Adding Labels to Your Map
The goal of any map is to communicate information in the clearest possible fashion. Adding labels is one way to accomplish this task, but simply placing labels anywhere on a map doesn't necessarily help people understand the information presented. For example, it may not be obvious which feature a label belongs to, labels for different features may overlap, and, in some situations, labels for some features may even be omitted.
ArcMap provides multiple ways to control how and where labels display in relation to point, line, and polygon features. In this topic, you will learn advanced methods for modifying label properties and for creating and placing dynamic labels.
Dynamic Labels
• which features in the layer are labeled• the field, or fields, in the attribute
table that will be used for labeling• font settings such as size, color, and
style• placement of labels relative to the
features• the scale at which labels will be visible
are based on an attribute and display using ArcMap's default settings. If you want to change the appearance, placement, or visibility of the labels, you need to change the layer's label properties, which determine how the labels draw. Label properties you can set include:
Labeling a Feature
• Label features one at a time• Label features that don’t exist in
the database• Data view

Quality placement for Maplex for ArcGIS (you need Maplex Extension)
• Central location for labeling needs• Moved labeling-related dialogs to
toolbar• Label weight• Feature weight
Label Manager
• Central location for label classes• Easy access to common parameters
Positioning labels
• Points• Relative position to
feature• Preference priority
• Lines• Position relative to
line• Follow curve of line• Orient to page or line
• Polygons• Best position
Label Priority
ArcMap uses label priority ranking to determine the order in which labels will be placed on the map. Labels with a higher priority will generally be placed first. Labels with lower priority that conflict with higher priority labels may be placed at alternate positions or dropped from the map.
Label & Feature Weights
Setting label weights and feature weights establishes a ranking system for labels when there is a conflict with other labels or features on the map. The general rule with weights is that a feature cannot be overlapped by a label with an equal or lower weight.
Map Scale
Set a scale range for labels so that they don't display until the map scale reaches a larger scale.
1:100,000,000
1:20,000,000
Map Scale
Reference Scale
By default, as you zoom in and out on a map, the size of labels does not change. The point size is maintained as you zoom so that labels appear to be the same size relative to your screen. If you want the label text to scale with the map, you can set a reference scale.
Setting a reference scale fixes the size of the labels relative to the other features in the map at a specific scale. When you set a reference scale, the labels will remain at their current size in map units. After you set the reference scale, the text appears larger when you zoom in and smaller as you zoom out.
Set the Reference Scale
The reference scale is a property of the data frame, so labels for all layers are set to the same reference scale.
Label Classes
• Every layer starts with a single label class named "Default", which is symbolized with default symbology. New label classes can be added to the layer. You select the features that you want to group together in each label class by building a Structured Query Language (SQL) expression.
Label Classes - Creating
NOTE: If you convert layers with multiple label classes, each label class becomes an annotation class in the annotation feature class.
The Maplex Extension
Maplex for ArcGIS is an automated high-quality cartographic text placement and labeling extension for ArcGIS Desktop. Maplex for ArcGIS greatly reduces map production time and enhances cartographic quality.
Maplex for ArcGIS
• Better polygon placement styles• Straight• Boundary
• Improved user experience for stacking labels• Justification controlled by user
• New dialog to set up label abbreviations
• Reduce font size to place more labels
