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
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:
• 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
Labeling a Feature
• Label features one at a time
• Label features that don’t exist in
the database
• Data view

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
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 highquality 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
Stacking Text With Maplex
• Dynamic stacking
• Automatic stacking
• Space, hyphen, comma
• Automatic justification
• Left, right, center
• Controlled stacking
• User-defined characters
• Forced stacking
• Controlled justification
Stacking text without Maplex
• How do you stack text from two
fields in ArcGIS?
• [Field1] + [Field2]
• Use Visual Basic code in
expression.
• vbnewline (like using the Enter key)
• [Field1] & vbnewline & [Field2]
• Returns:
– Field1
– Field2
Stacking labels without Maplex for ArcGIS
• How do you stack text in one field?
• MyField = “Dr. Jekyll & Mr. Hyde”
• Visual Basic code in expression
TopHalf = Left (MyField, (InStr (1, MyField, “&”)))
BottomHalf = Right (MyField, ((Len (MyField)) – (InStr (1, MyField,
“&”)))
TopHalf + vbnewline + BottomHalf

Abbreviations without Maplex for ArcGIS
• How do you abbreviate text?
• PolyVinyl Chloride = PVC
• Ductile Iron = DI
• Use Visual Basic code in
expression
• Select Case statement
• Select Case [Material]
– Case “PolyVinyl Chloride”
» FindLabel = “PVC”
– Case “Ductile Iron”
» FindLabel = “DI”
• End Select

Converting Labels to Annotation
After investing time to create labels, why would
you want to move on to annotation? Unlike
dynamic labels, with annotation you can:
• create unique text symbology to identify a specific
feature
• position the annotation exactly where you want it
• place informational text, not associated with a
feature, on your map
• include graphics
• edit an individual piece of annotation text or its
symbology
• share annotation data without necessarily sharing
a map document
Converting Labels to Annotation
Feature-Linked Annotation
Annotation that is stored in the geodatabase
with links to features through a geodatabase
relationship class. Feature-linked annotation
reflects the current state of features in the
geodatabase: it is automatically updated

Map Document Annotation
•
Visibility of layers is controlled on a layer-by-layer basis
in the ArcMap Table of Contents. Visibility of map
document annotation is controlled by annotation
groups in the properties for the data frame.
Editing Annotation
You can modify annotation stored with the
map document right where you see it, without
starting an edit session. Any edits you make
to this type of annotation apply only to the
ArcMap document (.MXD) in which you made
the changes.
When you modify geodatabase annotation
attributes, you must make those changes in
an edit session. You edit a geodatabase
annotation feature class just as you edit the
feature class of a geometric feature.
Managing Annotation
• Expose annotation properties as
individual feature attributes
• Supports queries against text symbol
information
• Allows for bulk updates to symbol
properties
