Multiple Approaches
Connecticut State Data Center & Map and Geographic Information Center - MAGIC

• Spreadsheets are great… but it’s difficult to understand with large datasets
• Examine Concepts from multiple perspective– Spatial– Temporal
• Integrate data from multiple sources• Ex. Fault lines, earthquakes, and population data
• Interac ve ≠ expensive or difficult
