Geographic technologiesP iti i th E th’ f• Positioning on the Earth’s surface– GPS, RFID
• Acquisition systems• Acquisition systems– remote sensing– volunteered geographic informationg g p
• Data dissemination– geoportals– virtual globes
• Analysissearching for patterns and anomalies– searching for patterns and anomalies
– testing hypotheses, modeling change

Lessons learnedA th it ti i f ti• Authoritative information– sparse observer network– must be verified by officialsy– too slow for the Tea and Jesusita Fires
• Asserted informationd b t k– dense observer network
– carries risk of false positives• false rumor of a fire in Mission Canyon• some unnecessary evacuations
– people are willing to accept false positives– lack of authoritative information amounts to false negativesg– false negatives are far less acceptable than false positives
• there were some posted false negatives
