifiable Layers button is configured in context-sensitive toolbars within the TabbedToolbar and CompactToolbar modules. The easiest way to configure this feature is to edit your viewer in Geocortex Essentials Manager, and open the viewer's Toolbar page.

To enable this feature for the standalone Identify tool in the tabbed toolbar, ensure both Identify and IdentifyToolControlRegion are included in your configured toolbar.

To enable this feature for the Identify multitool in the tabbed toolbar, ensure both Find Data and FindDataControlRegion are included in your configured toolbar.

In the case of the compact toolbar, do not include the regions.

The Identify multitool also provides options to add to existing identify results or to subtract from existing identify results. (These options are not currently available for handheld devices.) To add to existing results, click Identify to open the menu, click Enable Add Results, then click another item on the map to add it to the results list. Similarly, to subtract from existing results, click Identify to open the menu, click Enable Subtract Results, then click an item previously identified to remove it from the results list.

By default, Identify is turned off after each use. To continue to add to or subtract from the identify results, click Identify and click or tap another location on the map. When the user closes the Results List or Table, the features that were listed are discarded.

Note that if Enable Add Results is active and the user clicks Enable Subtract Results, the add results option is disabled. Similarly, if Enable Subtract Results is active and the user clicks Enable Add Results, the subtract results option is disabled.
