About PlaceBazaar

Placebazaar is a platform where contributors are paid to maintain and add data to a decentralized, worldwide map of roads, trails, cafés, public transport and much more.

PlaceBazaar connects parties in need of mapping data, with contributors of that data, on a marketplace. Built on top of the fantastic OpenStreetmap data, we ensure the data is uncensurable and allow contributors to get paid for their work.

How does it work?
