Why Use Labels in Your GIS?

• Describe particular features
• Add general information to the map
• Add clarity
• Communicates you message to the viewer

4
Define and Contrast Labels, Annotation and
Graphics

• Labels
• A label is a piece of text in ArcMap that is
  automatically positioned and whose text string is
  based on feature attributes.
• They are generated dynamically and only labeling
  properties are stored.
• Labeling properties will be saved when you save
  your map document (.mxd) or layer file (.lyr).
• Labels offer the fastest and easiest way to add
  descriptive text to your map for individual
  features.
• Text size can be independent or tied to a
  reference scale.

5
Define and Contrast Labels, Annotation and
Graphics

• Annotation
• Each piece of annotation stores its own position,
  text string and display properties.
• The text or graphics can be individually
  selected, positioned and modified.
• Annotation may be manually entered or generated
  from labels.
• Text size is explicitly set based on a reference
  scale.
• Types of Annotation
• Geodatabase Annotation
• Stored in a geodatabase
• Map Document Annotation
• Stored in map documents

6
Define and Contrast Labels, Annotation and
Graphics

• Graphics
• Graphic text is stored on the map layout page.
• Cannot be organized into groups.
• Edited with the graphic tools on the Draw
  toolbar.
• Typically denoted as map layout features
• Map title
• Legend
• North Arrow
• Scale bar and text
• Text size is set relative to the map layout size.

7
Working with Labels

• Two ways to label features
• Label Toolbar
• gt View Menu gt Toolbars gt Labeling
• Label Tab
• Under Layer Properties

8
Working with Labels

• Label toolbar
• Label DropDown - Gives you access to Abbreviation
  Dictionary, Maplex tools and additional Options.
• Label Manager
• Label Priority Ranking
• Label Weight Ranking
• Lock Labels
• View Unplaced Labels

9
Label DropDown

• Abbreviation Dictionary contains acceptable
  abbreviations for labeling. Ex. street type
  abbreviations (St, Hwy, Dr, etc.)
• Maplex Labeling Engine
• Options
• Color of unplaced labels
• Rotation of labels
• Angle from vertical

10
Label Manager

• Label Manager has similar tools that are found in
  labeling.
• Simplifies Labeling tasks and label management
• Feature Classes
• Label Field
• Expressions
• Placement
• Scaling
• Styles

11
Label Manager

• Placement Properties
• Point
• Placement Around point, On point, Specify angle,
  Angle from field.
• Location Preferred Northeast corner
• Line
• Orientation Horizontal, Parallel, Curved, and
  Perpendicular
• Position Above, On the line, Below
• Polygon
• Placement Horizontal, Straight, Horizontal First
  then Straight

12
Label Manager

• Label Manager provides access to conflict
  detection and feature type specific placement.

13
Label Priority Ranking

• Label Priority Ranking ranks labels according to
  their placement. Labels at the top of the list
  have the highest priority and are most likely to
  be placed.

14
Label Weights

• Label Weight Ranking lets you set weights to
  labels in instances of conflicts (overlaps).
  Labels with a higher weight have higher priority.

15
Label Lock and Unplaced Labels

• Label Lock holds the positions of the labels in
  the current map extent. Label positions maintain
  as you pan or zoom in map extent. Labels outside
  of map extent do not draw until lock is turned
  off.
• View unplaced labels to see what needs to still
  be placed. Default color is red, can be changed
  in Label Options menu

16
Labeling All Features the Same

• Access the labels tab in the layer property
  dialog box.
• Things to consider
• Label all features the same way, or set each
  class differently
• What field is the label, Name, Object ID, etc.
• Text Symbol
• Placement Properties, Scale Range, Label Styles

17
Labeling FeaturesBased on Classes

• Label Classes
• When you have different symbol classes for a
  feature and you want to label those classes
  accordingly.

18
Label Symbology

• Labels can be created with backgrounds, leaders
  callouts, other symbols, shadows, and halos.
• Under Label tab in Layer Properties Symbol

19
Label Expressions

• Expressions can be used to format your labels.
• Limited to a single line of code
• Advanced option lets you enter a function
  containing a programming script that can span
  multiple lines.

