Add the Identify Route Locations tool to ArcMap and find the measured value of a location along a route

ArcMap gives you the ability to point to a route in a map and find the route identifier along with the measure value at that location. In this example you will see how to use the Identify Route Locations tool to inspect the measure values on routes.
The Identify Route Locations tool does not appear on any toolbar by default. You will have to add it to one. To do so, click Tools and click Customize, click the Commands tab and click Linear Referencing in the Categories list. Drag and drop the Identify Route Locations tool to the toolbar of your choice. In this example it is added to the Tools toolbar.
In this example you see how to use a bookmark to zoom to an area containing some of the calibration points that were used to recalibrate one of the routes on this map. When you view this location, the calibration points appear with labels that represent the measure values for each point.
To see the measure value for a location, click the Identify Route Locations button. Move the mouse pointer over a route near one of the calibration points and click. In this example, route locations from both the routes and routes_new layers on this map are identified.
Because more than one feature is identified, a node for each feature appears in the left side of the Identify Route Location window. Click the route node for each to see the results for both of the route layers.
The numeric value listed for each of these nodes corresponds to the value stored in the Route Identifier field. Note that in this example the measure values for the two routes differ. The measure value for the routes_new layer corresponds closely to the measure value of the nearest calibration point. The measure value for the uncalibrated route will be slightly different.
If you right-click the route node for one of the layers you can see some context menu choices. You can flash the route or the route location, set a bookmark, draw a graphic marker for the route location, label the route location, or use the Identify tool to get more information about the route feature you clicked.
The right panel of the Identify Route Locations dialog box shows you the measured location on the route where you clicked, as well as the minimum and maximum measure values for this segment, how the measures are distributed on the route, the number of segments on the route, and whether or not the route contains unknown measure values.
