Module 8 - Database design and Final Project

Review this supplemental document on geodatabase design as well as looking back over your lecture notes and the PowerPoint from our geodatabase design discussion.

Begin to explore this Final Project for this class.

Topology in ArcGIS

LEARNING OBJECTIVES

1. Define topology
2. Describe map topology
3. Describe geodatabase topology
4. Describe coincidence
5. Explain how topology helps with analysis and data integrity
6. Define cluster tolerance
7. Define ranks in a topology
8. List several topology rules
9. Describe topology validation
10. List several types of topology errors
11. Discuss 2 ways topology errors may be fixed.

TERMS TO KNOW

• topology
• map topology
  
• geodatabase topology
• connectivity
• adjacency
• containment
• validation
• topology errors
• data integrity
• coincidence
• cluster tolerance
• ranks
  

CLASS DISCUSSION

In ArcGIS there are 2 types of topology.

• Map Topology: Available at the ArcView license. Used during an edit session to ensure coincident features maintain coincidence while editing.

• Geodatabase Topology: Available only with ArcEditor and ArcInfo licenses. Powerful rule based topology that help with data validation.

** See supplement resources below for more information on both these topics.
