Engagement(Passive to Active)
•Participating: Becoming a member and agreeing to be tracked and sampled
•Collecting: Aiding one-off efforts, sharing personal perspectives, photos
•Mapping: Careful capture of details

Mapping Issues•Authority / Vetting / Quality assurance
• Good enough if I have it now (currency)
• Knowledge flows vs. authoritative silos (access)
• Quantity can trump quality (insight through analysis)
• Human fallibility (inconsistency)
•Obtaining adequate coverage• sensors to fill in the gaps
•Integration• multiple points of truth?
