Review Questions 1. Jenks method, one of the most commonly used standard classification methods, is based on natural groupings inherent in the data, setting boundaries where large gaps between values occur. True/false? 2. Dot density maps show the distribution pattern of the data. True/false?

Review Questions 3. A chart map is used to represent multiple attribute values for a single feature. True/false? 4. The classification method of Standard deviation works best for normally distributed (bell-shaped curve) data.

Lect 6 Labeling Features Using dynamic labels Setting rules for label placement Creating graphic labels using Text tool on the Draw toolbar Converting dynamic labels to annotation

Label Any text that names or describes a feature Represents values in a layer attribute table Stays close to a feature associated with

Three Types of Labels Dynamic labels: Added to all features in a single click; Behave as a group; No precise control of appearance and placement Interactive Labels: Add text by using Text tool on the Draw toolbar Annotation: Static text or graphics that you can individually select, modify Have significant control of appearance and placement

Ex 9a Dynamic Labels Use Properties/Labels Turn on/off, change symbol or attribute value as a group Label position changes depending on Placement of other features/labels Map scale

Ex 9b Label Placement Labels for points: eight positions Labels for lines: three positions Labels for polygons: close to the center of the polygon Setting label and feature weights to avoid labeling conflict Labeling Toolbar: Label Manager

Ex 9c Creating Graphic Labels (Dynamic Labels) Use the text tools on the Draw toolbar Use for only a few features, or base layers with no attributes

Ex 9d Converting to Annotation Select, move, and modify annotation piece by piece Typically do this when your map is nearly finished and want to make final adjustments Annotation can be saved in a map or a database ArcGIS Desktop Help- Contents- Desktop/Mapping/Adding text to map/Converting labels to annotation
