Working with Geodatabase Domains and Subtypes (for ArcGIS 10)

Description

A GIS is only as good as the data it stores. When data entry errors occur, the integrity of your database comes into question, and so does the reliability of any products derived from that data. When you store your data in a geodatabase, you can take advantage of components designed to make editing tasks faster and more accurate. In this course, you will learn how you can use domains and subtypes to maximize editing efficiency and minimize potential for error.

Who Should Attend

GIS specialists, data technicians, data managers, and others who need to manage and maintain GIS data stored in a geodatabase.

Learn How To

• Understand the difference between a domain and a subtype.
• Choose the appropriate domain type for the data being stored.
• Create two types of domains and apply them to fields in a geodatabase feature class.
• Enter and validate feature attribute edits using domains.
• Create subtypes to organize categories of features within a feature class.
• Assign a default subtype to reduce the time spent creating new features.
• Associate a subtype with domains to enforce valid attribute values for specific types of features.

To complete course exercises, you need the following software:

• ArcGIS 10.0 for Desktop (ArcView, ArcEditor, or ArcInfo)

Maintaining data integrity with domains

• Enforcing data integrity
• Anatomy of an attribute domain
• Types of attribute domains
• Editing with range domains
• Null and default values
• Create and use attribute domains to streamline editing
• Choose the appropriate domain type

Using domains and subtypes together

• Enforcing data integrity with subtypes
• Anatomy of a subtype
• Categorize your data with subtypes
• Using subtypes and domains together
• Use subtypes with domains
• Organize the geodatabase

Completion of Getting Started with the Geodatabase (for ArcGIS 10) or equivalent knowledge is required.