20
Label Expressions

• Example expressions
• Single field Name
• Multiple fields FirstName LastName
• Stacked FirstName vbnewline LastName
• Formatted ltCLR Red 255gt ltFNT Size
  14gt Name lt/FNTgt lt/CLRgt
• Formatted text type FormatCurrency (Profit)

21
Label Expressions

• Mathematical equation Round (SHAPE.AREA)
  .00002295682) Acres
• Extract Attribute parts using Left Right, and Mid
  Functions
• Left(Name,1)
• Right(Name,1)
• Mid(Name,2,2)

22
Label Expressions

• Examples of Advanced VB Script
• Finding and replacing text
• Function FindLabel (STATE)
• Text Replace (STATE, Minnesota, MN)
• FindLabel text
• End Function
• A given criteria
• Function FindLabel(NAME, POPULATION)
• if (POPULATION gt 250000) then
• FindLabel NAME
• end if
• End Function

23
Working with Annotation

• Annotation Defined
• Another option in ArcGIS for storing text to
  place on your maps
• Stored in a annotation feature class
• Annotation features have a geographic location
  and attributes. Ability to change symbology
  including text, size, color, and other text
  symbol properties
• Two types of annotation Geodatabase and
  Map-Document

24
Geodatabase Annotation

• Two types of Geodatabase Annotation Standard and
  Feature-Linked
• Standard Annotation
• Not formally associated with a feature.
• Ex. Text on a map for a mountain range
• Feature linked annotation
• Annotation that is directly linked to features
  (point, line, or polygon feature class)
• Annotation is linked to its feature using a
  relationship class.
• Composite Relationship A link or association
  between objects where the lifetime of one object
  controls the lifetime of its relate objects.

25
Geodatabase Annotation

• Why use feature linked annotation?
• Additional functionality
• When a new feature is created, so is the
  annotation associated with it
• When a feature is moved the annotation associated
  with it moves as well
• Changing the attributes of a feature also changes
  the annotation associated with it
• Deleting a feature also deletes the annotation
  associated with it
• Must have ArcEditor or ArcInfo license to create
  and edit feature linked annotation. Read-only in
  ArcView

26
Geodatabase Annotation

• Creating Annotation from Labels
• Right click layer gt Convert labels to annotation
  gt dialogue box
• Store in Database or Map?
• All features, or selected features?
• Select Feature-Linked Annotation by checking box,
  leave unchecked for Standard Annotation
• Name annotation feature class
• Specify where it is to be stored
• Decide if unplaced labels become unplaced
  annotation
• Convert!

27
Geodatabase Annotation

• Creating Annotation from Scratch (Non-Feature
  Linked)
• ArcCatalog
• Create new feature dataset under database
• Create new feature class under dataset
• Define annotation classes
• Set reference scale
• Set defaults

28
Geodatabase Annotation

• Annotation Classes
• Contains properties that determine how a subset
  of annotation in the feature class displays
• Standard Annotation
• Default symbology
• Visible scale range
• Feature-Linked Annotation
• Standard Annotation properties
• How the annotation text strings will be defined
  based on attributes in the linked feature class
• Which features in the linked feature class will
  be annotated by the annotation class
• How to place new annotation

29
Geodatabase Annotation

• Reference Scale
• Must set reference scale for annotation
• Zooming in to larger scale, annotation will
  appear larger. Zooming out to smaller scale,
  annotation will appear smaller.
• Reference scale for annotation should match map
  reference scale.
• Ex. 50,000 Township, 9,000 Section, 4,000
  Detail
• Set your defaults to the annotation class you
  edit the most.

30
Geodatabase Annotation

• Editing Standard Annotation
• Edit Attributes
• Change type
• Change size
• Rotate
• Moving, Anchors/Handles
• Follow features
• Find Text
• Creating curved
• Converting to multiple parts
• Stacking
• Copy and Paste features

31
Geodatabase Annotation

• Editing Feature-Linked Annotation
• Similar to editing standard annotation.
• Editing the feature attribute of the parent
  feature will update the child annotation.
• Can over ride the default text by editing the
  attributes or text of the annotation, however
  this is rode by updating the parent feature.

32
Map-Document Annotation

• Map document annotation is stored inside the map
  document (.mxd).
• Useful if you have a relatively small amount of
  editable text.
• Text can only be used in a single map.
• Map document annotation is best organized using
  annotation groups.
• Create annotation groups in ArcMap by using the
  Draw toolbar.

33
Maplex Labeling

• What is Maplex?
• High quality cartographic labeling extension for
  ESRI ArcMap.
• User defined label placement and conflict
  resolution.
• Text placed quickly, without overlap and little
  manual adjustment needed.

34
Maplex Labeling

• Benefits to Maplex
• Flexible placement allowing more labels to fit in
  an area
• Label fitting strategies allowing for better
  placement of labels
• Ability to resolve conflicts of overlapped,
  unplaced, and poorly placed labels

35
Loading Maplex

• Maplex is loading like any other extension
• Tools Menu gt Extensions

36
Loading Maplex

• Once Maplex is loaded it is necessary to set it
  as the desired labeling engine.
