Calling on Crowds
Matt Ball, Vector1 Media@spatialsustain
Crowdsourcing is the act of sharing a job or function that was once the domain of a specific agent with distributed masses through an open call.- Wikipedia
Definitions
Volunteered geographic information (VGI) is the harnessing of tools to create, assemble, and disseminate geographic data provided voluntarily by individuals.
- Michael GoodchildParticipatory sensing tasks everyday mobile devices to form interactive networks that enable public and professional users to gather, analyze and share local knowledge.

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?
