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?
