Openstreetmap Background
Technological changes over the past 10 years, in combination with increased bandwidth and the ability to provide better tools for collaboration, have led to “crowdsourcing”4—a term developed from the concept of outsourcing in which business operations are transferred to remote, many times cheaper locations.5 Similarly, crowdsourcing is how large groups of users can perform functions that are either difficult to automate or expensive to implement.
