# Blue Locate Tool – Apply Feature Label Graphics

The two key components of labeling features for the Blue Locate tool are accurately placing and sizing the label graphics, and assigning useful names to the features.

#### Label placement and sizing

You perform Labeling with the Blue Locate tool by using your mouse and clicking on the features you want to identify, which places a feature label graphic as an overlay on the feature in the image. ViDi will perform the best when the center point of the feature label graphic is placed on an interesting feature where there is a lot of information on it. A good example is to place the feature label graphic on an intersection of some edges, rather than a random point on a single edge.

The label sizing is determined by the Feature Size parameter, and whether or not the Scaled parameter is enabled. See the Blue Locate Tool – Feature Size and Set a Feature Label Graphic to Scaled topics for more information.

#### Label naming

Once you have clicked on the feature, the feature label graphic will be displayed, and you will need to assign a name to the feature. The name can be up to 140 Unicode characters.

There are two ways to assign a name to a feature label graphic:

1. Click on the feature, and when the editing cursor appears, you can either type in the name, or paste in a name, up to 140 characters long.
2. In the Database Overview, select the text for the feature and press the pencil icon to either type or paste in the name.

After adding a name, press the Enter key.
